  • This study was conducted to ascertain the antioxidant properties of Hamcho (Salicornia herbacea L.) and as well as manufacture pettitoes using Hamcho as a natural antioxidant material for diverse applications. The DPPH radical scavenging activities of 25, 50, 100 mg/mL in methanol extracts from Salicornia herbacea L. increased significantly (p<0.05) to 12.8%, 21.6% and 39.1%, respectively. The total phenolic content was $38.58{\pm}4.25{\mu}M$ as tannic acid equivalent for 100 mg/mL of methanol extracts from Hamcho. FRAP value was $448.58{\pm}14.01{\mu}M$ as ascorbic acid equivalent in reducing power. To apply Hamcho to food as a natural antioxidant, pettitoes were prepared with added Hamcho. To manufacture pettitoes added with Hamcho, general quality characteristics of pettitoes added with 0%, 2%, 4% and 6% based on 100 g of pettitoes were determined. In conclusion, mineral components increased according to the added amount of Salicornia herbacea L. Crude protein showed the highest value with 2% added Hamcho. Overall, the addition of Hamcho led to hardening of the meat texture. As a result of measuring color in terms of brightness, redness, and yellowness with chromaticity, the L value (brightness) increased with added amount of Hamcho. There was no significant difference in redness or yellowness. As a result of the sensory evaluation of pettitoes according to addition of Hamcho, the group with 4% added Hamcho showed enhanced overall preference with improved flavor, taste and textural properties.

  • Hamcho (Salicornia herbacea) extracts were evaluated for total polyphenol content, antioxidant and pro-oxidant activities. The total polyphenol content was 1.81 g and 0.72 g per 100 g of dried sample in water and ethanol extracts respectively. Both water and ethanol extracts of Hamcho significantly exhibited antioxidant activity. The scavenging activity of hydroxyl radical was 13.8~26.2% and 14.2~16.0% in water and ethanol extracts respectively. The inhibitory effect of conjugated diene formation was 24.6~39.1% and 28.4~39.6% in water and ethanol extracts respectively. However, pro-oxidative effect was also observed in the Hamcho extracts. The Hamcho water extract showed the pro-oxidant effect by enhancing the formation of hydroxyl radical and conjugated diene. The ethanol extract of Hamcho induced conjugated diene formation at 0.5 mg/mL but not at 1 mg/mL. The hydroxyl radical formation was not induced by the Hamcho ethanol extract. Taken together, these results show that Hamcho extracts can act as pro-oxidants by generating hydroxyl radical or conjugated diene in addition to their antioxidant properties. Therefore, this study suggests that the physiological properties of Hamcho and its use as food materials should be considered with caution because antioxidant dietary plants such as Hamcho possess possible adverse effects induced by pro-oxidant activity.

  • The antioxidant activities of water ($H_2O$) and ethanol (EtOH) extracts from hamcho (Salicornia herbacea L.) juice and cake prepared by enzymatic treatments were evaluated by in vitro assays against DPPH, superoxide, and hydroxyl radicals. Among the $H_2O$ and EtOH extracts from five different carbohydrases treated, the EtOH extract from viscozyme-treated hamcho cake had higher yield and phenolic content, and exhibited the strongest radical scavenging activity against DPPH ($IC_{50}=186.91\;{\mu}g/mL$), superoxide ($IC_{50}=87.54\;{\mu}g/mL$), and hydroxyl radicals ($IC_{50}=367.07\;{\mu}g/mL$). Antioxidant assay-guided fractionation and purification of the EtOH extract led to isolation and identification of five phenolic compounds, procatechuic, ferulic and caffeic acids, quercetin, and isorhamnetin. Most of these phenolic compounds exhibited considerable DPPH, superoxide, and hydroxyl radical scavenging activities, and in particular, caffeic and ferulic acids had stronger superoxide and hydroxyl radical scavenging activities than the well-known antioxidant radical scavenger, (+)-catechin (p<0.05). Quercetin and isorhamnetin were the primary compounds responsible for the strong antioxidant activity in the EtOH extract of the viscozyme-treated hamcho cake. Meanwhile, these five phenolic compounds were detected in the EtOH extract of the viscozyme-treated hamcho cake at the following levels (dry base of hamcho); procatechuic acid (1.54 mg%), caffeic acid (6.87 mg%), ferulic acid (8.45 mg%), quercetin (12.63 mg%), and isorhamnetin (6.65 mg%). However, three of these phenolic compounds (procatechuic, caffeic acid, and ferulic acids) were detectable in the $H_2O$ extract of viscozyme-treated hamcho juice. These results suggest that the EtOH extract of viscozyme-treated hamcho cake may be a potential source of natural antioxidants.

  • Purpose: The objective of this study was to examine whether Hamcho freeze-dried powder and Hamcho freeze-dried nano powder have an anti-obese effect on high fat diet-induced obese rats. Methods: Sprague Dawley rats were divided into 6 different groups, each of which was bred for 8 weeks with a different experimental diet: normal diet group (NC), high fat diet group (HFC), high fat diet + 2% Salicornia herbacea L. freeze-dried powder group (2% HS), high fat diet + 5% Salicornia herbacea L. freeze-dried powder group (5%HS), high fat diet + 1% Salicornia herbacea L. freeze-dried nano powder group (1% HSN), high fat diet + 2% Salicornia herbacea L. freeze-dried nano powder group (2% HSN). Results: The 5% HS group showed a weight loss effect in body weight, liver and adipose tissue by reducing the amount of dietary intake and food efficiency ratio. In addition, the 5% HS group showed a significant reduction of serum leptin concentration, while having a beneficial effect on the improvement of lipid metabolism such as increase the serum concentration of adiponectin. However, Hamcho freeze-dried nano powder did not show a weight loss effect. Conclusion: Overall data indicated that Hamcho seemed to have anti-obesity effects. In particular, consumption of 5% Hamcho freeze-dried powder might have beneficial effects on body weight, serum adiponectin level, and lipid profiles since it led to reduced body weight and growth of adipose tissues by suppressing dietary intakes. However conduct of further research studies is needed for analysis of active components and biochemical action mechanism of Hamcho.

  • Hamcho(Salicorinia herbacea, glasswort), a halophyte, is an annual succulent shrub that grows on coastal wetlands and has been regarded as a functional food for good health. Natural dried red and green Hamcho were extracted with 25% ethanol and water at 70$^{\circ}C$. The antioxidant activities of these four extracts were examined by six different assays, including the measurement of total phenolics, radical scavenging effects on 1,1-diphenyl-2-picrylhydrazyl(DPPH), nitric oxide(NO) and nitrite(NO$_2$) scavenging effects, reducing power, and the inhibitory effect on tyrosinase activity. The total phenolic contents of the four extracts were high at 237 ${\sim}$ 255 mg of gallic acid equivalents per 1 g of dried sample tested. The green Hamcho extracts contained more phenolic compounds than the red Hamcho extracts. When they were compared to tocopherols, the antioxidant activities of the green and red Hamcho powders were significantly higher at the same concentration levels(5 mg and 3 mg, respectively) in a POV test. The inhibition effects of the four extracts at a level of 75 ${\mu}l$ were higher than 98% in the POV test. The red Hamcho 25% ethanol extract showed a high significant effect on DPPH radical scavenging(SC$_{50}$, 90.1 ${\mu}l$). The green Hamcho 25% ethanol extract, however, showed a high significant effect on NO radical scavenging(SC$_{50}$, 6.1 ${\mu}l$). The NO$_2$ radical scavenging effect was assayed at pH 1.2, 4.2 and 6.0, and all the Hamcho extracts scavenged the NO$_2$ radical much more effectively at pH 1.2. The NO$_2$ scavenging effect of the red Hamcho 25% ethanol extract(64%) was as high as that of 5 mM vitamin C at pH 1.2(p<0.05). In the reducing power test, the red Hamcho 25% ethanol extract revealed the highest ferric ion reducing activity among the Hamcho extracts, and its activity was as high as that of 0.33 mg/ml of vitamin C. The four Hamcho extracts showed high tyrosinase inhibition effects of more than 80%, and their activities were higher than 50${\mu}$g of kojic acid. The green and red Hamcho 25% ethanol extracts totally inhibited tyrosinase activity(100%). Therefore, the results suggest that red Hamcho extracts may serve as useful natural antioxidants along with green Hamcho extracts.

  • This study evaluated the quality characteristics of mungbean starch gel prepared with different amounts of Salicornia herbacea L. powder. In order to determine the optimal addition level of Salicornia herbacea L. powder, samples of mungbean starch with 0, 2, 4, 6 and 8% of Salicornia herbacea L. powder substitute were prepared, after which physicochemical, textural and sensory quality characteristics were measured. Upon increasing Salicornia herbacea L. powder levels in the formulation, moisture contents of samples decreased, except the 6% addition sample, and salinity levels increased. Total phenolic contents and DPPH radical scavenging activities also increased significantly upon addtion of Salicornia herbacea L. powder. According to the texture analysis, hardness and gumminess decreased with increasing amounts of added Salicornia herbacea L. powder. From the sensory tests, 4% Salicornia herbacea L. powder sample received the highest overall acceptability score with proper levels of flavor, saltiness and texture. As a result, to increase usage of Salicornia herbacea L., the optimal formulation consisted of 4% Salicornia herbacea L. powder substitute for mungbean starch.

  • The chemical compositions of amino acids, minerals, betaine, and polyphenolic compounds from Salicornia herbacea (Hamcho) according to harvest periods were analyzed. Changes of chemical characteristics in water and ethanol extracts from Hamcho were evaluated for titratable acidity, pH, soluble solid, and Hunter's color values. The antioxidative activity of water extract from Hamcho was also determined by DPPH $({\alpha},{\alpha}'-diphenyl-{\beta}-picrylhydrazyl)$ scavenging radical activity. Total polyphenolic compounds of Hamcho were shown the highest in August harvested by 201.6 ppm. The betaine of Hamcho water-extract was identified by high performance liquid chromatography (HPLC), which content was 0.248%, 0.269% and 0.204% in June, August, and October, respectively. Major compositional amino acids (mg%) were glutamic acid (582: 519: 664), proline (552: 471: 322), phenylalanine (480: 431: 424), aspartic acid (322: 297: 330), and arginine (282: 321: 483) in June, August, and October, respectively, and major free amino acids (mg%) were proline (9.7: 3.4), asparagine (6.7: 1.4), hydroxyproline (6.4: 2.8), valine (3.9: 2.5), arginine (1.7: 3.0) in June and August, respectively. Mineral contents (mg%) were Na (5,695: 7,536: 5,529), K (1,640: 963: 931), Mg (359: 428: 348), Ca (221: 234: 251), and P (207: 189: 259) in June, August, and October, respectively. Especially, K was high in June, Na and Mg were high in August, and Ca and P were high in October, respectively. DPPH scavenging radical activity was shown in the following order; 0.05% butylated hydroxytoluene (BHT)> August> June> October harvested Hamcho. The chemical components of polyphenolic compounds, betaine, amino acids and minerals were changed by harvest periods according to the growing season, and the highest concentrations of polyphenolic compounds and betaine of Hamcho were shown in August harvested.

  • This study was conducted to investigate the effects of water extract from enzymic-treated Salicornia herbacea (Hamcho) on lipid metabolism in rats fed high cholesterol diet. Experimental rats were divided into six groups which were composed of normal diet group, normal and $2\%$ Hamcho extract diet group, high cholesterol diet group, high cholesterol and $1\%,\;2\%\;and\;4\%$ Hamcho extracts diet groups. Body weight gain and food efficiency ratio (FER) of the high cholesterol diet group were significantly increased compared to the normal diet group, while those of the high cholesterol and Hamcho extracts diet groups were decreased compared to the high cholesterol diet group. Food intake was not significantly different among all experimental groups, The serum TG content of the high cholesterol diet group was significantly increased compared to the normal diet group, but that of the high cholesterol and extracts diet group was significantly decreased in dose-dependent concentration. The liver TG, total lipid and total cholesterol contents of the high cholesterol diet group were significantly increased compared to the normal diet group, while those of the high cholesterol and $2\%\;or\;4\%$ Hamcho extracts diet groups were significantly decreased compared to the high cholesterol diet group. The serum total cholesterol and LDL-cholesterol contents, and AI of the high cholesterol diet group were significantly increased compared to the normal diet group, while those of the high cholesterol and Hamcho extracts diet groups were decreased, and especially the high cholesterol and $4\%$ Hamcho extract diet group was significantly decreased compared to the high cholesterol diet group. Serum HDL-cholesterol contents of the high cholesterol diet group were significantly increased compared to the normal diet group. These results suggest that supplementation of water extract from enzymic-treated Salicornia herbacea may have a pronounced impact on lipid metabolism of serum and liver in the rats fed high cholesterol diet.

  • The purpose of the present study was to investigate the effect of enzymatic hydrolysate (extract) of Salicomia herbacea L. (Korean name: Hamcho) on antioxidative defense system in rats fed high cholesterol diet. Rats were divided into six experimental groups which are composed of normal diet group, normal diet group supplemented with 2% Hamcho extract, high cholesterol diet group, high cholesterol diet groups supplemented with 1%, 2% and 4% Hamcho extracts. The activity of serum glutamate oxaloacetae transaminase in rats was not different among all experimental groups, while the activity of glutamate pyruvate transaminase in groups supplemented with Hamcho extract was significantly lower than that of high cholesterol control group. Supplementation of Hamcho extract (SHE) to the high cholesterol fed rats resulted in increased activities of hepatic superoxide dismutase and glutathione peioxidase. However, there was no significant difference in the activity of hepatic catalase among all experimental groups. SHE also resulted in decreased levels of hepatic thiobarbituric acid reactive substances and mitochondrial carbonyl values. Those effects were higher to some extent in 2% and 4% Hamcho extract groups than those of high cholesterol control group. These results suggest that enzymatic hydrolysate of Hamcho may reduce oxidative damage by activation of antioxidative defense system in rats fed high cholesterol diets.

  • This study was designed to investigate the effects of enzymatic hydrolysates (EH) from Hamcho (Salicornia herbacea L.) on blood glucose and serum lipid status in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into normal and 5 diabetic groups. The diabetic groups were fed enzymatic hydrolysate-free control (DM) diets or diets supplemented with 0.02% (DM-2), 0.04% (DM-4), 0.08% (DM-8), and 0.16% (DM-16) of enzymatic hydrolysate for 4 weeks. Body weight gains were lower in five diabetic groups than that of the normal group. Blood glucose was decreased in EH-supplemented groups as compared to the normal group, and especially the lowest blood glucose levels were found in DM-4 and DM-8 groups. Activities of three disaccharidase in the middle part of the intestine, such as maltase, sucrase and lactase, in EH-supplemented groups were significantly lower than those of DM group. There was no significant differences in the activities of glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT) among all experimental groups. Serum triglyceride in DM group was significantly increased as compared to the normal group, but those of EH-supplemented groups were decreased to the normal level. Total cholesterol level in DM group was higher than EH-supplemented groups and normal group, but that of DM-16 group was significantly decreased to the normal level. HDL cholesterol level in DM group was significantly decreased compared to the normal group, but that of EH-supplemented groups was increased to the normal level. These results suggest that enzymatic hydrolysate from Hamcho has hypoglycemic and hypolipidemic effects on STZ-induced diabetic rats and may be useful as a dietary supplement for the treatment of diabetes.
