  • The objective of this study was to investigate the effects of administration methods for on Garcinia cambogia on blood Garcinia cambogia concentration and antioxidative levels. Rats were divided into three groups: G1 (normal group), G2 (one administration of Garcinia cambogia extract 2,800 mg/kg b.w.), G3 (three separate administrations every 6 h of Garcinia cambogia extract 750, 850, and 1,200 mg/kg b.w. for 18 h). Blood samples were collected every hour, and animals sacrificed 18 h after the oral administration of Garcinia cambogia extract. We examined changes in the serum concentration of Garcinia cambogia by HPLC analysis. Two hours following an oral administration of Garcinia cambogia extract (2,800 mg/kg b.w.), serum Garcinia cambogia levels reached their maximum, but gradually decreased until 10 hours when it was no longer detectable. In contrast, serum Garcinia cambogia levels under G3 administration were maintained above a certain level after 18 h. To determine whether this level of Garcinia cambogia could affect blood oxidative levels, we measured serum lipid peroxidation by TBARS levels. TBARS levels from G3 treatment were significantly lower than G1 and G2. To analyze other antioxidative activities, radical scavenging activities were measured by the DPPH and ABTS radical scavenging assays. There were no significant differences between the groups in DPPH radical scavenging activity. However, ABTS radical scavenging activity significantly increased with G3 treatment compared with G1 and G2. In conclusion, our data show that three times administration of Garcinia cambogia every 6 h may helpful for maintaining serum Garcinia cambogia levels and antioxidative effects.

  • To develop functional kimchi which had anti-obesity effect, garcinia cambogia extract containing $51.46\%$ hydroxy citric acid (HCA) was used as a sub-ingredient of American preferred kimchi (APK). The APK added to garcinia cambogia extracts of 0.5$\%,\;1.0\%,\;1.5\%\;and\;2.0\%$ were prepared, and fermentation characteristics and anti-obesity effect of those kimchi were investigated. The pH of APK added to garcinia cambogia extracts (APKH) was low as the amount of garcinia cambogia extract increased at initial stage of fermentation but the pH of those kimchi showed similar values after optimum ripened stage. The number of Lactobacillus sp. and Leuconostoc sp. were small as the amount of garcinia cambogia extract increased while the period was delayed that the number of Lactobacillus sp. and Leuconostoc sp. attained to maximum. In Hunter's color values of APKH, lightness and redness decreased as the amount of garcinia cambogia extracts increased while yellowness increased. Sensory scores in overall acceptance, taste and texture of APKH evaluated by Americans as sensory panels were similar until the addition amount of garcinia cambogia extract was $1.5\%$, therefore the garcinia cambogia extract of $1.5\%$ was determined as tile amount adding to APK. The secretions of glycerol and leptin as a key signalling factor for anti-obesity effect were examined in APK and APKH added to garcinia cambogia extract of $1.5\%$. There were no significant differences in the glycerol secretion when adipocytes were treated with APK and APKH extracts. However, leptin secretion in the adipocytes treated with APKH extract was significantly decreased compared to that of control (p<0.05).

  • In this study we examined effects of a new dietary supplement on the lipid level and body weight. The efficacy of this weight-reduction supplement, based on natural ingredients consisting of Phaseolus vulgaris, Garcinia cambogia, and microstalline cellulose, was investigated by randomized, placebo-controlled double-blind study. The 36 subjects were assigned evenly into weight-reduction supplemented (Active) and placebo groups (Placebo). The supplement could reduce the absorption of different types of sugar from the gastro-intestinal tract. A significant difference in weight reduction was shown in the active group (3.5 kg). Body composition measurements indicated that about 34% of fat loss in the active group could be achieved. These findings suggest that this dietary supplement could reduce body weight and fat gains, and its inhibitory effects might lead to obesity improvement.

  • This study aimed to examine the mechanisms underlying the effects of Garcinia cambogia extract on the adipogenic differentiation of 3T3-L1 cells and long-chain saturated fatty acid-induced lipotoxicity of HepG2 cells. 3T3-L1 preadipocytes, mouse embryonic fibroblast-adipose like cell line, were treated with MDI solution (0.5 mM IBMX, 1 ${\mu}M$ dexamethasone, 10 ${\mu}g/mL$ insulin) to generate a cellular model of adipocyte differentiation. Using this cellular model, the anti-obesity effect of Garcinia cambogia extract was evaluated. MDI-induced lipid accumulation and expression of adipogenesis-related genes were detected by Oil red O staining, Nile Red staining, and Western blot analysis. Effects Garcinia cambogia extract on palmitate-induced lipotoxicity was also analyzed by MTT assay, LDH release, and DAPI staining in HepG2 cells. Garcinia cambogia extract significantly suppressed the adipogenic differentiation of preadipocytes and intracellular lipid accumulation in the differentiating adipocytes. Garcinia cambogia extract also markedly inhibited the expression of peroxisome proliferator- activated receptor ${\gamma}2$ ($PPAR{\gamma}2$), CCAT/enhancer-binding protein ${\alpha}$ ($C/EBP{\alpha}$), and adipocyte protein aP2 (aP2). In addition, Garcinia cambogia extract significantly attenuated palmitate-induced lipotoxicity in HepG2 cells. Palmitateinduced cellular damage and reactive aldehydes were also significantly reduced in the presence of Garcinia cambogia extract. These findings suggest that the Garcinia cambogia extract inhibits the adipogenic differentiation of 3T3-L1 preadipocytes, probably by regulating the expression of multiple genes associated with adipogenesis such as $PPAR{\gamma}2$, $C/EBP{\alpha}$, aP2, and thereby modulating fatty acid-induced lipotoxicity to reduce cellular injury in hepatocytes.

  • Objectives: Obesity is becoming more popular disease worldwide. Because of the side effects of conventional obesity treatment modality, herbal medicine treatment is becoming more preferred. Gambihwan which including Ephedra sinica Staph is widely used in traditional Korean Medicine practice for obesity treatment. Garcinia cambogia is a kind of health functional food that has body fat reducing effect. Nowadays, ephedra and Garcinia cambogia are often used simultaneously in clinical practice of Korean Medicine. However, the effectiveness and safety of combination therapy in obesity treatment is not well established. Methods: We conducted retrospective observational study to explore effectiveness and safety of combination therapy. We evaluated effect of combined treatment of Gambihwan and Garcinia cambogia on body weight, body mass index, body fat mass, and waist hip ratio reduction. We also assessed safety via liver function test and adverse event. Results: Finally, 23 patients were included. In paired t-test, body weight significantly decreased from 64.50±14.50 kg to 62.94±13.85 kg (P<0.001) and body mass index were also significantly decreased from 24.43±3.79 kg/㎡ to 23.83±3.59 kg/㎡ (P<0.001). Body fat mass was also reduced. Aspartate transaminase and alanine aminotransferase were not significantly increased. There were no drug-induced liver injury and no severe adverse event. Conclusions: In our retrospective review, we found combination therapy of Gambihwan and Garcinia cambogia reduce body weight, body mass index and body fat mass. There were no severe adverse event and drug induced liver injury which indicated safety of combination therapy in obesity treatment.

  • This study was designed to evaluate the effects of high-carbohydrate (HC) or high-fat (HF) diet with hydroxycitric acid (HCA)-containing Garcinia cambogia in rats. Seventy male Sprague-Dawley rats were randomly divided into 7 groups and raised with experimental diets containing different HCA levels (0, 1.6, and 3.2%) and calorie sources (carbohydrate, fat) for 8 weeks. Energy intake was significantly reduced in rats fed a HC diet with HCA compared to the HC diet without HCA. Body weight gain was significantly reduced in HCA groups. In the diet groups, plasma total lipid and triglyceride (TG) levels of the HCA groups were significantly lower than those of the group without HCA. There were no significant differences in energy intake and plasma lipid profile in HF groups. These results suggest that HC diet with HCA was more effective in the reduction of energy intake, body weight gain, and plasma lipid contents than those of HF diet with HCA.

  • This study was performed to investigate effects of the experimental mixture containing soybean peptides, L-carnitine and Garcinia Cambogia extract on body weight and lipid metabolism in rats. Male Sprague-Dawley rats (n=40) of eight weeks old were raised for four weeks with high fat diet (40% fat as calorie) to induce obesity. After induction of obesity, rats were feed control (C) diet, containing either 0.16% (+1D), 1.6% (+10D), 8% (+50D) of experimental mixture for eight weeks. Plasma aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activity and total protein and albumin concentration were not different among groups. The Body weight gain was significantly lower in experimental mixture diet group compared to control group. Weights of perirenal fat pad and epididymal fat pad in the +50D group were significantly lower than those in the +1D and +10D groups. Plasma total lipid and liver total cholesterol levels in the experimental groups were significantly lower than those in the control group. Fecal total lipid and total cholesterol excretions were highest in +50D group. These results suggest that the experimental mixture containing peptides, L-carnitine and Garsinia Canbogia extract is effective for reducing the body weight and adipose tissue weight which may be due to the modulation of lipid metabolism and the increased fecal excretion of lipid.

  • This study was undertaken to examine effects of dietary intake of garcinia cambogia extract, soy peptide and L-carnitine mixture on body weight gain and obesity-related bio-markers in rats fed high-fat diet for 9 weeks with or without regular treadmill exercise. Forty 5-week-old male Sprague-Dawley rats were randomly divided into four groups; sedentary control group (SC), exercised control group (EC), sedentary formula-fed group (SF), and exercised formula-fed group (EF). The SC and EC rats were fed high-fat control diet (fat comprises$40\%$ of total caloris), and SF and EF rats were fed high-fat formula (composed of garcinia cambogia, soy peptide and L-carnitine) supplemented diet. Statistical analyses by two-way ANOVA indicated that the regular treadmill exercise significantly lowered cumulative body weight gain, total visceral fat mass, and epididymal, perirenal and retroperitoneal fat pad weights, and serum concentrations of total cholesterol and LDL + VLDL cholesterol, insulin, c-peptide and leptin. Feeding the formula also resulted in significant reductions in cumulative body weight gain and visceral fat pad weights, along with other related parameters including serum total and LDL + VLDL cholesterol levels, and hepatic enzyme activities involved in fatty acid synthesis. Statistical analyses by one-way ANOVA revealed that the formula consumption significantly improved body weight gain ($18\%$ reduction), total visceral fat weight ($20\%$ reductions), and serum total ($43\%$ reduction) and LDL + VLDL cholesterol ($54\%$ reduction) levels, as well as serum levels of insulin ($49\%$ reduction), and c-peptide ($41\%$ reduction) in sedentary rats, but failed to exhibit significant reductions in these indices in animals under treadmill exercise program. Taken together, these results suggest that the treadmill exercise per n exhibited significant improvements in body fat reduction and other related bio-markers, and so the formula consumption did not achieve a further significant reductions in these bio-markers in exercised rats. Nevertheless, animals fed the formula with regular exercise showed the most efficient weight reduction compared to other groups either fed formula without exercise or received regular exercise without dietary supplementation.

  • Background: There is abundance of studies on the decrease in body fat through limited calorie intake or exercise; however, studies focusing simultaneously on functional foods and exercise are rare. This study was aimed to identify the effects of combination of a functional beverage and exercise on body composition and biochemical metabolic profiles. Method: Eighty-one healthy volunteers (69 females aged 19 to 50 years and 12 males aged 19 to 55 years), who maintained their body weight stable with 23 or higher in BMI (kg/$m^2$) and 25% or higher body fat for the last three months, were recruited in the study through written advertisement. All the subjects gave their informed consent, and the study was conducted in accordance with the Declaration of Helsinki. The study design was a randomized double-blind placebo-controlled parallel group design. All participants were given 12-week programed-exercise, which was performed 3 times a week. One bottle (100 ml) of test (Garcinia cambogia 300 mg, L-carnitine 20 mg, Soy peptide 1,000 mg) or placebo solution was given daily 30 min before each session of programed-exercise. BMI (body mass index), %fat, local fat amount (visceral and mid-thigh), waist circumference, skin fold thickness and some biochemical metabolic parameters like glucose, insulin and free fatty acids, etc in the blood were measured and compared before and after 12-week intervention within groups as well as between groups according to the protocol Results: Twenty six volunteers were dropped out and fifty five volunteers completed the study. At the end of 4, 8, and 12 weeks, approximately 1.98%, 3.00% and 3.50% losses of initial body weight were observed, respectively, in the test group (P<0.01), and 0.29, % ,0.74%, 1.60%, respectively, in the placebo group (P>0.05). BMI changed by 2.40%, 3.41% and 4.46%, respectively, in the test group, and 0.38%, 0.95% and 1.75%, respectively, in the placebo group, at each period of time. The reductions of body weight and BMI were significantly higher in the test group than in the placebo group at each period of time (P<0.05). Conclusions: It is thought that the combination of functional beverage, which contains mostly garcinia cambogia, L-carnitine, and soy peptide, and exercise have synergy effects on reducing body fat.
