  • Objectives : The objective of this study is to study the effects of hot aqueous extract and ethanol extract from $Lonicera$ $japonica$ $Flos$ on nitric oxide(NO) and prostaglandin $E_2(PGE_2)$ production in macrophage. Methods : $Lonicera$ $japonica$ $Flos$ was extracted in two ways. One was extracted with distilled water(2L) for 4 h and the other one was extracted with 70% ethanol (2L) for 4h. The RAW 264.7 macrophage was subclutured. In order to evaluate cytotoxicity, MTT assay was performed. The concentrations of NO were measured by Griess assay. The concentrations of $PGE_2$ were measured by enzyme immunoassay. Results : 25, $125{\mu}g/m{\ell}$ hot aqueous extract from $Lonicera$ $japonica$ $Flos$ inhibited NO production in LPS-stimulated RAW 264.7 macrophages significantly. 25, 125, $625{\mu}g/m{\ell}$ ethanol extract from $Lonicera$ $japonica$ $Flos$ inhibited NO production in LPS-stimulated RAW 264.7 macrophages significantly. 150, $200{\mu}g/m{\ell}$ hot aqueous extract and ethanol extract from $Lonicera$ $japonica$ $Flos$ inhibited $PGE_2$production in LPS-stimulated RAW 264.7 macrophages significantly. Conclusions : This study suggests that hot aqueous extract and ethanol extract from $Lonicera$ $japonica$ $Flos$ suppress NO and $PGE_2$ production. So hot aqueous extract and ethanol extract from $Lonicera$ $japonica$ $Flos$ may have an anti-inflammation effect.

  • Background: A red seaweed, Callophyllis japonica has been traditionally eaten in the oriental area. In a recent study, it has been demonstrated that the ethanol extract of C. japonica have antioxidant activity. However, there are few studies about the effects of C. japonica on the function of immune cells. We investigated the immunomodulatory effects of C. japonica on the function of dendritic cells, the potent antigen-presenting cells. Methods: Bone marrow-derived dendritic cells (DCs) were used and the viability was measured by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay and trypan blue exclusion test. Cytokine and nitric oxide (NO) levels were determined by using ELISA and Griess reagent, respectively. The expression levels of DC surface markers were measured by flow cytometric analysis. Results: C. japonica ethanol extract did not significantly affect the DCs viability and the IL-12 production from DCs, irrespective of the presence of lipopolysaccharide (LPS). In addition, it did not significantly change the expression of DC surface markers. However, C. japonica ethanol extract significantly inhibited the LPS-induced NO production and also increased the proliferation of allogeneic lymphocytes activated by DCs. Conclusion: Our data suggests that C. japonica ethanol extract enhances the proliferation of allogeneic lymphocytes activated by DCs which is associated with inhibition of NO production from DCs induced by LPS.

  • The purpose of this study was to examine improvements in dye uptake, expression of various colors, and color fastness when washed or exposed to light. We examined these improvements by doing the combination dyeing of Juniperus chinensis heartwood and Alnus japonica heartwood extracts. In this study, two combination dyeing methods were used. One-bath dyeing involves combining Juniperus chinensis heartwood extract and Alnus japonica heartwood extract. Two-bath dyeing involves dyeing by sequence, which means that we dyed the Juniperus chinensis heartwood extract first and then dyed Alnus japonica heartwood extract sequentially (or in the opposite order). In terms of improving dye uptake, two-bath dyeing was more effective than one-bath dyeing. For cotton, dyeing Juniperus chinensis heartwood extract first and then dyeing Alnus japonica heartwood extract sequentially showed higher dye uptake in the two-bath method, while for silk, there wasn't much difference in the dyeing order. Through combination dyeing, red-violet color from Juniperus chinensis heartwood and brown color from Alnus japonica heartwood made various Y, YR, R series of color as a result. Moreover, combination dyeing improved fabric's fastness when washed or exposed to light. In the case of cotton, fabric dyed using two-bath dyeing, with Juniperus chinensis heartwood extract being the first dye, showed improvement in fastness to washing and light. And in the case of silk, fastness to washing and light improved regardless of dyeing order in two-bath dyeing.

  • Change in Quality properties of the Kochujang Prepared with the powder of Paecilomyces japonica and extract of p. japonica by different solvents were investigated during 90 days of fermentation at 20$^{\circ}C$. The moisture content was not significantly different, pH of Kochuiang made with p. japonica was lower than control group and decreased continuously according to the fermentation time. Amino nitrogen continuously increased till 60 days and decreased slightly on 90 days. Amino nitrogen of Kochujang made with P. japonica was higher than control group and was highest on 30 days and 60 days by 179.2mg% and 282.2mg% respectively. Value of L, a, b in Color decreased with proportion to fermentation period and L, a, b value of Kochujang made with P. japonica was lower and in particular that of Kochujang made with P. japonica powder was lowest. from the result of sensory evaluation test, the color of control group was similar to“clear red”but that of Kochojang made with powder of P. japonica was close to“dark reddish brown”and that of Kochujang made with extract of P. japonica was darker than that of control group and the preference of dark color was low. Texture was“glossy and smooth”in all and preference was high. In salty taste, the Kochujang by P. japonica addition was stronger and Kochujang made with extract was stronger than that made with powder. In hot taste, the Kochujang made with P. japonica was weaker than control group and the Kochujang made with P. japonica was scored higher in flavor than control group and Kochujang made with powder of P. japonica was the highest in score. In overall preference, the Kochujang made with P. japonica was better than control group like the result of flavor but expecially Kochujang made with water extract of P. japonica among the extract was best one unlike the result of flavor.

  • E. japonica is a well-known medicinal plant in Japan. The leaves of E. japonica were reported to have a hypoglycemic action. However, seeds of E. japonica are discarded and not used. To elucidate for anti-diabetic effects of E. japonica, Type 2 diabetic mice were allocated to control group, E. japonica leaf, and seed extract group. Animals were fed a 2018S Teklad global 18% protein rodent diet. Animals were received daily oral injections of E. japonica leaf or seed extract at a dose of 200 mg/kg body weight for 6 weeks. Body weight, food intake and water intake, and total adipose tissue weight of animals were significantly reduced by feeding of E. japonica leaf extract. All E. japonica extract groups significantly decreased fasting blood glucose, glycosylated hemoglobin levels, size of adipocytes and serum adiponectins. However, they did not have a beneficial effect on the serum triglyceride and cholesterol in the diabetic animals. These results suggest that E. japonica seed and leaf extracts have a antidiabetic effect by controlling of blood glucose and decrease of size of adipocytes in db/db mice and seed extract is more effective in hypoglycemic action than leaf extract.

  • Water extracts, ethanol extracts, and juice of Cusuta japonica, C, australis, and C. chinensis were prepared, and their cytotoxicity, antioxidant activity and inhibitory effects on tyrosinase activitiy and melanin biosynthesis were estimated by using melanoma Clone M-3. From this study; the following conclusions were attained. Extracts of Cuscuta japonica, C. australis, and C. chinensis showed noticeable cytotoxicity except ethanol extracts from the stem of C. australis. A maximual cytotoxicity was observed with tile ethanol extract from the seed of C, australis (87.39%). While the ethanol extract from the seed of C. japonica (91.88%) showed the most pronounced inhibitory effect on melanin biosynthesis, the water extract from the stem of C. japonica (1.05%) possessed very little inhibitory effect. The most inhibitory effect on tyrosinase activity was observed with the water extract from the stem of C. australis (76.67%). Howeverr the water extract from the stem of C. japonica showed a very poor effect on the inhibition of tyrosinase activity All the preparations, except extracts from the seed of C. australis were able to remove reactive oxygen species (ROS) in a dose-dependent manner. The juice of C. japonica demonstrated the strongest activity (59.02%).

  • In this study, we investigated the applicability of functional materials by examining a variety of physiological activities with the extract of Cleyera japonica leaf. Cleyera japonica extract showed a low cytotoxicity against murine melanoma B16F10 cells. In little or no cytotoxicity at concentrations, we showed that the treatment with Cleyera japonica extract resulted in a significant increase in the DPPH radical scavenging activity (IC50, 22.90 ㎎/L), similar to ascorbic acid (IC50, 18.65 ㎎/L) and anti-microbial activities against Bacillus subtilis, Escherichia coli, and Candida albicans. In particular, anti-microbial activities against Gram-positive bacteria was high. These results suggest that Cleyera japonica extract could be used as a natural preservative. Additionally, Cleyera japonica extract showed the inhibition of tyrosinase activity (IC50, 178.90 ㎎/L), similar to kojic acid (IC50, 89.13 ㎎/L) and decreased melanin content (IC50, 101.90 ㎎/L) higher than the control arbutin level (IC50, 100.65 ㎎/L), especially. Therefore, these results indicate that Cleyera japonica extract may be an effective material for functional cosmetics such as skin whitening materials.

  • This study was aimed at investigating hepatic toxicity and immunomodulating effects of defatted methanol extracts of two kinds of medicinal plants, Rubus coreanus Miq. and Atractylodes japonica Koidz. in mice. Defatted methanol extracts of fruits of Rubus coreanus Miq. and rhizome of Atractylodes japonica Koidz. were added at the level of 0.5% or 5%(w/w) to cholesterol-supplemented AIN-76 diet. Each diet was fed to 8 ICR male mice for 30 days. Weight gain and food efficiency ratio of the mice fed 5.0% extract of Rubus coreanus Miq. were significantly lower than those of the mice fed 0.5% extract Relative liver weight and activity of plasma alanine aminotransfernse were significantly increased only in the mice fed 5% extract of Atractylodes japonica Koidz. compared with the others. Splenocyte proliferation was not significantly different between the groups fed 0.5% or 5.0% extract of Rubus coreanus Miq. However, splenocyte proliferation was significantly decreased in the mice fed 5.0% extract of Atractylodes japonica Koidz. compared with that in the mice fed 0.5% Production of interleukin-2 by splenocytes from the mice fed 0.5% extract of Atractylodes japonica Miq. was significantly higher than the control value and it became lower with 5.0% dietary level. Secretion of $interferon-\gamma$ was not significantly different among groups. In conclusion, the defatted methanol extract of Atractylodes japonica Koidz. was likely to exert immunomodulating effect at the level of 0.5% but it may exert adverse effects on immune and liver functions at the level of 5.0%.

  • This study was designed to identify the effects of Reynoutria Japonica on antibacterial activity aganist Bordetella pertussis ATCC 9797 which is cause of whooping cough. The ethanol- and water-extracts of more than 80 oriental herbal medicine were Investigated by Kirby -Bauer method to determine their inhibitory effects on growth of B. pertussis ATCC 9797 in vitro. For that Reynoutria Japonica was selected. The ethanol-soluble extract of Reynoutria Japonica showed relatively high antivacterial activity against B. pertussis ATCC 9797. However, the water-soluble extract of Reynoutria Japonica showed no antibacterial activity. The ethanolic extract was further fractionated with organic solvents such as hexane, chloroform, and ethyl acetate, in that order. Among the fraction tested, the chloroform fraction showed the highest antibacterial activity when the ethanol-soluble extract of Reynoutria Japonica minial inhibitory concentration(MIC) was $25{\mu}g/m{\ell}l$. Results support a role far Reynoutria Japonica in inhibiting the cell growth of B. pertussis ATCC 9797, but further experimentation is required.
