Major separation for the active ingredients and characterization of chemical properties in conjunction with screening test on animal were performed in order to analyze and standardize Ligustici Rhizoma or Angelicae Tenuissimae Radix as an important oriental herbal medicine for antiphlogistic or an important oriental herbal medicine for antiphlogistic or an anodyne. Furthermore the structure, composition and contents of ingredients for essential oil in Angelicae Tenuissimae Radix(Suckpo, Korea) were determined by means of Ge/MS followed by screening test on Z-ligustilide(82%) known as major ingredient as well as butylidenephthalide collected by HPLC with normal phase semiprep-column. The total active ingredient in Ligustici Rhizoma from China or Angelicae Tenuissimae harvested at Choonyang(Kyungnam, Korea), Jungsun(Kangwon, Korea), Suckpo(Kyungnam Korea), Youngchun(Kyungnam, Korea) have been determined showing higher abundant for three times on the product in Korea compared to that in China. In addition, the major component in Ahgelicae Tebyussunae Radux extract was found to be Z-ligustilide(70-80%) which is very different from that in Ligustici Rhizoma senkyunolide(39%) as major species. For screening test of Ligustici Rhizoma or Angelicae Tenuissimae Radix extracts toward the target animal, the efficiency has been shown the similarity on both extracts. Taking into account the level of ingredient, the total efficiency may be three times higher on Angelicae Tenuissimae Radix in Korea compared to Ligustici Rhizoma in China. As a result of present study, it is preferable to distinguish between Ligustici Rhizoma and Angelicae Tenuissimae Radix for better usage of oriental herbal medicine because of very different composition and abundant in spite of their similar screening effect.

Cocos nucifera (C. nucifera) oil is indigenously used to treat cardiovascular diseases. However, coconut husk fibre (which is rich in polyphenols) has not been screened for this property. Based on the ethnomedicinal use of polyphenols in treating cardiovascular diseases, this study was carried out to evaluate the effects of polyphenols of C. nucifera husk fibre on selected cardiovascular disease indices in mice. Fifty adult male Swiss albino mice were assigned randomly into five groups (A-E). Mice in groups B, C, D and E were administered 31.25, 62.5, 125, and 250 mg/kg body weight polyphenols of ethyl acetate extract of C. nucifera husk fibre respectively while the control group (A) mice received 5% DMSO for seven days. The mice were sacrificed twenty four hours after the last administration of polyphenols. Heart and plasma lactate dehydrogenase (LDH), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities and plasma lipid profile were determined. Results revealed significant reduction (^*p< 0.05) in plasma levels of total cholesterol and LDL-cholesterol with no significant change (^*p> 0.05) in HDL-cholesterol, triglyceride and VLDL levels in the plasma at all doses of polyphenols administered compared to controls. There was significant reduction (^*p< 0.05) in the activities of heart AST and LDH while plasma ALT, AST, and ALP activities were not significantly altered (^*p> 0.05) at all doses of polyphenols administered compared to controls. These results suggest that the polyphenols of C. nucifera husk fibre possess cardio-protective properties and also indicate their possible use in the treatment of cardiovascular diseases.

Inner nutshell of Castanea mollisima BL (chestnut) has been used as an anti-aging and anti-wrinkle agent from the ancient time in east Asia. In order to develop new anti-aging and anti-wrinkle, ethanolic extract of inner nutshell of Castanea mollisima BL (Cor-285) was prepared and various biological activities were evaluated. Cor-285 showed potent antioxidant activity, Especially, Cor-285 possessed potent free radical scavenging activity in vitro (IC50:7.6 g/ml) compared to gallic acid (IC50:12.5 g/ml), Cor-285 showed the preventive effect against UV-induced cytotoxicity of fibroblast at concentration of 25-250 g/ml. When Cor-285 was evaluated for its anti-allergic activity, it effectively inhibited histamine release from mast cells induced by compound 48/80 (86% inhibition at 10 mg/ml). The inhibitory activity was stronger than that of glycyrrhiznate. Cor-285 also showed in vivo inhibition against delayed hypersensitivity as well as croton-oil induced ear edema in mice when topically applied These results strongly suggest that Cor-285 may reduce immunoregulatory 1 inflammatory skin trouble. From the attempts to isolate the constituents, citropten (simple coumarin) and ellagic acid, a well known radical scavenger, were isolated. In a clinical trial of twenty healthy volunteers with aged skin,6 weeks application of Cor-285 (3% cream) decreased wrinkle about 26% and increased moisturizing 20% on the skin. All of these results indicate that Cor-285 may be an effective anti-aging and anti-wrinkle agent.

This study was carried out to investigate the effects of Salvia plebeia R. Br. ethanolic extract with different aspects (stem/leaf and whole plant) on differentiation and lipid accumulation in 3T3-L1 preadipocytes. The morphological changes and the degrees of lipid accumulation in 3T3-L1 cells were measured by Oil Red O staining and intra-cellular triglyceride (TG) assay. The mRNA expressions of special peroxisome proliferation activated receptor- genes (PPAR), CCAAT/ enhancer-binding protein (C/$EBP{\alpha}$), fatty acid synthase (FAS) and lipoprotein lipase (LPL) were detected by reverse transcriptase polymerase chain reaction (RT-PCR). The 50% ethanolic extracts ($100{\mu}g/mL$) of stem and leaf (SALE) and 30% ethanolic extracts (100 g/mL) of whole plant (SAE) from Salvia plebeia R. Br. were significantly attenuated lipid accumulation during adipogenesis in 3T3-L1 cells. Ethyl acetate-soluble fractions ($50{\mu}g/mL$) significantly inhibited lipid droplet accumulation in 3T3-L1 cells. In addition, SALE induced down-regulation of specific adipogenic transcriptional factors (C/$EBP{\alpha}$ and $PPAR{\gamma}$) and target genes (FAS and LPL) during adipogenesis. Salvia plebeia R. Br. may be used as a safe and efficient natural substance to manage obesity.

This study was designed to measure taste sensitivity and the five basic senses by an educational classification instrument. The instrument was a rice kit that could use samples in a dry powder form or oil extract after long-term storage To test for taste, sucrose, salt, citric acid, and quinine sulfate were made at different concentrations and taste sensitivity was measured on a scale from level 1 to level 5. To obtain baseline data, an inspection tool for the five senses was used and randomly applied on 101 schoolchildren in the third and fourth grade in the city of Cheonan in Korea. The inspection tool was composed of 17 questions; 5 questions regarding visual characteristics and three questions each for characteristics regarding taste, hearing, smell, and touch. The average age of the schoolchildren was 9.5 years old and there were 49 third grade students (9 years of age), and 52 fourth grade students (ten years of age). There were slightly more male students than female students, 56 (55.4%) compared to 45 (44.6%), respectively. The average height of female students was higher than that of males, but the average BMI (body mass index) of the male students was slightly higher than that of female students (18.28 compared to 18.09, respectively). Female students were slightly more sensitive to salty tastes than male students (2.8 compared to 2.5, respectively). In the score distribution for each sense, touch sense was the highest at 7.59, sight sense was 7.49, hearing sense was 5.43, smell sense was 5.24, and taste sense was lowest at 3.69. Therefore, schoolchildren first tend to recognize and deem important the touch and sight of food before its taste.

A Bacillus strain which produces ${\beta}-galactosidase$ with high transgalactosylation activity, was isolated from soil and tentatively designated as Bacillus sp. A1. When ${\beta}-galactosidase$ from Bacillus sp. A1 reacted with 40% (w/w) lactose, transgalactosylation ratio reached up to 90% at the 70% conversion of the initial lactose. The biosynthesis of the enzyme in Bacillus sp. A1 required lactose as an inducer and was repressed by glucose. Observing that the addition of amino acids to culture medium resulted in enhancing, to a significant extent, both the growth and the enzyme production of the strain, yeast extract and commercially available hydrolysates of protein were examined for the suitability as amino acid source. As it turned out, SMP, an enzymatic hydrolysis product of soybean protein from Fuji Oil Co.(Japan), was the most suitable for optimization of the culture medium. When Bacillus sp. A1 was cultured in the presence of 0.5% SMP and 2% lactose, the enzyme activity increased up to $1.8\;U/m{\ell}-broth$.

Obesity, which is characterized by excessive fat accumulation in adipose tissues, occurs by fat absorption by lipase and sequential fat accumulation in adipocyte through adipocyte differentiation. Thus, inhibition of pancreatic lipase activity and adipocyte differentiation would be crucial for the prevention and progression of obesity. In the present study, we attempted to evaluate anti-adipogenic activity of several algae extracts employing preadipocytes cell line, 3T3-L1 as an in vitro assay system. The effects on pancreatic lipase activity in vitro were also evaluated. Total methanolic extracts of Cladophora wrightiana and Costaria costata showed significant inhibitory activity on adipocyte differentiation as assessed by measuring fat accumulation using Oil Red O staining. Related to pancreatic lipase, C. wrightiana and Padina arborescens showed significant inhibition. Further fractionation of C. wrightiana, which showed the most potent activity, suggested that $CHCl_3$ and n-BuOH fraction are responsible for adipocyte differentiation inhibition, whereas n-BuOH and $H_2O$ fraction for pancreatic lipase inhibition. Our study also demonstrated that n-BuOH fraction was effective both in early and middle stage of differentiation whereas $CHCl_3$ fraction was effective only in early stage of differentiation. Taken together, algae might be new candidates in the development of obesity treatment.

Sebum is secreted due to the effect of androgen, which start to be secreted at puberty. Androgens have profound effects on the physiology of the sebaceous gland, Using the human sebocyte cell line SZ95, we investigated the inhibitory effect of Chelidonii Harba (CH) on the subum production. Our results showed that numerous cytoplasmic lipid droplets were examined by Oil red staining and lipid droplets were increased markedly by testosterone. Cell viability was dose-dependently decreased by CH as compared with untreated cells, while total lipid content and cholesterol slightly were increased by CH. Testosterone significantly stimulated the synthesis of total lipid and the synthesis of specific sebaceous lipids such as cholesterol and triglyceride. Combined treatment with CH and testosterone resulted in a lower lipid synthesis than with testosterone alone. Especially cholesteol content was reduced by combined treatment with CH and testosterone. These results indicate that CH inhibits the testosterone-induced lipid synthesis in SZ95 cells and acts antagonistically to androgen at the cellular level.
