  • This study was attempted to investigate the effect of Gardeniae Fructus on GOT, GPT, Al.p, LDH activities and level of total cholesterol in serum of $CCl_{4}$ and $_{D}-galactosamine$ intoxicated rats, and bile excretion. The geniposide and extract caused a remarkabel decrease of GPT activities, level of total cholesterol in serum of $CCl_{4}$ intoxicated rats at EtOH Ex. 300, 500 mg/kg p.o., MeOH Ex. and geniposide 100 mg/kg p.o., and GOT, Al.p, LDH activities were significantly decreased compared with control group. It caused a remarkable decrese of GPT, Al.p, LDH activities in serum of $_{D}-galactosamine$ intoxicated rats, and GOT activities was significantly decreased compared with control group. The geniposide and extract caused a remarkable increase of bile excretion, when administration of EtOH extract 500 mg/kg p.o., MeOH extract 100 mg/kg i.d., MeOH extract 50 mg and geniposide 50 mg/kg i. v. compared with normal-control group.

  • We have conducted to characterize the physico-chemical change and pharmacological transformation of traditional herbal medicines by means of processing. Processed Gardeniae Fructus was prepared by heating of fruit of Gardenia jasminoides(GF) for $30{\sim}50\;minute$ in the roster designed for herb processing. The contents of drying loss, water extract, diluted ethanol extract, ether extract and geniposide in non-processed GF and processed GF were examined. The contents of drying loss, water extract and geniposide in processed GF showed a decrease as compared with those of non-processed GF, however the contents of dilute ethanol and ether extract showed a increase as compared with those of non-processed GF. The rate of decrease/increase of those index were in proportion to heating time. And, biological activities of methanol extract of non-processed GF and processed GF were investigated. DPPH scavenging effects and inhibitory effect of xanthine oxidate and hemolysis of processed GF exhibited more effective than those of non-processed GF in vitro. Accelerating effect of large intestinal transport and purgative action of non- processed GF were discriminated by processing of GF. Methanol extracts of non-pro- cessed GF and processed GF showed the protective effects against the hepatotoxicity induced by ${\alpha}-naphthylisothiocyanate$ in rats. These results suggested that the transformation of biological activities of GF by means of processing may be due to the physico-chemical change of the constituents in GF by heating.

  • The fructus of Gardenia jasminoides Ellis (GF) has been widely used as a natural colorant in Asian countries, and also as a Chinese traditional medicine for its homeostatic, antiphlogistic, analgesic, and antipyretic effects. In the present study, its main component, crocin, was fermented with lactic acid bacteria (LAB) and their antihyperlipidemic activity was measured. The GF extract, fermented GF (F-GF), crocin, and fermented crocin (F-crocin) significantly inhibited the increase of serum triglyceride (TG) level in corn oil feeding-induced triglyceridemic mice, as well as that of serum TG and total and LDL cholesterol levels in Triton WR-1339-induced hyperlipidemic mice. These agents also showed hypolipidemic activity in hyperlipidemic mice induced by high fat diet for 5 weeks. F-GF and F-crocin exhibited more potent hyperlipidemic effects than GF and crocin. The results suggest that the hypolipidemic effect of GF and crocin can be synergistically activated by LAB, and that F-GF and F-crocin may improve hyperlipidemia in clinic, compared with GF and crocin.

  • 추출용매를 달리하여 마이크로웨이브로 추출한 치자의 생리활성을 측정하였다. 치자를 물, 50% 및 100% 에탄올을 용매로 하여 마이크로웨이브로 추출하였고, 이의 생리활성을 측정하였다. 세 종류의 추출용매 중 50% 에탄올 추출구의 생리활성이 다른 추출구에 비해 높은 경향이었으며 100% 에탄올 추출구의 활성은 낮은 편이었다. 전자공여능은 0.6 mg/mL 농도일 때 50% 에탄올 추출물의 활성이 $96.43{\pm}0.25%$로 0.1, 1% L-ascorbic acid와 유사한 활성이 있었고, 아질산염 소거능은 $71.99{\pm}3.71%$로 0.1, 1% L-ascorbic acid에는 못 미쳤지만 0.01% L-ascorbic acid보다 우수한 활성이 있었다. 티로시나아제 저해활성은 $11{\sim}19%$로 모든 추출물에서 20% 미만의 낮은 활성을 보였고 물과 50% 에탄올 추출구는 농도에 반비례하여 활성이 증가하는 양상이었다. SOD 유사활성도 티로시나아제 저해활성과 유사한 결과로 모든 추출구가 농도 증가에 따라 활성이 감소하였으며 전체적으로 40% 미만의 활성이 있었다. 결론적으로 치자 추출물은 SOD 유사활성 및 티로시나아제 저해 효과는 높지 않지만 우수한 전자공여능과 아질산염 소거능이 있는 것으로 판단되므로 천연 항산화제로서 이용될 수 있는 가능성이 있었다.

  • Disturbance of antioxidant system is very common in chronic alcoholics and herbal or natural products with antioxidant activity have been used for its treatment. This study was to investigate the effect of Vitis vinifera extract(V), Schisandra chinensis extract(S), Taraxacum officinale extract(T), Gardenia jasminoides extract(G), Angelica acutiloba extract(A) and Paeonia japonica extract(P), and their combinations on the antioxidant and ethanol oxidation system. Male Sprague-Dawley rats were subjected to Lieber-DeCarli ethanol liquid diet(ED) and were then given different herbal extract mixtures for 6 weeks including VST(V 100+S 150+T 150mg/kg/day), VSG(V 100+S 150+G 150mg/kg/day), VTG(V 100+T 150+G 150mg/kg/day), and VAP(V 100+A 150+P 150mg/kg/day). When the activity of alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH) were compared between ED only group and herbal extracts treatment group, the differences were statistically significant. Phase I and II(glutathione-S-transferase, phenol sulfatransferase) enzyme activities were found to be significantly higher in the VAT treatment group compared to the ED group. Herbal extracts not only repressed the ethanol-induced elevation of malondialdehyde level, but also protected against ethanol-induced decrease in glutathione content, glutathione reductase, glutathione peroxidase, catalase and superoxide dismutase activities. The administration of the herbal extracts was found to be effective in eliminating lipid-peroxides induced by long-term consumption of alcohol by activating various enzyme systems and physiological active compound formation system. After a chronic consumption of alcohol, Angelica Radix protected the liver via activating the ethanol-metabolism enzyme system, and Paeoniae Radix via activating the ethanol-metabolism enzyme and the phase I, II-metabolism enzyme system. Taraxaci Herba was also effective in liver protection via activating the ethanol-metabolism enzyme system and the phase I, II-metabolism enzyme system, Gardeniae Fructus via activating the phase II-metabolism enzyme system and the anti-oxidation system enzyme, and Schisandra Fructus and a grapestone via activating the anti-oxidation system. Our data suggest that these herbal extracts may be useful as a health functional food or new drug candidate for fatty liver and hepatotoxicity induced by chronic alcohol consumption.

  • 천연식품보존료 개발 목적의 일환으로 항균효력이 있을 것으로 추정되는 한약재 중에서 목단피, 황백, 연교, 오미자, 자초, 길경 등 20종을 대상으로 물과 95% 에탄올로 항균성물질을 추출하여 각종 미생물에 대한 항균력을 검토하였다. 물 추출물의 경우, 모든 세균에 대하여 증식억제 효과가 나타난 것은 치자, 구기자, 오미자 등의 3종이었으며, 그중에서 오미자가 증식 억제력이 제일 강하였다. 에탄올 추출물의 경우, 대부분의 세균에 대하여 증식억제 효과가 나타난 것은 치자, 오미자, 자초 등의 3종이었으며, 목단피, 황백, 금은화 등의 3종은 그람양성균에만 효과가 나타났는데, 특히 황백의 경우, S. aureus에 대하여는 0.01%의 첨가로 균의 증식이 억제되었다. 한편 이들 한약재들의 물 추출물은 진균류에 대해서는 증식억제 효과가 좋지 않았으나, 에탄올 추출물의 경우, 목단피, 황백, 치자, 자초 등의 4종이 증식억제 효과가 우수하였고, 그중 황백이 균증식 억제력이 제일 강하였다. 전 시료를 통하여 에탄올 추출물이 물 추출물 보다 $2{\sim}100$배나 항균력이 높았으며, 특히 자초의 에탄올 추출물은 맛과 향 등의 관능검사결과 이미 이취가 적을 뿐만 아니라 항균력도 우수하여 천연식품 보존료로서 이용 가능성이 높았다.
