  • One new triterpenoidal saponin, saponin F(2) has been isolated from the bark of Kalopanax pictum Nakai var. typicum (Araliaceae), together with one known saponin, kizuta saponin $K_{12}$ (1). On the basis of chemico-spectral evidences, the structure of 2 has been elucidated to be 3-O-${\beta}$-D-xylopyranosyl$(1{\rightarrow}3)$-${\alpha}$-L-rhamnopyranosyl$(1{\rightarrow}2)$-${\alpha}$-L-arabinopyranosyl-23-hydroxyolean-12-en-28-O-${\alpha}$-L-rhamnopyranosyl$(1{\rightarrow}4)$-${\beta}$-D-glucopyranosyl$(1{\rightarrow}6)$-${\beta}$-D-glucopyranosyl ester.

  • Three triterpenoid saponins were isolated from the methanol extract of the stem bark of Kalopanax pictum Nakai var. magnificum (Araliaceae). The structures of these saponins were identified as hederagenin 3-O-${\alpha}$-L-arabinopyranoside, hederagenin-3-O-${\alpha}$-L-rhamnopyranosyl$(1{\rightarrow}2)$-${\alpha}$-L-arabinopyranoside and 3-O-${\alpha}$-L-rhamnopyranosyl(1{\rightarrow}2)-${\alpha}$-L-arabinopyranosyl hederagenin 28-O-${\alpha}$-L-rhamnopyranosyl$(1{\rightarrow}4)$-${\beta}$-D-glucopyranosyl$(1{\rightarrow}6)$-${\beta}$-D-glucopyranosyl ester.

  • The roots of Cynanhum caudatum (Asclepiadaceae) have been used in folk medicine in Japan and China for the prevention and treatment of various geriatric diseases and also as a cardiotonic agent. Constituents of this plant have mainly been examined for glycosides: besides two steroidal alkaloids, gagaminine and gagamine which was firstly isolated by us, more than 35 polyoxypregnane glycosides and aglycones have also been identified. Gagaminine inhibits potently the hepatic aldehyde oxidase activity and lipid peroxidation in vitro. The present work deals with the comparison of antioxidative activities of gagamine, a new pregnane alkaloid, three isolated polyoxypregnanes containing a keto group at C-20 with those of gagaminine, a potent antioxidant, in order to explain the structure-activity relationships. The results of this study further prove that the cinnamoyl group of gagaminine is very important for the inhibition on the aldehyde oxidase activity while the nicotinoyl group is necessary for anti-lipid peroxidation. Besides that, the keto compounds having no ester group at C-12 were found to be more active than the others except gagaminine.

  • From the root of Angelica decursiva-albiflora Yook, which has been used as a folk medicine for a sedative, analgesic and expectorant, four free coumarins, e.g., decursidin(I), decursin(II), umbelliferone(III) and nodakenetin(IV), and two coumarin glycosides, e.g., nodakenin(V) and decuroside I(VI) were isolate. The cytotoxicity of nodakenin(V) against L-1210 leukemia cells was less effective than cisplatin, but in the nephrotoxicity against rabbit kidney proximal tubular cell nodakenin(V) showed remarkably less nephrotoxicant than cisplatin.

  • For the investigation of medicinal resource in Phyllanthus ussuriensis, the studies were conducted to evaluate the pharmaco-constituents in Phyllanthus ussuriensis, which is used as folk medicine in China. From the hot water extract of leaves, three phenolic compounds were isolated and identified as phloroglucinol, gallic acid and rutin by physico-chemical properties and spectroscopic evidences$(IR,{\;}^1H-NMR,{\;}^{13}C-NMR{\;}and{\;}Mass,{\;}etc.)$.

  • Chinese crude drug "Lu-ti-cao"(鹿蹄草) has been used as a remedy for beriberi, cut bleeding, snake bite, etc. In Korea, the drug is called "Nok Je Cho" and has been used as a folk medicine of the same effect as that of Chinese equivalent. The original plant of this drug has not yet been as certained. To clarify the botanical origin of "Nok Je Cho", the morphological and anatomical characteristics of the leaves of Pyrola species growing in Korea, i.e. P. incarnata, P. japonica, P. minor, P. renifolia, P. secunda were studied. As a result, it was clarified that "Nok Je Cho" was the leaf of Pyrola japonica and Pyrola minor.

  • Deer horn has been used in oriental medicine and folk remedy. It has had much effects on 'health and tonic efficacy' But this word, 'health and tonic efficacy', is very obscure in modern sense This report attempts to investigate their scientific and objective effects among many papers. The biochemical components of antler are composed of pentoses, hexoses, acid mucopolysaccharides, free and ester fatty acids, glycolipids, phospholipids, prostaglandins, sterols, protein and peptides, free amino acids, minerals, hormones etc. Deer horn extract especially increases body weight gain and feed efficiency, and it stimulates the ability of spermatogenesis of animal. However, a few papers have reported concerning the toxicity and side effects of antler.

  • Reactive oxygen species (ROS) are continuously produced at a high rate as a by-product obtained in the aerobic metabolism. A major portion of living organisms has defense system as superoxide dismutase or catalase against damage produced by ROS. Several lines of evidence provided that ROS appears to cause to develop aging and various diseases. Spatholobus suberectus Dunn has been known as a Korean folk medicine for promoting blood circulation and relieving blood stasis as anemia. In this study, we have investigated the antioxidant activities of Spatholobus suberectus Dunn in order to find the antioxidant substances from natural products. For various antioxidant experiment, the major antioxidant component was isolated from EtOAc extract of Spatholobus suberectus Dunn. This compound was identified as (-)-epicatechin by chemical and physical analysis.

  • Antihepatotoxic effect of dimethyl-esculetin, the major constituent of herbal drug Artemisia capillaris $T_{HUNBERG}$ (Compositae) which has long been used as folk medicine for gall stone and hepatitis in Asian country (China and Japan, except Korea) was investigated on the rabbit intoxicated with carbon-tetrachloride. Ten rabbits were divided into two parts, group A and B in five each. The group A was injected with carbon-tetrachloride, 0.1ml per kg at begining of the experiments for control. The group B was injected with carbon-tetrachloride soon after 7 days treatment of dimethyl-esculetin, 30mg per day. The results obtained in this experiment were as follows.: 1) Antihepatotoxic activity of dimethyl esuletin on the rabbits intoxicated with carbon tetrachloride has shown the serum glutamic oxaloacetic transaminase activity and serum glutamic pyruvic transaminase activity decreased respectively. 2) The component of Artemisia capillaris, dimethyl-esculetin, has shown remarkable antihepatotoxic effect.

  • Macrophages play an important role in host defense against tumors by killing tumor cells. Our work is directed toward studying the effect of the extracts of Salvia plebeia on induction of antitumor activity in macrophages, since it has been usezd as a folk-medicine for the treatment of hepatitis and tumors. The ability of macrophage treated with the plant extracts to inhibit the growth of tumor cells was assessed. The Extracts of the plant induced antitumor activity and could enhance the tumoricidal activity of macrophages when used in combination with $IFN-{\gamma}$. These results suggest that Salvia plebeia extract contain immunomodulatory factors responsible for the induction of the antitumor activity.
