Cissus quadrangularis L. variant I (Family: Vitaceae), the common variant with square stem is widely used for peptic ulcer disorders (PUD) in traditional medicine. Aerial parts were collected during flowering and vegetative seasons and analysed. Aqueous (hot and cold) and solvent extracts (acetone, chloroform and ethanol) were screened for their anti-Helicobacter pylori (Hp) activities. Among them chloroform extract was observed to recover bioactive principles markedly with low minimal inhibitory concentration (MIC) and minimal lethal concentration (MLC). MIC was $30\;{\mu}g$ in both samples and MLC was $35\;{\mu}g$ for vegetative and $30\;{\mu}g$ for flowering seasons, respectively. Extracts from samples collected during flowering season were better than thse of vegetative season.

For the investigation of medicinal resources the studies were carried out to evaluated the pharmaco-constituents in the Leaves of Parthenocissus tricuspidata(Vitaceae), of which leaves have been used in Korea as folk remedies for the treatments of arthritis, jaundice, toothache, neuralgia, and etc. From 1-butanol fraction of the MeOH extract, Compound I ($C_{21}H_{18}O_{13}$, Quercetin-3-O-$\beta$-D-glucuronopyranoside), Compound II ($C_{21}H_{20}O_{12}$, Quercetin-3-O-$\beta$-D-glucopyranoside) and Compound III ($C_{25}H_{28}O_{12}$, Quercetin-3-O-(6"-n-butyl)-$\beta$-D-glucuronopyranoside) were isolated by column chromatographic separation using Sephadex LH-20 and ODS gel. Their structures were elucidated through instrumental analyses, such as $^{1}H$-NMR, $^{13}C$-NMR, IR, UV, El-Mass, FAB-Mass and GC. Especially compound III was Flavonol glycoside and named parthenosin.

The caffeic acid, 4-O-$\beta$-D-glucopyranosyl caffeic acid, 4-O-$\beta$-D-glucopyranosyl-$\rho$-coumaric acid and 7-O-$\beta$-D-glucuronide of ($\pm$)-eriodictyol have been isolated from the root of Vitis thunbergii var. sinuata. The structures of compounds were determined by chemical and spectroscopic methods.

As a part of our ongoing research to discover novel monamine oxidase (MAO) inhibitors of plant origin, we found that a MeOH extract from the whole plant of Cayratia japonica (Vitaceae) strongly inhibited the MAO activity in mouse brain. The EtOAc-soluble fraction was. therefore, subjected to the bioactivity-guided fractionations to isolate the active compounds. (omitted)

A new natural product, tetrastigmol A (1), and several known compounds as flavonoids (2 - 8), steroids (9 - 10), bergenin and its derivative (11 - 12), stilbens (13 - 15), lignan (16), benzenecarboxylic derivative (17) and two norisoprenoid (18 - 19) were isolated from the stem of Tetrastigma erubescens Planch. (Vitateae). Their structures were determined on the basis of NMR spectroscopic data. This is the first report on chemical constituents of this plant. Compounds 1, 6 - 8 and 12 - 15 showed strong antioxidant activity using two methods including DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging and lipid peroxidation inhibitory assays.

The complex analysis of male reproductive system of vines and fruit-tyees growing in zone of the Armenian Nuclear Power Plant (ANPP) is realized. The obtained data demonstrate that the homogeneous pollen with high fertility and optimal morphometric parameters in all variants is formed. The obtained results demonstrate that there is no one-sided effect of ANPP on the development and formation of investigated male generative system of vines and fruit trees. Thus, on the base of obtained results we can't confirm its deleterious effect on the environment.

The plants medicinal resourees of Mt. Joghe were investigeted 10 times from January, 1988 to October, 1988. In order to analyze the vegetation of Joghemountain area, herb plants structure and distribution. Herb plants of Joghe moun-tain consisted of 102 families, 265 species in all. The resources of important herbdrugs were Gramineae, Cyperaceae Oleaceae, Araceae, Polygonaceae, Caryophyllaceae,Ranunculaceae, Theaceae, Cruciferae, Liliaceae, Rosaceae, Geranjaceae, Violaceae,Vitaceae, Umbelliferae, Labiatae, Solanaceae, Campanulaceae, Rutaceae, Compositae,Dioscoreaceae, Fagaeeae, Moraceae, Anacardiaceae, Legum inosae, Cupressaceae, andJuelandaceae. The herb drugs were comparatively more than in other mountains inour country.

Korean folk medicine 'MeoRuIp' has been used to cure cough, rheumatism and abdominal pain after child birth. There has been no pharmacognostical confirmation on the botanical origin of the crude drug. To clarify the botanical origin of 'MeoRuIp', the morphological and anatomical characteristics of the leaves of Vitis and Ampelopsis species growing in Korea, i.e. Vitis amurensis, V. amurensis forma. glabrescens, V. flexuosa, V. thunbergii var. sinuata and Ampelopsis brevipedunculata var. heterophylla were studied. As a result, it was clarified that 'MeoRuIp' was the leaf of Vitis amurensis and Vitis flexuosa.

Cell cultures of Cayratia trifolia (Vitaceae), a tropical lianas, were maintained in Murashige and Skoog's medium containing $0.25mg\;1^{-1}$ NAA, $0.2mg\;1^{-1}$ kinetin and casein hydrolysate $250mg\;1^{-1}$. Cell suspension cultures of C. trifolia accumulate stilbenes (piceid, resveratrol, viniferin, ampelopsin), which on elicitation by any of $500{\mu}M$ salicylic acid, $100{\mu}M$ methyl jasmonate, $500{\mu}M$ ethrel and $500mg\;1^{-1}$ yeast extract, added on the 7th day, were enhanced by 3- to 6-fold ($5-11mg\;1^{-1}$) by the 15th day.
