Study on the isolation, structure elucidation 2 saponins and antibacterial, antifungal activities and cytotoxicity of saponins from roots of Momordica cochinchinesis Spreng, 4-5 years of age and collected at Tay Ninh in June 2002. Results: 2 saponins of oleanolic acid group were isolated and elucidated from BuOH extract of the root of Momordica cochinchinensis Spreng extraction were momordin Ib and momordin. Saponin's structure was determined by spectrum method and was compared with published data. The results showed that both of saponins have strong antibacterial to E.coli, B.subtillis, and S.aureus without cytotoxicity in the three experimental cell lines

components and biological properties of seed and root of Momordica cochinchinensis (Lour) spreng in Vietnam showed that: the content of lipid in seed nucleus is very high 56%, seed membrane 23%, root 1.73%. Alkaloid exists in seed nucleus, not exist in seed cover and root; tanin was much in seed nucleus and little in seed cover and root; glycoside was much in seed cover, root and little in seed nucleus; flavonoid was much in seed nucleus, little in seed cover and root; saponin was much in root and little in seed nucleus and seed cover. Saponin in Momordica cochinchinensis (Lour) spreng can inhibit different kinds of virus and microorganisms. Extracted material and solvent rate decided antivirus and antimicroorganism activities of saponin
