    Author: Yadava RN.
    Journal: Nat Prod Lett; 2001; 15(5):315-22. PubMed ID: 11841115.
    Abstract:
    A new biologically active triterpenoid saponin m.f. C42H68O13, m.p. 315 degrees-317 degrees C was isolated from the ethyl acetate soluble fraction of the methanolic extract of the leaves of Lepidagathis hyalina. Its structure was characterized as 3-beta-O-[alpha-L-rhamnopyranosyl(1-->4)O-beta-D-glucopyranosyl]16-alpha-hydroxy-olean-12-en(13)-28-oic acid by several spectral and chemical analysis. This new triterpenoid saponin showed antimicrobial activity against various plants pathogenic bacteria and fungi.
