Article

Finlaysonia obovata, a latex – exuding mangrove plant (Fam. Periplocaceae), is found in the tidal flats in India, Burma, and Malay, the leaves of which are reported to be eaten as salad in the Moluccas. Mangrove latex-bearing plants were found to show antibacterial and antiviral activity [1]. Earlier we have studied the antibacterial activity, performed the GCMS analysis of extracts, studied the lipids of the leaf, and isolated a rare antibacterial triterpene from F. obovata [2, 3]. The present paper deals with the antibacterial screening of column fractions of an active hexane extract, and isolation and spectral characterization of stigmast-4-en-3β-ol from leaves of F. obovata.

The antibacterial assay of the hexane extract of leaves of F. obovata was carried out against seven freshwater fish pathogenic bacteria (see Experimental) [ 3]. The hexane extract was found active against all except S. aureus and E. tarda. This extract was further taken up for fractionations and isolations of...
