“…On preliminary screening, the extract showed the positive Liebermann-Burchard reaction for steroids and posi- tive Noller test for triterpenoids (Noller et al, 1942), which were confirmed by thin layer chromatography study (Stahl, 1969). Further separation of the specific phytochemical is in progress.…”

“…The extract tested positive for steroids (Liebermann, 1885), triterpenoids (Noller et al, 1942) and lipids (Trease and Trease, 1972). The extract was examined separately on silica gel G plates using the upper organic phase of the mixture: benzene:ethyl acetate:water (84:16:50).…”

S u m m a r y β-sitosterol and two triterpenoids: ursolic acid acetate and platanic acid have been isolated from ethanolic extract of Vitex trifola leaves. β-sitosterol was previously isolated from the leaves, stem and seeds of Vitex trifolia. Ursolic acid acetate has been isolated for the first time in this plant species. Platanic acid has been reported for the first time in Vitex trifolia and even in the family of this plant: Verbenaceae. These compounds were characterized using spectroscopic methods including 1D-1 HNMR, 13 CNMR, ESIMS and 2D-NMR (HSQC, HMBC, COSY) experiments and confirmed by comparison of their NMR data with those from the literature. A preliminary molluscicidal test for ethanol, chloroform and n-hexane extracts of leaves of Vitex trifolia against Biomphalaria alexandrina adult snails showed that ethanol extract of leaves with LC 50 value 26.42 mg/l (27.92 mg/l -24.99 mg/l) was more effective than n-hexane extract with LC 50 value 35.48 mg/l (43.81 mg/l -28.72mg/l) and chloroform extract with LC 50 value 46.77 mg/l (53.59 mg/l -43.81 mg/l) after 24 h exposure.
