Abstract

A detailed close phytochemical investigation of the fruits of Ternstroemia cherryi led to the isolation and identification of the minor metabolite, ternstroenol F, which possessed the usual barrigenol-like terpenoid backbone. The notable difference was that this minor metabolite had the 2(E)-4(Z)-6(E)-decatrienoic acid forming an ester bond at C-22 of the oleanane backbone. Ternstroenol F was evaluated for its inhibitory effects on NO inhibition, cell viability and TNF- α release in RAW 264.7 macrophages, displaying an IC₅₀ values of 0.23, 0.81 and 1.84 µM respectively.
