Abstract

Two new tetranortriterpenoids, trijugins A (1) and B (3), isolated from the leaves of Heynea trijuga (Meliaceae), have been shown to be derivatives of methyl angolensate but with a novel carbon skeleton having a contracted ring C. The structures were assigned on the basis of detailed ¹H and ¹³C nuclear magnetic resonance spectroscopic examination including 2D long-range δ_C/δ_H correlation and homonuclear ¹H nuclear Overhauser effect difference experiments.
