Abstract

Two new C-15-acyl phragmalin limonoids, velutinalides A (2) and B (3), featuring a C-16/C-30 δ-lactone ring, and a new structurally related natural product, R310B8 (1), were isolated from the leaves of Chukrasia tabularis var. velutina. Their structures were elucidated on the basis of extensive spectroscopic data analyses and by comparison of their NMR data with those of related known compounds.

Key words

Maliaceae - Chukrasia tabularis var. velutina - C-15-acyl phragmalin limonoid - velutinalide
