A new havanensin-type limonoid from Chisocheton macrophyllus

Abstract

A new havanensin-type limonoid, 16β-hydroxydysobinin (1), along with four known limonoids (2–5), have been isolated from the seeds of Chisocheton macrophyllus. The chemical structure of the new compound was determined by referencing spectroscopic data, and by comparison to those related spectra previously reported. Each compound was evaluated for its cytotoxic efects against Michigan Cancer Foundation-7 (MCF-7) breast cancer cells and display no signifcant activity
