3-Hydroxy-8,14-secogammacera-7,14-dien-21-one: A New Onoceranoid Triterpenes from <em>Lansium domesticum</em> Corr. cv <em>kokossan</em>

Abstract

A new onoceranoid triterpenes, namely 3-hydroxy-8,14-secogammacera-7,14-dien-21-one (1), has been isolated from the fruit peels of Lansium domesticum Corr. cv kokossan. The structure of 1 was determined on the basis of spectroscopic data including infrared, 1D and 2D-NMR, as well as high resolution mass spectroscopy analysis. Compound 1 showed a weak activity against MCF-7 breast cancer cell lines.
