Chemical constituents of leaves and fruit of Antidesma ghaesembilla Gaertn.

Abstract

Chemical investigation of the dichloromethane extracts of Antidesma ghaesembilla Gaertn. has led to the isolation of β-friedelinol (1), lupeol (2), squalene (3), polyprenol (4), β-sitosterol (5), long-chain hydrocarbons (6) and chlorophyll-a (7) from the leaves and β-sitosterol (5) and triacylglycerols (8) from the fruit. The structure of β-friedelinol (1) was elucidated by extensive 1D and 2D NMR spectroscopy, while those of compounds 2 to 8 were identified by comparison of their NMR data with literature data.
