Abstract
Objective:
To make clear the chemical constituents of Uvaria grandiflora (Annonaceae).
Methods:
Purification was performed using sephadex LH-20 permeation and silica gel chromatography. Structures of the purified components were determined on the basis of 1H, 13C NMR analysis and also by comparison with those of authentic compounds.
Results:
Two major triterpenes, suberosol and lupeol, were identified.
Conclusion:
This paper is the first report on the identification of suberosol and lupeol from the gunus Uvaria.
