Abstract
From the root bark of Garcinia subelliptica, two new xanthones named subelliptenones C (1) and D (2) were isolated in addition to two known xanthones [12b-hydroxy-des-D-garcigerin (3) and globuxanthone (4)]. The structures were determined by analysis of nmr spectral data including 2D techniques.
