| Summary: | Extensive work on the isolating of secondary metabolites from Malaysian
flora, root barks Garcinia mangostana was chosen for further phytochemical
analysis. This plant was going for detail separation work which involves extraction
and isolation of chemical component using a various techniques of analysis.
Xanthones was found as a major component from the isolation of this plant. Detail
work on the hexane extract of Garcinia mangostana has afforded two known
xanthones, a-mangostin and osajaxanthone. These pure compounds were elucidated
by using numerous spectroscopic analysis, such as ID and 2D NMR, MS, IR, UV and
also by comparison with the previous data.
