Abstract
Study the dichloromethane extract of the Garcinia cowa Roxb. ex Choisylatex collected in Phu Quoc - Kien Giang, we have isolated three tetraoxygenated
xanthones (1-3), namely cowagarcinone A (1), cowanin (2) and cowanol (3). The
structures of these xanthones were elucidated by analysis of spectroscopic data,
especially by 1D and 2D NMR as well as comparison with reported compounds in
the literature.
