Abstract:
Two new xanthones have been isolated from the EtOAc extract of the roots of Premna microphylla Turcz. Based on spectral and chemical evidences, their structures were elucidated as 1-hydroxy-2,3-methylenedioxy-6-methoxycarbonyl-7-acetylxanthone 1 and 1,3-dihydroxy-2-methoxy-6-methoxycarbonyl-7-acetylxanthone 2. This is the first report on isolation of xanthones from this plant.
