Two new xanthones, 3-hydroxy-6-methoxy-5'-isopropyl-4',5'-dihydrofuro[2',3' : 7, 8]-6″,6″-dimethyl-4″,5″-dihydropyrano[2″,3″ : 1,2]xanthone (1) and 1,6-dihydroxy-7-methoxy-8-(3-methylbut-3-enyl)-6',6'-dimethyl-4',5'-dihydropyrano[2'3' : 3,2]xanthone (2), were isolated from the pericarp of Garcinia mangostana. Their structures were elucidated by spectral means (1-D and 2-D NMR, MS).
3-羟基-6-甲氧基-5'-异丙基-4',5'-二氢呋喃[2',3':7,8]-6″,6″-二甲基-4″,5″-二氢吡喃[2″,3″:1,2]紫檀烷酮（1）和 1,6-二羟基-7-甲氧基-8-(3-甲基-2-丁烯基)-6',6'-二甲基-4',5'-二氢吡喃[2'3':3,2]紫檀烷酮（2）。通过光谱手段（1-D 和 2-D NMR、MS）阐明了它们的结构。
