【Abstract】 The fruit hull of mangosteen,Garcinia mangostana,has been used for many years as a medicine for treatment of skin infection,wounds and diarrhea.In the present study,1D 1H NMR,13C NMR,DEPT and 2D HMBC,HSQC,1H-1H COSY,ROESY methods were used to identify the structure of 1,3,6trihydroxy-7-methoxy-2,8-bis-(3-methyl-2-butenyl)-9-xanthenone α-mangostin extracted from the fruit hull of mangosteen.The 1H and 13C chemical shifts of α-mangostin were assigned.更多还原
