5,9,11-Trihydroxy-2,2-dimethyl-10-(3 0 -methyl-2 0 -butenyl)-3-(2”-methyl-3”-butenyl)- pyrano[2,3-a]xanthen-12(2H)-one (1) was isolated from the stem bark of Calophyllum pseudomole. The structure of 1 was established by spectroscopic analysis which included UV, IR, HRESIMS and NMRexperiments. Abstra...
