Chemical constituents from Canarium pimela fruits

Objective: To investigate the chemical constituents from Canarium pimela fruits. Methods: Compounds were obtained after separation and purification by silica gel and Sephadex LH-20. The structures were identified on the basis of physico-chemical properties and spectrum data. Results: Eight compounds were isolated from Canarium pimela fruits. The structures were identified as amentoflavone(1),kaempferol-3-O-β-D-galactopyranoside(2),shikimic acid(3),quercetin(4),kaempferol(5),3,3 ’-di-O-methylellagic acid(6),3,3’,4-tri-O-methylellagic acid(7) and stigmasterol(8). Conclusion: Compounds 1 ~ 8 are isolated from Canarium pimela fruits for the first time.
