| Abstract: | ??OBJECTIVE To study the chemical constituents of the ethyl acetate fraction from the stems of Saprosma merrillii Lo. METHODS The compounds were isolated and purified by silica gel column and Sephadex LH-20 column. Their structures were elucidated on the basis of chemical properties and spectral analysis. RESULTS Ten compounds were isolated and elucidated as 5-hydroxylmethylfuraldehyde(1), 3??-hydroxycholesta-5-ene(2), scopoletin(3), isoscopoletin(4), quercetin-3-O-glucoside-6??-gallate(5), 4??-hydroxy-7-methoxy flavanone(6), pinoresinol(7), N-trans-coumaroyltyramine(8), luteolin-7-O-B-D-glucopyranoside(9), and hypodiolide A(10). CONCLUSION All of the compounds are isolated from this genus for the first time except for compound 3 |
