Abstract��
OBJECTIVE To study the chemical constituents of the root of Anemone tomentosa. METHODS The chemical constituents were isolated and purified by silica gel��Sephadex LH-20 column and thin-layer chromatography. Their structures were elucidated by spectral analysis and physico-chemical properties. RESULTS Eight non-alkaloid compounds were isolated and identified as 4��5-dimethoxyl-7-methylcoumarin(1��4��7-dimethoxyl-5-methyl coumarin(2��betulinic acid(3��oleanolic acid(4��oleanolic acid 3-O-��-L-arabinopyranoside(5��oleanolic acid 3-O-��-D-galactopyranosyl-(1��3-��-D-glucopyranoside(6��hederagenin 3-O-��-L-arabinopyranoside(7and 18-hydroxyursolic acid(8. CONCLUSION Five compounds except 1��2 and 4 were obtained from A. tomentosa for the first time. Compounds 6-8 were isolated from Anemone genus for the first time.
