摘要：

From the water-soluble portion of the methanol extract of stems of Ficus tikoua Bur., a new benzofuran glucoside, named 6-carboxyethyl-5-hydroxybenzofuran 5-O-beta-D-glucopyranoside (1), together with one known benzofuran glucoside (2) were isolated. Their structures were elucidated by 1D and 2D (H-1-H-1 COSY, HMQC, and HMBC) NMR spectroscopy and HRMS techniques. The antioxidant activities of the isolated compounds were assayed based on the scavenging activities of DPPH free radical. Compounds 1 and 2 exhibited moderate antioxidant activities, and the IC50 values were 242.8 mu g.mL(-1) and 324.9 mu g.mL(-1), respectively.
