Abstract
Two new benzofurans, gymnefuranols A (1) and B (2), together with six known furanolignans (3–8), were isolated from Gymnema tingens. The structures of the new compounds were elucidated by comprehensive analysis of the NMR and HR-MS data. Compounds 1, 2, 6, and 7 showed hepatoprotective activities against D-galactosamine-induced HL-7702 cell damage.
