| Abstract: | A new flavanone, euchrenone a17 ( 1 ), along with eighteen known compounds, glabrol ( 2 ), euchrenone a2 ( 3 ), formononetin ( 4 ), 7‐methoxy‐2′,4′‐dihydroxyisoflavone ( 5 ), 3‐(3,4‐dimethoxy‐phenyl)‐7,8‐dihydroxy‐chromon‐4‐one ( 6 ), 5,7,2′‐trihydroxy‐4′‐methoxyisoflavone ( 7 ), 2′‐hydroxygenistein ( 8 ), euchrenone b1 ( 9 ), euchrenone b2 ( 10 ), euchrenone b16 ( 11 ), vanillin ( 12 ), p‐hydroxybenzoic acid ( 13 ), medicagol ( 14 ), octadecyl ferulate ( 15 ), (+)‐syringaresinol ( 16 ), β‐sitosteryl‐D‐glucoside ( 17 ), and a mixture of β‐sitosterol ( 18 ) and stigmasterol ( 19 ), were isolated from the methanolic extracts of the roots of Euchresta formosana. The structures of these compounds were established by means of spectral analysis. |
