To study new natural products, we used ODS (YMC, Kyoto, Japan) and silica gel column chromatography to separate compounds in Cercis chinensis Bunge (Leguminosae). A new stilbene, trans ‐3, 5, 3′, 4′‐tetrahydroxy‐4‐methylstilbene ( 1 ), along with 10 known compounds, namely piceatannol ( 2 ), dihydromyricetin ( 3 ), catechin ( 4 ), dihydrorobinetin ( 5 ), menisdaurin ( 6 ), lithospermoside ( 7 ), teatannin ( 8 ), dasycarponin ( 9 ), β‐sitosterol ( 10 ), and daucosterin ( 11 ), was isolated from C. chinensis. Their structures were elucidated on the basis of spectroscopic evidence. Compounds 2–6 and 9 were isolated from the genus Cercis Linn. for the first time. (Managing editor: Wei)
