Chemical Constituents of Schisandra propinqua(Wall.) Baill var. intermidia A.C.Smith

OBJECTIVE To study the chemical constituents in the Schisandra propinqua(Wall.) Baill var. intermidia A.C.Smith. METHODS The compounds were isolated and purified by using many kinds of chromatography, and their structures were identified according to the physical and chemical constants and spectral data. RESULTS Fifteen compounds were isolated and identified as 3（R）, 4（R）-epoxy-5（R）-hydroxy-1-cyclohexene-1-carboxylic acid (1), n-butyl-β-D-fructopyranoside (2), （+）-catechin (3), 3′,5′,7-trihydroxyflavanone (4), robtin (5), dihydrobinetin (6), robinetin (7), 2′,3,4,5,5′,7-hexahydroxy dihydrochalcone (8), butein (9), lignoceric acid-2,3-dihydroxy- propanenyl ester (10), melissic acid (11), daucosterol (12), 3-β-hydroxy-5α,8α-epidioxyergosta (13), kadsulactone (14) and β-sitosterol (15). CONCLUSION All these compounds have been obtained from Schisandra propinqua for the first time except the compound 14.
