Chemical constituents from Stauntonia brachyanthera Hand–Mazz

Abstract The present phytochemical investigations of Stauntonia brachyanthera Hand–Mazz resulted in the isolation of a triterpenoid glucoside (3-O- α - l -arabinopyranosyl-Akebonic acid, 1), four phenylpropanoids (staunoside C, cyclo-olivil-9-O- β - d -glucopyranoside, ficuscarpanoside B, ficuscarpanoside A, 2 – 5 ), three phenylethanoid glycosides (2-(3,4-dihydroxyphenyl)ethyl- β - d -glucopyranoside, 1′- O -phenethyl- α - l -rhamnopyranosyl-(1 → 6)- β - d -glucopyranoside, calceolarioside B, 6 – 8 ), a phenolic glycoside (seguinoside K, 9 ) and a chlorogenic acid analogue (methyl chlorogenate, 10 ). Among them, compounds 1 , 2 are isolated for the first time from this plant, compound 8 is firstly reported from genus Stauntonia and compounds 4 – 7 , 9 and 10 are new for the family of Lardizabalacea. The chemotaxonomic importance of these compounds was also summarized.
