Phenolic compounds from Caesalpinia minax

MA Rui,jing, YANG Xun,yun, WANG Ji,hua, TANG Hong,bo, WANG Li,qin*

[Abstract] Fifteen compounds were obtained from the twigs and leaves of Caesalpinia minax. Their structures were identified as apigenin ( 1), 5,7,3′,4′, tetrahydroxy,3,methoxyflavone( 2), luteolin,5, 3′,dimethyl,ether ( 3), thevetiaflavon ( 4), apigenin,7,O,β,D,glucuronide ( 5), bonducellin ( 6), 7,hydroxy,3,(4,hydroxybenzylidene),chroman,4,one ( 7), 3,deoxysappanchalcone ( 8), 5,acetonyl,7,hydroxy,2,methyl chromone ( 9), 4,(trans),acetyl,3,6,8,trihydroxy,3,methyl,dihydronaphthalenone ( 10), 4,(cis),acetyl,3,6,8,trihydroxy,3,methyl,dihydronaphthalenone ( 11), vanillic acid ( 12), ω,hydroxypropioquaiacone ( 13), syringaresinol ( 14) and uracil ( 15). All compounds were isolated from C. minax for the first time. Compounds 1,14 were phenolic compounds and compounds 1,5, 9,13 and 15 were isolated from the genus Caesalpinia for the first time.
