内容記述
Three phenylethanoid glycosides were isolated from a 1-butanol soluble fraction of a methanol extract of the fresh immature legumes of Tabebuia chrysotricha. These glycosides were identified to be 2-(3,4-dihydroxypheny1)ethy1 O-α-L-rhamnopyranosy1-(1 → 3)-(4-O-caffeoy1)-β-D-glucopyranoside (acteoside), 2-(3,4-dihydroxypheny1)ethy1 O-α-L-rhamnopyranosy1-(1 → 3)-(4-O-caffeoy1)-2-O-acety1-β-D-glucopyranoside (2'-acety1acteoside), and 2-(3,4-dihydroxyphenyl)ethy1 O-α-L-rhamnopyranosy1-(1→3)-(6-O-cafeoy1)-β-D-glucopyranoside (isoacteoside), respectively, by spectroscopic methods and chemical evidences.
