A new phenylpropanoid glycoside, brandioside, was isolated from Brandisia hancei. Its structure, [beta-(3',4'-dihydroxylphenyl)-ethyl]-(2-O-acetyl)-(3,6-O-di-alpha -L-rhamnopyranosyl)-(4-O-caffeoyl)-beta-D-glucopyranoside, was established by chemical and spectroscopic methods.
Brandisia hancei is a medicinal herb in China. The ethanol extract of this plant and four phenylethanoid glycosides, acteoside (1), 2'-acetylacteoside (2), poliumoside (3) and brandioside (4), isolated from it were shown to have inhibitory effects on free radical-induced hemolysis of red blood cells
In our continuing efforts to identify effective naturally sourced agents for diabetic complications, five caffeoylated phenylpropanoid glycosides, acteoside (1), isoacteoside (2), poliumoside (3), brandioside (4), and pheliposide (5) were isolated from the 80% EtOH extract of Brandisia hancei stems
Xanthine oxidase is a key enzyme associated with the incidence of hyperuricemia-related disorders. Repeated chromatography of the enzyme inhibitory part of the water extract of the twigs and leaves of Brandisia hancei (Scrophulariaceae) gave a flavone luteolin, an iridoid glycoside mussaenoside, two
The present study describes the isolation and purification of acteoside, 2'-acetylacteoside, poliumoside and brandioside, four phenylethanoid glycosides from Brandisia hancei. We examined their effects on the proliferation of cultured A7r5 rat aortic smooth muscle cells. The proliferative response
In our continuing search for novel antiangiogenic agents, a new lignan glycoside, (7R,8R)-1-(4-O-β-d-glucopyranosyl-3-methoxyphenyl)-2-{2-methoxy-4-[1-(E)-propene-3-ol]-phenoxyl}-propane-1,3-diol (1), along with three known lignans (2-4), were isolated from the 80% EtOH extract of Brandisia hancei
