Abstract:
One iridoid and 2 phenylpropanoid glycosides were isolated from the stem bark of S. kunthianum together with mixtures of β-sitosterol and β-sitosterol glucoside. Their structures were determined by IR, HRESIMS and 1D and 2D NMR experiments and their enzyme inhibitory effect evaluated using xanthine oxidase. The inhibitory activities of 6-O-trans-p-coumaroyl-decinnamoylglobularimin-Stereospermiside, (3, 4-dihydroxyphenyl) -ethyl-O- α-rhamnopyranosyl (1→ 3) -4-O cinnamoyl - β-D glucopyranoside and 1,6 di-O-cinnamoyl-β-D-glucopyranoside 1-3 were evaluated and compared to the standard positive control.
