title: Phytochemical Evaluation of Roots of Polygonum viscosum Buch-ham.
abstract: Phytochemical evaluation of the chloroform extract of roots of Polygonum viscosum has yielded six compounds, stigmasterol, 7,4-dimethylquercetin, kaempferol, quercetin, myricetin and scutellarein. Among the six compounds isolated and characterized by chemical and spectral (UV, NMR and Mass) analysis in the present phytochemical evaluation, stigmasterol was not reported earlier from P. viscosum. The compounds, 7,4'-dimethylquercetin, quercetin and scutellarein were reported from P. hydropiper. Kaempferol from P. amphibium, P. aviculare, P. convolvulus, P. hydropiper, P. lapathifolium and P. persicari a and myricetin from P. aviculare and P. lapathifolium were also reported earlier. This appers to be the first report of the occurrence of all the six compounds from P. viscosum.
