Abstract
A new sesquiterpene, 1.4-dimethoxycarbonyl-7-(1-methylethyl)-3,3a,6,7,8,8a- hexahydroazulene (viscoazucine) (1), and a known flavone, 3',5,7-trihydoxy- 3,4',5'-trimethoxyflavon (4), have been isolated from Polygonum viscosum. T he structures of these compounds were elucidated by spectroscopic analyses, notably UV, MS and NMR.
