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'-trimethoxyflavone (4), have been isolated from Polygonum viscosum. The structures of these compounds were elucidated by spectroscopic analyses, notably UV, MS and NMR.
