title: A new naphthoquinone from Polygonum aviculare.
abstract: A new naphthoquinone, 6-methoxyplumbagin was isolated from the acetone extracts of Polygonum aviculare. Its structure was elucidated by various spectroscopic methods. The known compounds sitosterol, oleanolic acid and 5,6,7,4'-tetramethoxyflavanone were also obtained from this natural source.
