Flavonoids from Limnophila indica.[Pubmed:17291552]
Phytochemistry. 2007 Mar;68(5):636-9.
Two flavonoids, (2S)-5,7,3',4'-tetramethoxyflavanone (1) and 5,7,2',5'-tetramethoxyflavone (2) together with three known flavonoids, 7-O-methylwogonin (3), skullcapflavone I (4) and 5-hydroxy-7,2'-dimethoxyflavone (5) were isolated from the whole plant of Limnophila indica. The structures of compounds 1-5 were elucidated on the basis of spectral and chemical studies.
