|Title:||New C-methylated flavones from Elsholtzia blanda Benth|
|Abstract:||Three new C-methylated flavones, named as 5,5'-dihydroxy-7-acetoxy-6, 8,3", 3"-tetramethylpyran (3', 4')flavone 1,5, 5'-dihydroxy-7- (α-methyl)butyroxyl-6,8, 3", 3"-tetramethlpyran (3', 4')flavone 2 and 5, 5'-dihydroxy-6,7-methylenedioxy-8, 3", 3"-trimeth ylpyran (3', 4') flavone 3 have been isolated along with three known flavones from Elsholtzia blanda Benth (Chinese name "Sifanghao", Berberidaceae). Their structures have been deduced on the basis of their spectral data and chemical studies.|
