Paragraph 0235-0237, (2017/11/16)
The invention discloses a preparation method of flavonoids. The method comprises the following step: in a solvent, in the presence of iodine and a silver salt or in the presence of iodine and a copper salt, performing an iodination reaction on a compound 1 to obtain a compound 2. Raw materials used in the method are easy to acquire, and the method has high yields and simple post processes, and does not need column chromatography.

, p. 1006 - 1010 (2007/10/02)
Kanzakiflavone-1 and -2, isolates from Iris Unguicularis, and their position isomers were synthesized to confirm the structures of the isolates.The differences among these flavones are discussed on the basis of spectral data.Keywords: kanzakiflavone-1; kanzakiflavone-2; 4',5-dihydroxy-7,8-methylenedioxyflavone; 6,7-methylenedioxy-4',5,8-trimethoxyflavone; 7,8-methylenedioxy-4',5,6-trimethoxyflavone; 3'-acetyl-4',5-dihydroxy-6,7-methylenedioxyflavone
