C-Glycosylflavonoids. The chemistry of orientin and iso-orientin.

摘要: 1. The structures of orientin and iso-orientin have been investigated by periodic acid ferric chloride oxidation the tetra-O-methyl derivatives identification products oxidation. 2. preparation properties 3‣,4‣,7-trimethyl ethers are described, nuclear-magnetic-resonance spectra orientin, their tri- discussed. 3. Orientin formulated as 8- 6-C-beta-d-glucopyranosyl-luteolin respectively.
