Anti-oxidative and anti-inflammatory curcumin-related phenolics from rhizomes of Curcuma domestica
摘要:
Two new natural phenolics were isolated from the rhizomes of Curcuma domestica along with four known curcuminoids. The structures of the former were determined to be 1,5-bis(4-hydroxy-3-methoxyphenyl)-penta-(1E,4E)-1,4-dien-3-one and 1-(4-hydroxy-3-methoxyphenyl)-5-(-4-hydroxyphenyl)-penta-(1E,4E)-1,4-dien-3-one, respectively, by spectral data and syntheses. Anti-oxidant activity of the phenolics was determined by the inhibition of autoxidation of linoleic acid in a water-alcohol system. Anti-inflammatory activity of the isolated compounds was determined on mouse cars by using a tumour promoter, TPA (12-O-tetradecanoylphorbol-13-acetate) as an inducer.
