  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.

  candidates for preventing and treating conditions in which oxidative stress is a contributing factor. In this study, we report the design, synthesis and antioxidant activity of six compounds containing the 2-methoxyphenol moiety core structure. The synthesized derivatives were characterized using 1H NMR, 13C NMR, Fourier-transform infrared (FT-IR), and elemental analysis spectroscopy. The antioxidant properties
