Effect on antioxidative activities of dried flower of Carthamus tinctorius processed by microbes fermentation / 中草药

ABSTRACT

Object Effects of Bacillus licheniformis (Weigmann) Chester C2-13 on antioxidative activities of dried flower of Carthamus tinctorius L. (DFCT) were studied. Methods Clearance of hydroxyl radical was determined by 1, 10-phenanthroline-Fe~(2+) oxidative assay. The hemolysis of red blood cells, MDA production in hematocytolysis liver homogenate were measured by colorimetric assay. Products of fermentation were analyzed by HPLC. Results C2-13 can increase greatly antioxidative activities of DFCT. Using HPLC assay, it is observed that the fermentation and processing by the strain can improve the effective components of DFCT. Conclusion Some effective components of DFCT may be biotransformed by C2-13, so that the antioxidative activities are promoted.
