Effects of Chrysanthemum coronarium Extract on Fermentation Characteristics and Biohydrogenation of Polyunsaturated Fatty Acids in vitro Batch Culture

摘要

IntroductionCis-9,trans-11 CLA has been shown to be potentially healthpromoting CLA in many animal models.The C18∶1 trans-11 fatty acid (VA) is also desirable as a product flowing from the rumen,because the flow from the rumen of VA play a more important role than CLA in determining CLA concentration in animal tissues.The factors which affect CLA content in milk have been studied mainly in dairy cows and most factors are basically dietary factors,especially fat source(e.g.,plant oils,fish oil,et al.).Recently some researches showed that some plants or plant extracts could increase cis-9,trans-11 -CLA content in milk.The purpose of this experiment was to evaluate the effects of Chrysanthemum coronarium extract on in vitro Biohydrogenation of polyunsaturated fatty acids and fermentation characteristics of mixed rumen microorganisms.
