Analysis of the anthocyanin profiles and anti- TGEV activity from purple cabbage

To explore the inhibitory action of anthocyanins from purple cabbage( APC) for transmissible gastroenteritis virus of swine( TGEV) in vitro. APC powder as raw material,the sample of anthocyanins structure were identified by HPLC- MS method,APC were acted on disseminated TGEV in monolayer ST cells,then its influence on the morphological changes as well as cell survival were researched,it was evaluated whether APC had the active role of anti- TGEV. The results showed that the purple cabbage contained at least 13 kinds of anthocyanins,the main component was cyaniding- glucosides.The maximum safe mass concentration of APC was100μg / m L for ST cells nontoxicity.Introduced TGEV to ST,APC could restrain ST cell morphological changes and less death rate under the 100μg / m L. In summary,anthocyanins from purple cabbage had significantly anti- TGEV biological activity.
