Abstract
A rapid and efficient analysis and screening method is adopted for cell affinity capture coupled with HPLC-MS (CAC-HPLC-MS) analysis of bioactive components that have possible efficiency against cardiovascular diseases. This method involves affinity capture, concentration, and separation of bioactive components from Danshen library using oxidatively damaged endothelial cells induced by H2 O2 , as well as analysis and identification of targeted compounds with HPLC and MS. It combines the specific interaction between cell membrane receptors and bioactive components with the powerful analysis and identification function of HPLC-MS. The CAC-HPLC-MS method was also used for analysis and screening of bioactive components from crude extracts of Danshen. A total of 19 components were found to be bound to oxidatively damaged endothelial cells with seven of these identified. Existing literature confirms that these seven components have many activities related to cardioprotective diseases. Therefore, the combination of biological affinity capture with HPLC-MS should be regarded as an attractive method with great potential for rapid and efficient screening of bioactive components related to anti-cardiovascular diseases from natural product libraries.
