Screening of anticoagulant active components in Xuefu Zhuyu decoction via affinity-ultrafiltration coupled with mass spectrometry.

Abstract

This study aimed to establish an effective affinity-ultrafiltration coupled with mass spectrometry (AUF-MS) method to rapidly screen the active components of antithrombin in Xuefu Zhuyu decoction (XFZYD). The HPLC fingerprint of different batches of XFZYD was established to verify the stability of the compound ingredients. AUF-MS was established for the rapid screening of the active ingredients in XFZYD. Eight active ingredients were screened using AUF-MS: oxypaeoniflorin, chlorogenic acid, amygdalin, isoliquiritin, neohesperidin, hesperidin, glycyrrhizic acid and chikusetsu saponin IVa. Simultaneously, the anticoagulant effect of the active ingredients was verified by performing in vivo and in vitro experiments. The results of this study indicate that AUF-MS can be used for high-throughput screening of active components of traditional Chinese medicine compounds, thus providing a basis for the discovery of thrombin inhibitors and promoting the research progress of antithrombotic drugs. The compounds screened from XFZYD showed an inhibitory effect against thrombin and a certain antithrombotic effect.
