Abstract

In order to determine the scientificalness of traditionally processed Whitmania pigra, water extraction method and bionic extraction method were used respectively to extract the anticoagulating active components in W. pigra hanging dry products, talcum powder fried products and wine immersing-baked products. Activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), and antithrombin activity were selected as the activity indexes to evaluate the anticoagulant activities of different processed W. pigra. Then the contents of protein in different processed W. pigra were measured by Coomassie brilliant blue method to preliminarily explain the reason of anticoagulant activity changes. When water extraction method was used, the results of APTT, PT, TT and antithrombin activity showed that the anticoagulant activities of W. pigra were decreased both in talcum powder fried products and wine immersing-baked products, and the activity order was as follows: hanging dried products> wine immersing-baked products>talcum powder fried products. This order was same as the protein content order. While when bionic extraction was used, APTT was shortened in talcum powder fried products, but all the other results indicated the anticoagulant activities of W. pigra processed products were increased, and the activity order was as follows: wine immersing-baked products>talcum powder fried products>hanging dry products. As compared with water extraction, the bionic extraction was more similar to the absorption process of W. pigra in human digestive system after oral administration and was more scientific. Therefore, the traditional processing method can not only modify the taste and smell, but also enhance the anticoagulant activity of W. pigra.

Резюме

Compares water extraction vs simulated-gastric bionic extraction of Whitmania pigra — bionic extraction yields higher anticoagulant activity per gram of raw material.

Почему это важно для гирудотерапии

This study evaluated in vitro anticoagulant activities of different traditionally processed Whitmania pigra products (hanging dry, talcum powder fried, and wine immersing-baked) using both water extraction and bionic (simulated gastrointestinal) extraction methods, measuring APTT, PT, thrombin time, and antithrombin activity. Water extraction showed decreased anticoagulant activity in processed products (hanging dried > wine-baked > fried), while bionic extraction showed enhanced activity in processed products (wine-baked > fried > hanging dried), with the authors noting that bionic extraction better simulates oral absorption. This is relevant to hirudotherapy and traditional leech-based medicine as it provides evidence for optimizing preparation methods to maximize therapeutic potency. However, the study is limited to in vitro coagulation assays and protein content measurements; no pharmacokinetic, in vivo, or clinical data confirm that bionic extraction results translate to therapeutic outcomes.
