吐温80为聚氧乙烯去水山梨醇油酸醋,属非离子型表面活性物质,在制剂中常用作助溶剂、澄清剂,特别在中草药成份的制剂中占有重要地位。我们在研究中草药有效成份的药理作用过程中,发现作为助溶剂的吐温80亦有明显的药理作用,故特地作了一些观察,现将结果整理如下,供药理、制剂等工作者参考。 Tween 80 is a polyoxyethylene sorbitan oleic acid vinegar, which is a non-ionic surface active substance. It is often used as a cosolvent and clarifier in preparations, and plays an important role in the preparation of Chinese herbal medicines. During the study of the pharmacological action of the active ingredients of Chinese herbal medicine, we found that Tween 80 as a cosolvent also has obvious pharmacological effects. Therefore, we made some observations. The results are now collated as follows for reference by pharmacological agents, preparations, and other workers.
