揮發油是中药主要成分之一,不論从事于中药化学研究或剂型改進,对其提取方法來說都是非常重要的,作者茲就过去在药厂工作时生產揮發油的片段經驗,纂輯报導,提供学者参考。提取揮發油的方法甚多,水蒸气蒸溜法为其中常用方法之一,其优点在于設备單純,操作簡便,时間經济,同时在一定的条件下,还可以得到接近理論数量的產量。 Volatile oil is one of the main components of traditional Chinese medicine. Regardless of whether it is engaged in the study of Chinese medicine chemistry or the improvement of dosage form, it is very important for its extraction method. The authors hereby report on the experience of producing volatile oil in the past when working in a pharmaceutical factory. Provide scholar reference. There are many methods for extracting volatile oil. Steam distillation is one of the commonly used methods. Its advantages are simple equipment, easy operation, and economic time. At the same time, under certain conditions, it can also obtain a yield close to theoretical quantity.
