Molecular distillation technology in plant extracts
The ingredients of traditional Chinese medicine are complex, and while retaining the active ingredients, it is necessary to remove impurities such as protein, precipitation, resin, and tannin as much as possible. At the same time, quite a fewPlant extractsThe active ingredients in Chinese medicine are sensitive to heat and easy to oxidize and decompose. In the traditional separation and purification process, on the one hand, it is not easy to remove impurities, and it is easy to lose active ingredients; on the other hand, high temperature or residual organic chemicals make it lose its naturalness and destroy its physiological and pharmacological activities. Therefore, the use of new separation technology to separate and purify active ingredients in traditional Chinese medicine has become a focus of Zhongguan Jianye R & D Center. Molecular distillation technology is a new type of separation technology developed in recent years. It is widely used due to its unique advantages in the separation of high boiling point and heat-sensitive substances. The mature technology of molecular distillation technology in the extraction and separation of the active ingredients of traditional Chinese medicine, such as: the extraction and purification of Melaleuca alternifolia essential oil (tea tree oil), the separation and purification of rose essential oil, the purification of Tripterygium chinensis oil, the enrichment of the active ingredients of fragrant oil, the separation and purification of volatile oil of Artemisia sp. calyx flower fatty acids and so on.
As a new type of high-tech separation technology, molecular distillation technology fills the shortcomings of conventional vacuum distillation. It is mainly suitable for the separation and purification of high boiling point and heat-sensitive materials, and has unique advantages in the separation and purification of active ingredients and monomers of traditional Chinese medicine. Our country is rich in traditional Chinese medicine resources, and with the development of people's pursuit of natural trends in recent years and the progress of the modernization of traditional Chinese medicine in our country, molecular distillation technology has been more and more widely used, especially molecular distillation technology combined with traditional extraction and separation technology and supercritical extraction technology is applied to the traditional Chinese medicine industry, and the prospect is attractive.
