Abstract

The invention discloses a decoction-free extraction process for precious Chinese herbal medicines. The process includes the steps: 1) cleaning, drying and grinding the Chinese herbal medicines into 20-30-mesh particles; 2) adopting a supercritical CO2 extraction process for removing heavy metals from the Chinese herbal medicine particles obtained at the step 1); 3) roasting the Chinese herbal medicine particles with the heavy metals removed at the step 2) for 50-60min at the temperature of 45-50 DEG C until the water content is 0.3-0.5wt%; 4) subjecting the Chinese herbal medicine particles roasted at the step 3) to ultrafine pulverization until the particle size is 0.35-0.75micrometer; 5) performing wall-breaking treatment, namely adding auxiliary materials into the Chinese herbal medicine particles obtained at the step 4), and extracting active ingredients by application of a low-temperature micro-nano wall-breaking technique. By effective rejection of heavy metal pollution, pharmacological functions of the Chinese herbal medicines can be improved, and side effects are reduced; by application of the cell wall breaking technique for powder processing, biological activity and bioavailability of the Chinese herbal medicines can be improved.

Description

technical field [0001] The invention relates to the technical field of biopharmaceutical / health product production, and mainly relates to a decoction-free extraction process of precious plant Chinese medicinal materials. Background technique [0002] Chinese herbal medicines are special products that people use to prevent and treat diseases, and they should first of all be non-toxic to the human body. Once Chinese herbal medicines are polluted by pesticides and heavy metals, they may pose a potential threat to the human body, especially the sick. [0003] Usually the detoxification function is poor, and the harm caused is greater than that of ordinary people. This will not only fail to cure the disease, but aggravate and delay the treatment of the patient. [0004] In recent years, the annual sales of the world's herbal medicine market has reached 40 billion US dollars, and it is increasing at a rate of 10% per year. At present, it only accounts for about 1% of the world's...
