Abstract

The invention discloses a production method for folium viticis negundo caffeine. The folium viticis negundo caffeine is produced by the following steps: adopting folium viticis negundo as a raw material, preparing the raw material, carrying out color protection treatment, carrying out heat extraction, carrying out ultrasonic extraction, crushing, mixing, lyophilizing and drying, classifying and packaging and the like. The folium viticis negundo caffeine produced by the method takes the widely-existing folium viticis negundo as the raw material and the production cost is reduced; the heat extraction treatment and the ultrasonic extraction treatment are carried out so that active matters of the raw material can be sufficiently kept; a lyophilizing and drying method is adopted so that the loss of nutrient substances is reduced and the utilization rate of the raw material is reduced; the finished-product caffeine has the health-care effects of relieving exterior syndrome and clearing heat, draining dampness and detoxifying and the like.
