Abstract

The invention discloses a preparation method of vitex negundo leaf caffeine. According to the vitex negundo leaf caffeine, vitex negundo leaves are taken as a raw material, and the vitex negundo leaf caffeine is prepared through steps of preparation of the raw materials, color-protecting treatment, hot extraction, ultrasonic extraction, smashing, mixing, sublimation drying, arrangement, packaging and the like. According to the vitex negundo leaf caffeine prepared with the method, the widely existing vitex negundo leaves are taken as the raw material, so that the production cost is reduced; active materials of raw materials can be retained sufficiently through hot extraction and ultrasonic extraction treatment; loss of nutrient substances is reduced with a sublimation drying method; and further, the utilization rate of raw materials is increased, and the finished caffeine has health efficacy of exterior syndrome relieving, heat clearing, dampness removing, detoxification and the like.
