Abstract

The invention relates to a method for promoting extraction of active components in honeysuckle flower by microwaves. The active components in the honeysuckle flower can be extracted with a solvent and subjected to further processing. The extraction of the honeysuckle flower generally uses water or ethanol as the solvent, and a microwave action is further used, thereby enhancing the yields of the main components and shortening the extraction time.

Description

technical field [0001] The active ingredients in honeysuckle can be extracted with a solvent before further processing. The extraction of honeysuckle generally adopts water or ethanol as a solvent, and the present invention further uses microwaves to improve the yield of each main component and shorten the extraction time. Background technique [0002] Honeysuckle, also known as double flower, two flower, soil silver flower, silver flower, honeysuckle flower, handkerchief flower, etc., is the flower bud of Lonicera Lonicera. It is a semi-evergreen winding vine for many years in my country, growing in the mountains or artificially cultivated. Honeysuckle is one of the 38 kinds of precious Chinese medicinal materials managed by the state. Its stems, leaves and flowers can be used as medicine. In terms of growth characteristics, honeysuckle can be divided into woody and vine. Woody honeysuckle can grow continuously for 15 to 20 years, with concentrated flowering, long flower b...
