ABSTRACT: Objective To investigate the effects of different drying methods on the quality of Lonicera macranthoides. METHODS Lonicera macranthoides was processed by shade drying, sun drying, drying, microwave drying equipment, vacuum drying and far infrared drying, and its appearance was observed. The content of chlorogenic acid in Lonicera macranthoides was determined by HPLC. Results The appearance of vacuum dried samples was good, and the content of chlorogenic acid was high, which was obviously better than that of other drying methods. CONCLUSION The method is sensitive, accurate and reproducible. It can be used for the processing and quality control of Lonicera macranthoides from Sichuan province.
Key words: Lonicera macranthoides microwave drying; drying method; microwave drying; vacuum drying; far infrared drying; medication quality; chlorogenic acid; high performance liquid chromatography
Lonicera macranthoides is a dry bud or first-blooming flower of Lonicera macranthoides, which has the functions of anti-bacterial, anti-inflammatory, cooling and dispersing wind-heat, clearing away heat and detoxifying toxins. It is mainly used to treat such diseases as carbuncle, larynx arthralgia, heat-poisoning hemorrhoea, wind-heat cold and warm-fever. It is known as penicillin in traditional Chinese medicine.
