Abstract

The invention provides anextraction method of rhodiola. The extraction methodcomprises the following steps: weighing, crushing, removing impurities through water extraction, performing leaching extraction, concentrating an extract,performing alcohol precipitation and drying. The method of simultaneous extraction and separation is adopted, an extraction system and a separation and purification system are combined,specific and simple impurity removing method, extraction method and purification method are combined, the content of the obtained total flavones in the extract is higher than 90%, a selected preparation technology is simple and low in energy consumption and an environment-friendly production mode is achieved.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicines, and in particular relates to a method for extracting rhodiola medicinal materials. Background technique [0002] Rhodiola rosea, whose Latin scientific name is Rhodiola rosea, and whose English name is Roseroot, is a perennial herb or shrub of the Crassulaceae family, a rare wild plant that grows in the alpine and pollution-free areas at an altitude of 800-2500 meters. Due to its harsh growth environment, such as hypoxia, low temperature and dryness, strong wind, ultraviolet radiation, and large temperature difference between day and night, it has strong vitality and special adaptability. It is a traditional medicinal material commonly used in Asia. It has the functions of stimulating the nervous system, increasing work efficiency, eliminating fatigue and preventing altitude sickness. The common varieties of Rhodiola are small cluster Rhodiola, alpine Rhodiola, long whip Rhodiola, na...
