Abstract

The invention discloses an extraction and separation method for lycorine in Lycoris radiata. Lycoris radiata bulbs are taken as a raw material, and the lycorine is extracted by adopting complex enzyme pretreatment, dilute hydrochloric acid leaching, ultrasonic-assisted extraction, and chloroform extraction methods. An adopted novel process effectively combines an ultrasonic extraction method with a composite enzymatic hydrolysis method, which shortens extraction time, and also greatly improves the extraction rate of the lycorine; and the extraction rate reaches 0.97 percent, and is higher than that of the prior extraction process. The method has the advantages of mild reaction conditions, simple needed equipment, concise flow, and reasonable and feasible process.

Description

【Technical field】 [0001] The invention relates to a method for extracting traditional Chinese medicine. In particular the present invention relates to a method for extracting lycorine from Lycoris. 【Background technique】 [0002] Lycoris is a monocot class Amaryllidaceae (Amaayllidaceae) plant, which is a perennial herb. According to incomplete statistics, there are about 20 kinds of them all over the world, all of which are beautiful flowers, mainly distributed in China and Japan. There are many biologically active components in Lycoris, especially alkaloids. After research, the bulbs of Lycoris plants contain more than ten kinds of alkaloids, such as lycorine, lycorine, lycorine, and pseudolycorine. With the continuous research on the medicinal use of Lycoris alkaloids in recent years, many new therapeutic effects have been discovered. These alkaloids not only have anti-inflammatory, antibacterial and anti-cancer effects, but also inhibit cholinesterase and stimulate n...
