Abstract

The invention provides a method for rapidly culturing and producing galanthamine, lycorine and lycoramine by rapid propagation of bulblets of lycoris. The method comprises the following steps: taking a bulb of 'lycoris chinensis' as an explant, sterilizing, inoculating and culturing for a period of time, generating bulblets at a wound of a scale, and continuing carrying out multiplication culture on the bulblets; and drying tissues of the bulblets of the lycoris chinensis, grinding and ultrasonically extracting with methanol for three times to obtain a methanol solution containing the galanthamine, the lycorine and the lycoramine. The problems that resources of lycoris herbs are in shortage, and chemical synthesis of the galanthamine, the lycorine and the lycoramine is complicated are solved by a tissue culturing technology. According to a used basic medium, an SH medium is used as a base, and ingredients such as 6-benzylamino adenine, alpha-naphthylacetic acid and a yeast extract are used as auxiliary ingredients; and the method lays a foundation for industrial production of the galanthamine, the lycorine and the lycoramine and is environment-friendly, raw materials are abundant, and the supply gap of markets to the galanthamine, the lycorine and the lycoramine can be relieved well.

Description

technical field [0001] The invention relates to the production of galantamine, lycorine and lycorine, in particular to a method for producing galantamine, lycorine and lycorine from Chinese lycoris bulbs. Background technique [0002] Galanthamine, also known as Galanthamine, has a chemical formula of C 17 h 21 NO 3， The molecular weight is 287.36. White or light yellow crystalline powder. Odorless, bitter taste. The melting point is 127-129°C. Soluble in ethanol, acetone, chloroform, insoluble in benzene, ether, water. Usually, the bulbs of Amaryllidaceae (Amaryllidaceae) are used as raw materials, and they are repeatedly extracted and refined with ethanol and chloroform under different acidities. Galantamine hydrobromide is used for myasthenia gravis, progressive muscular dystrophy, sequelae of poliomyelitis, children with cerebral palsy, sensory or movement disorders caused by nervous system diseases, and multiple neuritis. The oral dosage form of this drug can be...
