Abstract

The invention relates to a method for extracting lycopodine from lycopodium clavatum. The method comprises the following steps of: smashing the lycopodium clavatum to 80-100 meshes; adding 90-99% methanol the amount of which is 3-5 times that of the lycopodium clavatum, and carrying out reflux extraction for two-three times; recovering methanol from an extract solution; adding an acetic acid water solution in extract for dissolution; filtering, and then adding calcium oxide for drying; successively carrying out ultrasonic extraction with petroleum ether and chloroform; recovering chloroform from a chloroform extraction solution; adding silica gel for drying, and packing; and eluting a chloroform methanol mixed solution; carrying out a thin film test, collecting high-concentration flow fraction and recovering reagents; and carrying out dissolution and recrystallization for 2-3 times with absolute ethyl alcohol, and drying a crystal substance so as to obtain the pure lycopodine product. According to the invention, the method is adopted to produce the lycopodine, so as to reduce environmental pollution; and the method has the advantages of good stability and high specificity.

Description

Technical field: [0001] The invention belongs to the field of natural medicine and chemistry, and in particular relates to a method for extracting lycoperme from Herba chinensis. Background technique: [0002] Lycoperine is a quinolizidine alkaloid with molecular formula C 16 h 25 NO, molecular weight 247.38, columnar crystal, melting point 116°C. Optical rotation -24.5 (c=1.1, ethanol). Soluble in benzene and chloroform, etc. [0003] Lycoperpine is an alkaloid extracted from Lycopodium, which has antihypertensive, antipyretic, antibacterial and excitatory effects. [0004] Streptococcus japonicum is the rhizome and root of the dry rooted whole plant of Lycopodium japonicum Thunb. in Lycopodium japonicum Thunb. It dispels wind and cold, dehumidifies and reduces swelling, and has the functions of relaxing tendons and activating collaterals. [0005] Existing methods for extracting lycoperme from Streptococcus sinensis are few, because the alkaloids in Streptococcus sin...
