Problems solved by technology

And conventional extraction method, the content of the effective substance that obtains extracting is little, often exist after time-consuming and laborious extraction, but the amount of the effective substance that extracts is too little, causes the waste of energy, the waste of raw material, and has seriously affected follow-up medicine Preparation, so that there are many unnecessary steps in the subsequent drug preparation process
[0009] However, there is currently a lack of a method that can effectively extract the alkaloids in Physiophthora, and the alkaloids in Physiophthora cannot be effectively utilized.

Abstract

The invention provides a method for extracting alkaloid extract from stems and leaves of physochlaina, and relates to the technical field of extraction of plant effective components. The method for extracting the alkaloid extract from the stems and leaves of the physochlaina comprises the following steps: drying and crushing the stems and leaves of the physochlaina to obtain physochlaina powder; performing water extraction on the physochlaina extract powder, and collecting filtrate after water extraction; freeze-drying the water-extracted filtrate to obtain a dried product; and washing the dried product with ethanol, and drying to obtain the alkaloid extract. According to the method, the fresh physochlaina stems and leaves are extracted, the content of extracted alkaloid is high, the loss of effective components is less, and the quality of the prepared extract can be improved. The extract prepared by the method disclosed by the invention is high in content of effective substances, and the preparation method is simple and convenient, and can be put into large-scale production. After the physochlaina is dried and crushed, the physochlaina is subjected to water extraction in three times, so that the alkaloid in the stems and leaves of the physochlaina can be hydrolyzed into water, and the content of the alkaloid in the extract is further increased.

Description

technical field [0001] The invention relates to the technical field of extraction of effective plant components, in particular to a method for extracting alkaloid extract from stems and leaves of Herba Phyllosa. Background technique [0002] Vesicle grass is a Chinese medicine name. Physiophthora is the whole herb of Solanaceae plant Physiophthora. In early summer, when the plants grow vigorously, the whole grass is collected and dried in the shade. Born in hillsides, ravines and grasslands. Physiophthora is distributed in Heilongjiang, Inner Mongolia, Hebei and Xinjiang in my country. Its taste is bitter, cool in nature. poisonous. The root invigorates the kidney and warms the middle, soothes the nerves and calms asthma. Cure mainly deficiency-cold diarrhea, overstrain, cough, phlegm and dyspnea, palpitation and uneasiness. The whole plant clears heat and detoxifies, dispels dampness and kills parasites. Indications for otitis media, sinusitis, sore throat, poisonin...
