Abstract

The invention belongs to the technical field of medical food, and discloses an extraction and purification method of amygdalin in Cerasus humilis kernel. The adopted purification method is simple and effective and can extract the amygdalin in Cerasus humilis kernel to the largest extent. The obtained amygdalin not only can be used for relieving cough and resisting inflammatory, but also can be used for treating tumor, thus the method of the invention has wide application prospect in the pharmaceutical field.

Description

Technical field: [0001] The invention relates to a purification method, in particular to a method for extracting and purifying amygdalin from Prunus japonicus, and belongs to the technical field of medicine and food. Background technique: [0002] Ou Li is a species of Rosaceae cherry shrub species endemic to China. It is wild and mainly distributed in Shanxi, Hebei, Shaanxi, Inner Mongolia and Northeast China in the central and western regions. Ou Li has a very high economic value and has a wide range of uses. The pulp is edible, the kernel can be used as medicine, and the stem can be used as feed and weaving material. Its development and utilization prospects are very broad. [0003] Amygdalin has good medicinal value and is widely found in the seeds of various Rosaceae fruits such as apricots, peaches, plums, apples, hawthorns, and loquats. The molecular structure of amygdalin is composed of one unit of benzaldehyde, one unit of hydrocyanic acid and two units of glucose...
