Problems solved by technology

However, its preparation method is relatively complicated, and multi-carbon alkane alcohols are introduced in the preparation process, which can easily cause further damage to the health of patients.
[0010] At present, there is no method for extracting high-purity stachyose in my country that has an ideal promotion effect on the treatment of esophageal cancer, and there is no such a composition for the treatment of esophageal cancer. The components are simple and effective, and the preparation method is simple, easy to operate, and non-toxic harmless composition

Abstract

The invention relates to a stachyose extraction method and applications thereof. High purity stachyose is obtained by following steps: preprocessing, extracting, reflux extracting, filtering, discoloring, ion exchanging, and concentrating. The invention also discloses applications of stachyose. The experiment results show that the purity of stachyose obtained by the provided extraction method is high, and the application effect is good.

Description

technical field [0001] The invention relates to the technical field of stachyose extraction. Specifically, the present invention relates to a method for extracting stachyose. The present invention also relates to the application of the stachyose. Background technique [0002] Esophageal cancer is one of the common malignant tumors, the incidence rate ranks fifth among all kinds of malignant tumors, and the mortality rate ranks fourth. my country is a country with a high incidence of esophageal cancer. There are about 250,000 newly diagnosed cases of esophageal cancer every year, accounting for 50% of the world's esophageal cancer cases. About 150,000 people die from esophageal cancer every year, accounting for 100% of all malignant tumor deaths. 25 / 25, (this data is extracted from "Chinese Journal of Traditional Chinese Medicine" 2018, No. 8, page 969 and "Guidelines for the Diagnosis and Treatment of Malignant Tumors of Traditional Chinese Medicine" edited by Lin Hongsheng...
