Problems solved by technology

But at present, the development and utilization of sweet potatoes is mainly to extract sweet potato starch, and in the production process of sweet potato starch, various components such as sweet potato protein, polysaccharides, vitamins are lost together with sweet potato starch mother liquor (commonly known as yellow pulp or starch wastewater), which not only pollutes environment, and a great waste of resources

Abstract

The invention belongs to the field of food or medicinal chemistry, and relates to a sweet potato saponin extract and an application thereof in the preparation of medicines or foods for preventing and / or treating tumors. The extract is extracted from a sweet potato starch mother liquor by a method in the invention. The sweet potato saponin extract can significantly inhibit the proliferation of tumor cells, and has a good tumor prevention and / or treatment prospect; and the method reuses starch wastewater resources, so the environmental pollution is reduced, and the method has important economicvalues and environmental protection meaning.

Description

technical field [0001] The invention belongs to the field of food or medicinal chemistry, and relates to a sweet potato saponin extract and its application in the preparation of drugs for preventing and / or treating tumors and health food. Background technique [0002] Tumor is a malignant disease that seriously threatens human health. In my country, cancer has become the number one cause of death, and the morbidity and mortality are still rising. In 2015, China is expected to have 4.292 million new cancer cases, which is equivalent to an average of new cases every day. 12,000 cases of cancer, and 2.814 million deaths, equivalent to an average of 7,500 people die of cancer every day. Finding and developing anti-tumor drugs with definite curative effect and less toxic and side effects has always been a hot spot and difficulty in drug innovation research and development. Due to the unique advantages of traditional Chinese medicine, extracting safe and effective parts from tradi...
