Abstract

The invention relates to the technical field of extraction of selenium polysaccharide, and relates to a selenium polysaccharide in penny cress, an extracting method of the selenium polysaccharide in the selenium-rich penny cress, and application of the selenium polysaccharide in the penny cress. The provided extracting method of the selenium polysaccharide in the selenium-rich penny cress comprises the following steps: preprocessing the raw material, extracting, centrifuging, concentrating, removing impurities, precipitating with alcohol and drying, wherein the extracting temperature is 40-65 DEG C, the extracting time is 1-3 and the extracting time is 15-30 minutes each time in the extracting step, and the extracting is conducted with ultrasonic assistance and / or enzyme treatment. The effective active ingredients in the raw material are effectively extracted, the operation is simple and feasible, the extracting efficiency is high, the cost is low, and the method has a remarkable comprehensive economic benefit.

Description

technical field [0001] The invention relates to the technical field of extracting selenium polysaccharides, in particular to a method for extracting selenium polysaccharides from selenium cabbage and selenium-enriched cabbage and an application thereof. Background technique [0002] Beetroot is an annual or perennial herbaceous plant belonging to the family Brassicaceae, native to central, western and southern Europe. It is mainly distributed in the Enshi Autonomous Prefecture of Hubei Province in my country. It is a kind of geographical plant resource in this area. It is mainly distributed in the "selenium" deposit within the radius of 150 kilometers of Enshi Shuanghe Bridge (Xuanen, Hefeng, Jianshi) Above, the locals also call it wild rape or saxifrage. The round-leaf cabbage has a strong selenium adsorption capacity, and the selenium-rich round-leaf cabbage has become a delicacy on the table of the local people to entertain merchants from "selenium-deficient" regions. Af...
