Problems solved by technology

Highland barley is the most important food crop on the Qinghai-Tibet Plateau. However, due to backward processing technology and poor taste of the product, although it has played an important role in solving the food and clothing problems of local farmers and herdsmen, the development of deep processing and comprehensive utilization of highland barley agricultural products will improve its quality. Added value, more imminent
Highland barley bran is the main processing by-product of highland barley flour factory. It also contains many valuable substances, such as β-glucan, highland barley germ and highland barley bran oil. However, the comprehensive utilization rate of highland barley bran is very low at present, and most of them are used as feed

Abstract

The invention relates to application of barley bran oil to preparing a drug for reducing TC, TG and LDL-C contents and rising HDL-C level content in serum of a patient. The barley bran oil can be used as a raw material of a blood cholesterol modifying agent, an arteriosclerosis therapeutic agent and a preventive agent in the medicine industry.

Description

technical field [0001] The invention belongs to the technical field of grain and oil deep processing, and in particular relates to the use of highland barley bran oil extracted from highland barley bran to reduce TC, TG and LDL-C contents in mouse serum and increase HDL-C content. Background technique [0002] Highland barley belongs to one of the barley varieties of the genus Hordeum in the family of Gramineae in terms of plant classification. Highland barley is the most important food crop on the Qinghai-Tibet Plateau. However, due to backward processing technology and poor taste of the product, although it has played an important role in solving the food and clothing problems of local farmers and herdsmen, the development of deep processing and comprehensive utilization of highland barley agricultural products will improve its quality. Added value is more imminent. Highland barley bran is the main processing by-product of highland barley flour factory. It also contains m...
