Abstract

The invention relates to research of an extract of total flavone of eucommia bark, and in particular to an extraction method of total flavone of eucommia bark and an application of the total flavone of eucommia bark in antioxidants and hypoglycemic agents. According to the invention, eucommia bark is taken as a raw material to extract total flavone in the eucommia bark by a microwave-assisted method, wherein an optimal extraction condition of the total flavone is determined by setting a single-factor experiment and optimizing a response surface. The invention provides the application of the total flavone in oxidation resistance and hypoglycemic activity.

Description

technical field [0001] The invention belongs to the research related to the extract of eucommia ulmoides, in particular to a method for extracting total flavonoids of eucommia ulmoides and its application in antioxidants and hypoglycemic agents. Background technique [0002] The fruit of Eucommia ulmoides is developed from two oblong carpels, and its essence is a nut. Because it is surrounded by thin leathery wings, it is also called samara customarily. Eucommia samara is flat, oblong. There are wings around, the wings are leathery, and the top is slightly concave. The fruit growth period is from April to October. There is a joint at the junction of the ovary peduncle and the fruiting stem. Seeds are flat, linear, 1.4-2.5cm long, 5mm wide, about 2mm thick, rounded at both ends, slightly concave at both ends. [0003] Eucommia ulmoides is a precious and ancient Chinese medicinal material. Scholars from various countries have conducted a lot of research on the chemical comp...
