Abstract

The present invention relates to the research on 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. The optimal extraction conditions of flavonoids were determined by setting up single factor experiments and response surface optimization, and the application of antioxidant activity and hypoglycemic activity of total flavonoids was provided.

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...
