Mesembryanthemum crystallinum D-pinitol extract with hypoglycemic effect as well as preparation method and application thereof

Abstract

The invention relates to the technical field of plant extraction, in particular to a mesembryanthemum crystallinum D-terpineol extract with hypoglycemic effect as well as a preparation method and application thereof. The method comprises the following specific steps: material pretreatment, vacuum freezing combined with vacuum microwave drying, material crushing, and extraction of mesembryanthemumcrystallinum D-pinitol by response surface method. According to the method, mesembryanthemum crystallinum is dried through a vacuum freezing and vacuum microwave drying combined technology, then the mesembryanthemum crystallinum D-pinitol is extracted through response surface method, meanwhile, water is taken as an extraction solvent, operation is easy, the price is low, the extraction rate is high, and active ingredients in mesembryanthemum crystallinum can be reserved to the maximum extent. The mesembryanthemum crystallinum D-terpineol extract prepared by the method can significantly reducepostprandial blood glucose and fasting blood glucose of diabetic rats, improve glucose tolerance and repair damaged pancreatic beta cells, and has the effect of improving diabetic syndrome.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to an extract of ice vegetable D-pinitol with hypoglycemic effect, its preparation method and application. Background technique [0002] Ice vegetable (Mesembryanthemum crystallinum Linn.), also known as ice leaf sunflower, ice grass, belongs to Apricotaceae, distributed in Africa, Europe, western Asia and other places, and is used as a new green and healthy vegetable in Japan, South Korea, the United Kingdom and other countries. Vegetables are eaten and gradually introduced into our country in recent years. A large number of vesicular cells containing salt are attached to the bottom of the leaf surface and the stem of the ice vegetable. It has a slightly salty taste, a crisp taste, and a unique flavor. It can be eaten raw or fried, and has high nutritional value. Iced vegetables are rich in vitamins (vitamin A, vitamin K, pantothenic acid), minerals (sodium, potassium, ca...

AI Technical Summary

Problems solved by technology

D-pinitol can be prepared by chemical synthesis, but there are many reaction steps, and the reaction conditions are difficult to control, which makes the chemical synthesis cost expensive. Relatively speaking, the cost of extracting D-pinitol from plants is lower

Iced vegetable is an important plant resource for extracting D-pinitol, but the current research on iced vegetable mainly focuses on its biology and cultivation. There is no report on extracting D-pinitol from iced vegetable, and The research on the efficacy of vegetable D-pinitol extract in lowering blood sugar has not yet been reported.
