Embodiment Construction

[0037] The technical solution of the present invention will now be further described in conjunction with the embodiments and the accompanying drawings.

[0038] Fresh water hemp leaves: Picked from Yangshan District, Shaanxi Province, the species of water hemp was identified by Tian Xianhua, a professor of plant taxonomy at the School of Life Sciences, Shaanxi Normal University.

[0039] Wild water hemp leaf extract of the present invention is made by following method:

[0040] (1) Water hemp leaf pretreatment

[0041] The fresh wild water hemp leaves are dried in the shade at room temperature (25-28 DEG C), pulverized with a pulverizer, and passed through a 80-120 mesh sieve to obtain the water hemp leaf powder.

[0042] (2) Ultrasonic extraction

[0043] Put the water hemp leaf powder into a container, add an extraction solvent, heat up to 30-70°C, use an ultrasonic generator to ultrasonicate for a certain period of time, and collect the extract.

[0044] (3) Extract conc...

Abstract

The present invention relates to wild debregeasia orientalis leaf extract. The extract is prepared by taking wild debregeasia orientalis leaves as a raw material, and conducting drying, pulverizing, ultrasonic-assisted solvent extraction, filtration, centrifuging, pressure-reduced distillation, macroporous resin absorption and desorption, pressure-reduced distillation and vacuum freeze drying. Thewild debregeasia orientalis leaf extract is high in the content of specific polyphenols, is rich in phenolic acid substances such as chlorogenic acid and caffeic acid, especially high in chlorogenicacid content, is a natural active product with high bioactivity, can be used as an effective component for preparing a health food with an anti-oxidation function and for preparing a health food capable of preventing cancer cell proliferation, can be applied to the fields of foods and biological drugs, and has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of food and biomedicine, and in particular relates to a natural wild water hemp leaf extract and its new application in anti-oxidation and prevention of cancer cell proliferation and the like.
