Problems solved by technology

[0004] At present, there is no research on the extraction of total flavonoids from the branches and leaves of Nitraria japonica in the existing technology. The simple extraction method using ethanol is not efficient, resulting in low yield of flavonoids, incomplete recovery of organic solvents, high extraction costs, etc.

Embodiment 1

[0040] 1. Cleaning: select 10kg of mature Nitraria branches and leaves, sieve out the sediment, and wash with water;

[0041] 2. Drying: Dry the cleaned Nitraria branches and leaves at 15°C for 15 hours at low temperature;

[0042] 3, crushing: the Nitraria branches and leaves obtained in step 2 are ultrafinely pulverized to obtain Nitraria branches and leaves powder;

[0043] 4. Extraction: Add 5 times the amount of 70% ethanol to the Nitraria branch and leaf powder obtained in step 3 for ultrasonic extraction for 1 hour, stir with a stirrer during this period, obtain filtrate I and filter residue I after filtration, and use filter residue I again for 7 times A large amount of 70% ethanol was refluxed and extracted for 1 h, and the filtrate II and filter residue II were obtained after filtration, the filtrate I and the filtrate II were combined, and concentrated under reduced pressure to obtain the crude extraction part of the total flavonoids of the branches and leaves of Ni...

Embodiment 2

Abstract

The invention relates to a nitraria branch and leaf extract. Nitraria branches and leaves obtained through cleaning, drying, crushing, bur picking, extraction, purification and the like have the health-care functions of delaying aging and reducing blood glucose and blood fat. A preparation method of the nitraria branch and leaf general flavone extract is simple in process, easy to operate, relatively high in yield and favorable in quality and facilitates industrial production and processing.

Description

technical field [0001] The invention relates to the field of plant extracts, in particular to an extract of the branches and leaves of Nitraria japonica with the functions of delaying aging, lowering blood sugar and lowering blood lipid and a preparation method thereof. Background technique [0002] Nitraria is a plant belonging to the genus Nitraria of Tribulus terrestae. It is a small deciduous shrub. Nitraria plants adapt to the environment in various forms by virtue of various forms of xeric physiological functions and xeric structures. They reproduce tenaciously, survive and form vegetation communities. , preventing quicksand from invading the oasis and maintaining the stability of the oasis environment has a great effect. Therefore, Nitraria is an ideal afforestation tree species for controlling deserts and saline-alkali lands in the northwest, greening the environment, improving soil, improving the ecological environment, and improving the living standards of local res...
