Embodiment 1

[0030] 20g of the dry powder of the young leaves of the green thorn, immersed in 200mL of ethanol solution with a volume concentration of 50% at room temperature, that is, the mass volume ratio (solid-liquid ratio) of the dry powder of the green thorn to the ethanol solution is 1:10, ultrasonic extraction 2 times, Each time for 30 minutes (500W), the filtrates were combined and rotary evaporated to dryness under reduced pressure to obtain 2.05 g of the crude extract of the young leaves of the green thorn, with a yield of 10.25%.

Embodiment 2

[0032] 20g of dried green thorn powder, submerged in 200mL of 60% ethanol solution at room temperature, that is, the mass volume ratio (solid-liquid ratio) of green thorn dry powder to ethanol solution is 1:10, ultrasonic extraction 2 times, each time After 30 minutes (500W), the filtrates were combined and rotary evaporated to dryness under reduced pressure to obtain 2.12 g of the crude extract of the green thorny young leaves, with a yield of 10.60%.

Embodiment 3

[0034] 20g of dried green thorn powder, immersed in 200mL of 70% ethanol solution at room temperature, that is, the mass volume ratio (solid-to-liquid ratio) of green thorn dry powder to ethanol solution is 1:10, ultrasonic extraction 2 times, each time After 30 minutes (500W), the filtrates were combined and rotary evaporated to dryness under reduced pressure to obtain 2.24 g of the crude extract of the young leaves of the green thorn, and the yield was 11.20%.

Abstract

The invention discloses a tender leaf extract of prinsepia utilis as well as a preparation method and applications of the tender leaf extract. The preparation method can be any one of the two following methods: method I: soaking smashed tender leaves of prinsepia utilis in ethanol solution, carrying out extraction for 0.2-1.5 h, carrying out solid-liquid separation to obtain a filtrate, and carrying out reduced pressure rotary evaporation on the filtrate till the drying state, thus obtaining a crude tender leaf extract of prinsepia utilis; method II: (1) preparing the tender leaf crude extract of prinsepia utilis through the method I; (2) dissolving the crude extract in deionized water, loading the crude extract to a macroporous resin packed column, carrying out elution by adopting a solvent I, a solvent II and a solvent III in sequence, collecting the eluents, and removing the solvents from the eluents, thus obtaining an elution part A, an elution part B and an elution part C. The preparation method is simple and convenient, and is easy to operate, high in yield, and suitable for popularization and application; the extract contains various ingredients, the ingredients achieve a synergistic effect, and thus the good efficacies of resisting senility, resisting oxidation and resisting ageing are achieved.

Description

technical field [0001] The present invention relates to an extract of young leaves of green thorns and its preparation method and application. Background technique [0002] Green thorn point (Prinsepia utilis), scientific name Prinsepia utilis, plant of the genus Prinsepia in the Rosaceae, aliased as cannon tube fruit, milk hammer, chicken cake, plum blossom thorn, spear fruit, Anas, Mengzi Prinsepia utilis. Green thorn point seeds are rich in oil, the general oil yield is about 30%, the oil is dark brown, clear and transparent, and white as lard after solidification; the oil can be used for edible, soap making, and lighting. The tender tips can be eaten as vegetables. Green thorns grow on hillsides, streams or bushes at an altitude of 1000-2650m, and are mainly distributed in Yunnan, Guizhou, Sichuan, Taiwan, Tibet and other provinces. The green thorn tip was first recorded in "Southern Yunnan Materia Medica", which said: "The nature is cold, and the taste is bitter. Atta...
