Embodiment 1

[0041] A kind of preparation method of the bamboo leaf extract of present embodiment comprises the steps:

[0042] (1) Clean the green bamboo leaves, dry them at 60°C to constant weight, and then pulverize them, and pass through a 120-mesh sieve;

[0043] (2) Ultrasonic extraction was added for 3 times with absolute ethanol, the ultrasonic frequency was 30-50kv, the ratio of solid to liquid was 1:20, 1:10, 1:8, the extraction temperature was 68°C, and the extraction time was 20min. After filtering, combining the filtrates, concentrating and vacuum-drying, the extract of bamboo leaves is obtained.

Embodiment 2

[0045] A kind of preparation method of the bamboo leaf extract of present embodiment comprises the steps:

[0046] (1) Clean the green bamboo leaves, dry them at 55°C to constant weight, and then pulverize them, and pass through a 100-mesh sieve;

[0047](2) Add absolute ethanol and ultrasonically extract 3 times, the ultrasonic frequency is 30-50kv, the ratio of solid to liquid is 1:15, 1:10, 1:10, the extraction temperature is 70°C, and the extraction time is 10min. After filtering, combining the filtrates, concentrating and vacuum-drying, the extract of the bamboo leaf is obtained.

Embodiment 3

[0049] A kind of preparation method of the bamboo leaf extract of present embodiment comprises the steps:

[0050] (1) Clean the green bamboo leaves, dry them at 65°C to constant weight, and then pulverize them, and pass through a 150-mesh sieve;

[0051] (2) Add absolute ethanol and ultrasonically extract twice, the ultrasonic frequency is 30-50kv, the ratio of solid to liquid is 1:20, 1:15, the extraction temperature is 50°C, the extraction time is 30min, filter and combine the filtrate , concentrated and dried in vacuum to obtain the extract of bamboo leaves.

Abstract

The invention relates to a bambusa textilis leaf extract, a preparation method and applications thereof. The preparation method comprises the following steps: grinding bambusa textilis leaves, adding anhydrous ethanol, carrying out ultrasonic extraction at a temperature of 50 to 70 DEG C, filtering, collecting the filtrate, condensing filtrate, and finally drying filtrate in vacuum to obtain the extract. The extract of bambusa textilis leaf is obtained by extracting bambusa textilis leaves in anhydrous ethanol under ultrasonic waves at a specific temperature, collecting liquid extract, condensing and drying; and the animal experiment results have show that the extract can reduce cholesterol, prevent oxidation in human body, and reduce blood fat.

Description

technical field [0001] The invention relates to the preparation of bamboo leaf extract, in particular to the green bark bamboo leaf extract and its preparation method and application. Background technique [0002] Commonly called bamboo leaves at present mainly refer to the leaves of Gramineae Pachyphylla (i.e. bamboo). Danzhu is a species of Bamboo genus in Poaceae. It has a long history of edible and medicinal use in my country. It is a natural plant recognized and approved by the state for both medicine and food. [0003] Studies have shown that bamboo leaves contain a variety of biologically active ingredients, including flavonoids and their glycosides, active polysaccharides, amino acids, polyphenols, organic acids, etc. Bacteria and other physiological functions. [0004] As disclosed in the prior art, the preparation method and application of extracting crude extract from the branches and leaves of Gramineae Phyllostachysnigra (L-Odd.) Munrovarhenonis (Mitf) Stapfex...
