Embodiment 1

[0014] Mix and pulverize Cyclocarya paliurus and Shiya tea at a weight ratio of 1:1, add 60v% ethanol, the amount of ethanol added is 4 times the total weight of Cyclocarya paliurus and Shiya tea, at a temperature of 40°C and a frequency of 250Hz Extract under ultrasonic conditions for 1 hour, concentrate the extract to 1 / 2 of the original volume, add ethyl acetate twice the volume of the concentrate to precipitate, filter with suction, and freeze-dry the precipitate, which is the composite original tea.

Embodiment 2

[0020] Mix and pulverize Cyclocarya paliurus and Shiya tea at a weight ratio of 2:1, add 75v% ethanol, the amount of ethanol added is 10 times the total weight of Cyclocarya paliurus and Shiya tea, at a temperature of 50°C and a frequency of 400Hz Under ultrasonic conditions, extract 3 times, 2 hours each time, combine the extracts, concentrate to 1 / 5 of the original volume, add ethyl acetate 3 times the volume of the concentrate to precipitate, filter with suction, and freeze-dry the precipitate, which is Compound raw tea raw tea.

Embodiment 3

[0022] Mix and pulverize Cyclocarya paliurus and Shiya tea at a weight ratio of 2:10, add 70v% ethanol, the amount of ethanol added is 6 times the total weight of Cyclocarya paliurus and Shiya tea, at a temperature of 45°C and a frequency of 300Hz Extracted twice under ultrasonic conditions, each time for 1.5h, the extracts were combined, concentrated to 1 / 3 of the original volume, added ethyl acetate 2.5 times the volume of the concentrated solution for precipitation, suction filtration, and the precipitate was freeze-dried, that is It is the compound original tea original tea.

Abstract

The invention discloses a preparation method of cyclocarya paliurus and Adinandra nitida Merr. ex H. L. Li compounded original tea. The cyclocarya paliurus and Adinandra nitida Merr. ex H. L. Li are mixed, 60-75 v% of ethanol is added, extraction is performed under the ultrasonic condition, the extracted liquid is concentrated, ethyl acetate is added to perform precipitation and suction filtration, and the precipitate undergoes freeze drying to obtain the cyclocarya paliurus and Adinandra nitida Merr. ex H. L. Li compounded original tea. The cyclocarya paliurus and Adinandra nitida Merr. ex H. L. Li compounded original tea prepared by means of the preparation method has a synergistic effect on the aspect of diabetic blood glucose reduction and also has a certain protective effect on improvement of abnormal lipid metabolism and kidney damage of diabetic complications.

Description

technical field [0001] The invention relates to a preparation method of composite raw tea, in particular to a preparation method of composite raw tea of ​​Cyclocarya paliurus and Shiya tea. Background technique [0002] Shiya tea (AdinandranitidaMerr.exH.L.Li), also known as the dry leaves of Yangtong, is rich in flavonoids and phenolic substances, and has various biological activities such as antioxidant, antibacterial, and antitumor. "Study on the Antioxidant Activity of Populus glabrata" (published in May 2013, a master's thesis of Southwest University, Zhang Jingyi) disclosed that the ethanol extract of Shiya tea was extracted with petroleum ether, ethyl acetate, and n-butanol in sequence. Afterwards, petroleum ether extract, ethyl acetate extract, and n-butanol extract were obtained after vacuum concentration and drying respectively. After testing, the content of flavonoids and polyphenols in the ethyl acetate extract was the highest. According to the principle of simi...
