Embodiment 1

[0014] Mix sweet tea and Shiya tea according to the weight ratio of 1:1, add 60v% ethanol, the amount of ethanol added is 4 times of the total weight of sweet tea and Shiya tea, and extract under ultrasonic conditions with a temperature of 40°C and a frequency of 250Hz After 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 to obtain the composite original tea.

Embodiment 2

[0020] Mix and pulverize sweet tea and Shiya tea according to the weight ratio of 1:10, add 75v% ethanol, the amount of ethanol added is 10 times of the total weight of sweet tea and Shiya tea, and extract under ultrasonic conditions with a temperature of 50°C and a frequency of 400Hz 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, take the precipitate and freeze-dry it, which is the composite original tea .

Embodiment 3

[0022] Mix sweet tea and Shiya tea according to the weight ratio of 2:1, add 70v% ethanol, the amount of ethanol added is 6 times of the total weight of sweet tea and Shiya tea, and extract under ultrasonic conditions with a temperature of 45°C and a frequency of 300Hz 2 times, 1.5 hours each time, combine the extracts, concentrate to 1 / 3 of the original volume, add ethyl acetate 2.5 times the volume of the concentrate to precipitate, filter with suction, and freeze-dry the precipitate, which is the compound original tea Tea.

Abstract

A preparing method of rubus suavissimus-adinandra nitida leaf composite raw tea is disclosed. The method includes mixing rubus suavissimus and adinandra nitida leaves according to a weight ratio of 1-2:1-10, adding 60-75 v% of ethanol, extracting under ultrasonic wave conditions, concentrating extract liquid, adding ethyl acetate, precipitating, performing suction filtration, and freeze-drying a precipitate to obtain the composite raw tea. The composite raw tea has synergistic effects in the field of glucose reducing for diabetes, and has certain functions of improving diabetic complications comprising dyslipidemia and liver injuries.

Description

technical field [0001] The invention relates to a preparation method of a composite raw tea, in particular to a preparation method of a composite raw tea of ​​sweet tea 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 similar co...
