Embodiment 1

[0014] Mix and crush Luo Han Guo and Shiya tea according to the weight ratio of 2:1, add 60v% ethanol, the amount of ethanol added is 4 times the total weight of Luo Han Guo and Shiya tea, and extract under ultrasonic conditions with a temperature of 40 ° C and a frequency of 250 Hz 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 Luo Han Guo and Shiya tea according to the weight ratio of 1:1, add 75v% ethanol, the amount of ethanol added is 10 times the total weight of Luo Han Guo and Shiya tea, and extract under ultrasonic conditions with a temperature of 50 ° C and a frequency of 400 Hz 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 and pulverize Luo Han Guo and Shiya tea at a weight ratio of 5:1, add 70v% ethanol, the amount of ethanol added is 6 times the total weight of Luo Han Guo and Shiya tea, and extract under ultrasonic conditions at 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

The invention discloses a preparation method of momordica grosvenori and adinandra nitida composite original tea. The preparation method comprises the steps of mixing the momordica grosvenori and the adinandra nitida according to the weight ratio of (1 to 2) : (1 to 10), adding 60 to 75 v% of ethyl alcohol, extracting under an ultrasonic condition, concentrating an extracting solution, adding ethyl acetate for precipitation, performing suction filtration, taking the sediment for performing freeze drying, then the composite original tea is obtained. The composite original tea prepared by the invention not only has the synergistic effect of reducing blood glucose of diabetes, but also has a certain protective effect of improving diabetic complications of dyslipidemia and kidney injury.

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 ​​Luo Han Guo 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 comp...
