Embodiment 1

[0014] Mix sweet tea, dendrobium and Shiya tea with a weight ratio of 1:2:1, add 60v% ethanol, and the amount of ethanol added is 4 times the total weight of sweet tea, dendrobium and Shiya tea. Extract for 1 hour under ultrasonic conditions of 250 Hz, concentrate the extract to 1 / 2 of the original volume, add ethyl acetate twice the volume of the concentrate for precipitation, filter with suction, and freeze-dry the precipitate, which is the compound original tea original tea .

Embodiment 2

[0022] Mix and pulverize sweet tea, dendrobium and Shiya tea in a weight ratio of 2:2:10, add 75v% ethanol, and the amount of ethanol added is 10 times the total weight of sweet tea, dendrobium and Shiya tea. Extract under 400Hz ultrasonic conditions for 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 for precipitation, filter with suction, and freeze-dry the precipitate. It is the original compound original tea.

Embodiment 3

[0024] Mix and pulverize sweet tea, Dendrobium and Shiya tea at a weight ratio of 1:2:10, add 70v% ethanol, the amount of ethanol added is 6 times the total weight of sweet tea 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

A preparing method of rubus suavissimus-dendrobium-adinandra nitida leaf composite raw tea is disclosed. The method includes mixing rubus suavissimus, dendrobium and adinandra nitida leaves according to a weight ratio of 1-2:1-2:1-10, 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 compound raw tea, in particular to a preparation method of sweet tea, dendrobium and Shiya tea compound raw 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 c...
