Abstract

A preparing method of grosvenor momordica fruit-dendrobium-adinandra nitida leaf composite raw tea is disclosed. The method includes mixing grosvenor momordica fruit, 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 composite raw tea, in particular to a preparation method of composite raw tea of ​​Luo Han Guo, Dendrobium 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 ...
