Embodiment 1

[0013] Mix and pulverize sweet tea leaves and Gynostemma leaves at a weight ratio of 1:1, add 60v% ethanol, the amount of ethanol added is 4 times the total weight of sweet tea and Gynostemma pentaphyllum, and extract for 1 hour under ultrasonic conditions with a temperature of 40°C and a frequency of 250Hz. Add lime water to the extract to adjust the pH to 7.6, centrifuge, filter off the supernatant, and freeze-dry the precipitate, which is the composite original tea.

Embodiment 2

[0019] Mix and pulverize sweet tea leaves and Gynostemma leaves at a weight ratio of 1:10, add 75v% ethanol, the amount of ethanol added is 10 times the total weight of sweet tea and Gynostemma, extract 3 times under ultrasonic conditions with a temperature of 50°C and a frequency of 400Hz , 2 hours each time, combine the extracts, add lime water to the extracts to adjust the pH to 7.8, centrifuge, filter the supernatant, take the precipitate and freeze-dry it, which is the composite original tea.

Embodiment 3

[0021] Mix and pulverize sweet tea leaves and Gynostemma leaves at a weight ratio of 2:1, add 70v% ethanol, the amount of ethanol added is 6 times the total weight of sweet tea and Gynostemma, extract twice under ultrasonic conditions with a temperature of 45°C and a frequency of 300Hz , 1.5 hours each time, combine the extracts, add lime water to the extracts to adjust the pH to 7.8, centrifuge, filter the supernatant, and freeze-dry the precipitate, which is the composite original tea.

Abstract

The present invention discloses a strigose hydrangea leaf and herba gynostemmatis pentaphylli compound original tea preparation method. The strigose hydrangea leaves and the herba gynostemmatis pentaphylli are mixed at a weight ratio of (1-2):(1-10), ethanol at a concentration of 60-75v% is added, extraction is conducted under ultrasonic waves, lime water is added into the extract to adjust the pH into 7.6-7.8, the mixture is centrifuged, the supernatant is removed by filtration, and the precipitate is freeze-dried, thereby obtaining the compound original tea. The prepared compound original tea has a synergism on diabetes sugar lowering and has a certain protection function for improving diabetes complication such as abnormal lipid metabolism and kidney damage.

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 gynostemma pentaphyllum. Background technique [0002] Diabetes is a chronic life-long disease. With the improvement of people's living standards, its incidence is increasing year by year. In order to control blood sugar, long-term sugar-restricted diet and drug treatment also seriously affect the quality of life of patients. Sweet tea (Rubus Suavissmus S Lee) is the leaf of a natural sweet plant unique to Guangxi, and it is also the best sweet plant in the world with high sweetness, low heat, safety, non-toxicity and health care function. Sweet tea contains about 4.1% bioflavonoids, 18.04% sweet tea polyphenols and 5% Rubusoside. Studies have found that rubusoside can reduce the blood sugar level of normal mice, and has obvious inhibitory effect on gluconeogenesis in mice. Streptozotocin-induced hyper...
