Embodiment 1

[0013] Mix and pulverize sweet tea leaves and dendrobium stems 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 dendrobium, 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 dendrobium stems 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 dendrobium, and extract 3 times under ultrasonic conditions with a temperature of 50 ° C and a frequency of 400 Hz , 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 dendrobium stems 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 dendrobium, and 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 invention discloses a preparing method of sweet-dendrobe combined raw tea, which comprises: mixing sweet tea and dendrobe in a weight ratio of (1-2): (1-10), adding 60-75v% of ethyl alcohol, extracting under ultrasonic waves, adding lime water into an extracted solvent to regulate a pH to 7.6-7.8, centrifuging, filtering supernate, freezing and drying a sediment to obtain the combined raw tea. The combined raw tea has a synergistic action in the aspect of diabetic sugar reducing, and has certain protection for diabetic complication of dyslipidemia 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 dendrobium. 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 hyperglycemia rats...
