The invention relates to the technical field of health-care food, in particular to medicinal and edible
seedling tea and a preparation technology thereof.The medicinal and edible
seedling tea is prepared from, by weight, 30-40 parts of
ampelopsis grossedentata leaves, 8-12 parts of chicory roots, 10-15 parts of radix puerariae, 5-8 parts of folium mori, 5-10 parts of
honeysuckle flowers, 8-12 parts of fructus lycii, 5-10 parts of hawthorn fruits, 3-5 parts of poria cocos, 3-5 parts of
lotus leaves, 2-4 parts of fructus momordicae, 3-5 parts of rhizoma polygonati and 1-2 parts of
licorice roots. The method has the beneficial effects that the content of active ingredients is remarkably increased, and the content of total flavonoids reaches 328.5 mg / g and is increased by 148% compared with a traditional process; the content of dihydromyricetin is increased by 95.6%, the content of
puerarin is increased by 84.6%, and
chlorogenic acid (12.6 mg / g) is detected for the first time; the retention rates of total flavonoids and
puerarin respectively reach 82.1% and 78.9% by combining a
drying technology (hot air and
microwave), and are improved by more than 30% compared with the traditional hot
air drying technology; in a
diabetic mouse model, the fasting blood glucose of the group (1.0 g / kg / d) is reduced to 12.6 mmol / L, the
insulin sensitivity index is increased to-2.05, the blood glucose reducing effect reaches 82% (pgt, 0.05) of that of a positive
drug (
metformin), and the compound has remarkable clinical potential.
