Actinidia arguta Sieb.et Zucc leaf tea hypoglycemic effect of the present invention is tested:
Prepared by sample: accurately weigh leaf tea (embodiment 1 sample and embodiment 2 sample respectively account for half) 10.0g, puts into beaker, adds 200mL, 90 DEG C of distilled water, and insulation is placed 15 minutes, filters.Again adding 200mL, 90 DEG C of distilled water in tea grounds, insulation is placed 15 minutes, filters.Twice filtrate merges, and concentrates, standby.
The foundation of alloxan diabetes mouse model: mice adaptability feeds 3d, during modeling, water 12h is can't help in mice fasting, disposable celiac injection alloxan 200mg/kg, (being made into mass fraction 2% solution with normal saline) ad lib afterwards, tail venous blood sampling after 72h, measure blood glucose value, take blood glucose value ＞ 11.1mmol/L person for model successfully mice.
Experimental technique: modeling success mice is randomly divided into 5 groups, often group 10, i.e. being divided into dosage group (400mg/kg), Actinidia arguta Sieb.et Zucc leaf tea high dose group (800mg/kg) in hyperglycemia model group (gavage equivalent distilled water), positive drug control group (100mg/kg metformin hydrochloride), Actinidia arguta Sieb.et Zucc leaf tea low dose group (200mg/kg), Actinidia arguta Sieb.et Zucc leaf tea, separately taking 10 healthy mices is blank group (gavage equivalent distilled water).Each group press 10mL/kg and is administered, every day gavage once, continuous 28d, experiment terminates mensuration blood glucose.
Blood sugar detection uses glucose-peroxidase method, fasting 12 hours before blood sugar detection.
Experimental result: be shown in Table 1.
The impact on blood glucose in diabetic mice of the table 1 Actinidia arguta Sieb.et Zucc leaf tea
Note: the entirely different person of lower case is significant difference (P ＜ 0.05)；The entirely different person of capitalization is significant difference (P ＜ 0.05).
Interpretation of result: Actinidia arguta Sieb.et Zucc leaf tea, the most middle and high dosage is notable on mouse blood sugar impact, has blood sugar reducing function, and hypoglycemic effect is proportionate with taking dose.Actinidia arguta Sieb.et Zucc leaf tea hypoglycemic effect is more weak compared with positive drug metformin hydrochloride, and difference is extremely notable, therefore cannot function as the drug use of replacement therapy diabetes, but can assistant hypoglycemic.
