Embodiment 4
Have the hypoglycemic activity of the total triterpenoid extract of inonotus obliquus of hypoglycemic activity to the hyperglycemia mice
Mode inducing mouse by the lumbar injection alloxan produces diabetic symptom.Behind the injection alloxan hydrate 72h, measure the blood glucose value (blood derives from mouse tail vein) of mice with test kit, the mice that blood glucose value is higher than 11.1mmol/L is divided into 4 groups at random, 8 every group.First group is the diabetic mice contrast; Second group is the positive contrast medicine of glibenclamide group; The 3rd group is the total triterpenoid extract of inonotus obliquus with hypoglycemic activity of the present invention, and be that the total triterpenoid extract of inonotus obliquus with reducing blood sugar and blood fat effect is raised in the mice filling every day.The 4th group is the normal mouse matched group, every day normal diet.Testing sample all with 0.4% sodium carboxymethyl cellulose (CMC-Na) aqueous solution suspendible after, by irritating the stomach pin sample solution is poured into the mice gastric by force, first group and irritate the 4th group of every day and raise the CMC-Na aqueous solution.Write down diet, drinking-water and body weight every day.Irritate after the stomach 20 days, get blood until dead mouse, immediately mice is dissected then, take out liver, thymus and spleen rapidly and weigh from eyeball of mouse.The centrifugal acquisition serum of mouse blood is measured blood sugar content, total cholesterol level, content of triglyceride, hdl concentration and Mouse Liver glycogen content in the mice serum.
The result shows, the inductive diabetic mice polydipsia of alloxan, polyphagia, poor growth, spleen index and thymus index are lower than normal group mice, and the total triterpenoid extract of inonotus obliquus with hypoglycemic activity can effectively improve the diabetic mice polydipsia, the symptom of polyphagia, body weight, spleen index and thymus index all increase to some extent than diabetic model group.
As shown in table 1, the lumbar injection alloxan causes the blood sugar level of diabetic mice to increase more than 2 times.The total triterpenoid extract of inonotus obliquus that the filling stomach has hypoglycemic activity is after 20 days, and fasting blood glucose level has had reduction (p＜0.01) significantly, and fasting blood sugar is reduced to 3.96mmol/L from initial 10.26mmol/L.The hepatic glycogen content of total triterpenoid extract of inonotus obliquus mice with hypoglycemic activity illustrates that than diabetic model group height the total triterpenoid extract of inonotus obliquus with hypoglycemic activity can promote the conversion of blood glucose to liver glycogen.
Table 1 has the influence of the total triterpenoid extract of inonotus obliquus of hypoglycemic activity to blood glucose in diabetic mice level and hepatic glycogen content
Compare with diabetic model group ##:p＜0.01; Compare with the normal control group *: p＜0.01
The result who measures blood lipid level shows that the total cholesterol level of diabetic model group mice, content of triglyceride are than normal control group height, and hdl concentration is lower than normal control group.After the filling stomach had the total triterpenoid extract of inonotus obliquus of hypoglycemic activity, total cholesterol level, the content of triglyceride of diabetic mice decreased, and hdl concentration obviously increases (p＜0.05), increases to 1.77mmol/L from 1.02mmol/L.These data show that the total triterpenoid extract of inonotus obliquus with hypoglycemic activity has good effect for reducing blood fat to diabetic mice.
Table 2 has the influence of the total triterpenoid extract of inonotus obliquus of hypoglycemic activity to the diabetic mice blood lipid level
