2、 Chemical constituents of Eupatorium adenophorum

1. the whole grass contains sugars: glucose, galactose, lycoose, stachyose, raffinose, sucrose, laceroic acid,Betulinic acid（betulinic acid)，Ursolic acid（ursolic acid)，β - sitosterol。
2. the whole grass contains volatile oil and tannin.

3、 Pharmacological action of Eupatorium adenophorum

The whole herb preparation has cardiotonic effect. Two kinds of water extracts of Eupatorium adenophorum, sweet potato seedlings and whole Eupatorium pilosum, 2g/kg intraperitoneal injection, can significantly improve the microcirculation disorder of rabbits with blood stasis caused by simulated weightlessness in space flight. 4g/kg gavage for 4G days also has a good effect on improving the abnormal Hemorheology of rabbits, so that the blood viscosity, fibrinogen content and erythrocyte aggregation index are lower than those of the control group.
