Examples
Embodiment 1
[0029] Example 1: Preparation of Buttercup Root Extract
[0030] Take the dried Ranunculus yam tubers, crush them and immerse them in 50%-70% ethanol or acetone, keep them warm for 4 hours-6 hours; ultrasonicate for 0.5 hours; filter, and repeat the operation of the filter residue under the same conditions for a total of 3 times of leaching; combine the filtrates, and take them by centrifugation The supernatant was concentrated by distillation under reduced pressure. The concentrated solution is obtained after drying. Buttercup extract is powdery, brownish red.
Embodiment 2
[0031] Embodiment two: the identification of the extract of Ranunculus yam
[0032] Take some of the extracts of Rhizoma yam described in Example 1, dissolve them in an appropriate amount of 100% ethanol, and the concentration is 1 mg / ml; the measuring instrument is a spectrophotometer UV8500, and the continuous absorption spectrum of the hemostatic drug is measured in the visible spectrum band. There should be a characteristic absorption peak at 456nm (see attached figure 1 ).
Embodiment 3
[0033] Embodiment 3: Acute trauma hemostasis test in dogs
[0034] Choose a hybrid dog and feed it adaptively for 1 week. During the test, the dog was anesthetized, and 20% Na was applied to the chest and abdomen. 2 After S depilation, incision with a sterile scalpel is performed to cause microvessels or small blood vessels to be artificially wounded to natural bleeding; the wound is applied with the extract of Rhizoma yam, described in Example 1, and ground into powder (dried tubers of Rhizoma yam, finely ground) It was compared with yam decoction. The test shows that the yamba extract can stop the bleeding within 30 seconds, but the yamba decoction can not stop the bleeding after grinding the powder for more than 60 seconds. Statistical analysis shows that the difference in the hemostasis time is significant, suggesting that the yamba extract has a faster hemostatic speed , The effect is better.
