Objective:
To research the hemostatic components of burnt Folium Nelumbinis and select a better method of processing.
Method:
The anastalsis of medicinal materials between various collection period and the main astrictive parts of burnt Folium Nelumbinis were reviewed by slide method. The powder was observed by microscopic identification. The content of alkaloid was assayed by HPLC. The new method of processing was selected by the orthogonal experiment.
Result:
The lotus leaf in terminal growth can significantly shorten the clotting time and its carbon is more significant which is consistent with other analysis results. The n-butanol part from burnt Folium Nelumbinis can significantly shorten the clotting time. The optimum processing of the new method is 140 degrees C, 20 min and its product meets relevant regulations.
Conclusion:
In preliminary view, n-butanol part from burnt Folium Nelumbinis is the main astrictive site. It is reasonable to make the lotus leaf in terminal growth into carbon. It is feasible to carbonize by muffle furnace.
