莲房炭新老工艺的化学成分比较研究

Comparative Study on Chemical Components in Charcoal of Dry Receptacle of Nelumbo Nucifera Prepared by New and Old Processes

对莲房以新法──燃气焖煅法和传统焖煅法制成的莲房炭中所含的微量元素钙、镁含量和有机成分进行了比较研究。从实验结果表明，具有止血活性的钙、镁元素均存在，所含有机成分相同，唯鞣质的显示有所不同，新法和老法中某些样品不显鞣质反应，而有些老法的样品则显示示鞣质反应。

The contents of trace elements,calcium and magnesium,and Organic components in charcoal of dry receptacle of Nelumbo Nucifera prepared by new and old processes the flame-gas braising and forging method and,the traditional braising and forging method)were studied comparatively. As a result,both contain the two elements of calcium and magnesium with the styptic activity,and similar organic components.Only tannins reaction showed a bit of difference.Some samples by new and old processes have no tannins reaction,but other samples by old process do.
