中文摘要：

目的：分析比较生黄芩和黄芩炭的鞣质含量及炭素吸附力强弱,探讨黄芩炒炭止血作用机理.方法：采用磷钼钨酸/干酪素-分光光度法及亚甲基蓝-分光光度法分析比较生黄芩及黄芩炭的鞣质含量和吸附力大小.结果：黄芩炒炭后,鞣质含量显著下降,炭素吸附力明显上升.结论：鞣质含量高低和炭素吸附力大小对黄芩炒炭止血作用的影响不尽一致,尚需结合黄芩所含化学物质的变化,深入探讨黄芩炒炭止血作用机制.

英文摘要：

Objective： To analyze the contents of tannin and the absorption capacity of carbon between Scutellaria Radix and charred Scutellaria Radix so as to explore the mechanism of the hemostatic effect of charred Seutellaria Radix. Method： Phosphotungstomolybdate acid/casein-spectrophotometry and methylene blue- spectrophotometry were adopted to compare the contents of tannin and the absorption capacity of carbon. Result： After being charred, the content of tannin significantly decreased but the absorption capacity of carbon significantly increased. Conclusion： The influence of tannin on the mechanism of the hemostatic effect of charred Scutellaria Radix was not consistent with that of the adsorption capacity of carbon. The deeply integrated research on chemical substances will be considered to clarify the mechanism of hemostatic effect of charred Scutellaria Radix.
