不同产地八角枫根及须根的水分和浸出物的含量测定

The Determ ination of Moisture and Extracts form Dry root Alangium chinense and Alangium platanifolium of different producing area

目的：测定不同产地八角枫根及须根的水分以及浸出物的含量,为制定其质量标准提供科学依据。方法：按《中国药典》2010年版Ⅰ部附录IX H中水分测定法（甲苯法）和附录X A中的浸出物测定法测定。结果：不同产地八角枫根的水分含量在9.33%~11.66%之间,须根的水分含量在10.33%~12.00%之间;根水冷浸出物含量在6.93%~10.24%,水热浸出物含量在7.04%~13.01%,醇溶性浸出物含量在8.36%~12.77%,挥发性醚浸出物含量在0.13%~0.34%;须根水冷浸出物含量在7.48%~12.48%,水热浸出物含量在9.63%~16.49%,醇溶性浸出物含量在9.50%~16.62%,挥发性醚浸出物含量0.24%~0.62%。结论：建议八角枫根的水分不超过11.10%,须根水分不超过11.49%;根水冷浸出物量不低于6.46%,水热浸出物量不低于8.59%,醇溶性浸出物量不低于8.91%,挥发性醚浸出物量不低于0.12%;须根水冷浸出物量不低于8.45%,水热浸出物量不低于11.03%,醇溶性浸出物量不低于10.20%,挥发性醚浸出物量不低于0.29%。所得结果为完善药材标准提供了科学依据。

Objective：To determine Moisture and Extracts form Dry root Alangium chinense and Alangium platanifolium for establish the quality standards provide scientific basis.Methods：Samples were determined according to the procedures recorded in the Appendix IXK and XA of Chinese Pharmacopoeia published in 2010,for moisture extracts determ ination respectively.Results：The moisture content of different regions of Chinese alangium root was in 1.51% between 7.92%,Fibrous root of the moisture content is between 10.33% and 12.00%;The root water of extract content at 6.93%~10.24%,and the water thermal extract content at 7.04%~13.01%,Alcohol soluble extract content at 8.36%~12.77%,volatile ether extract content at 0.13%~0.34%;Fibrous root water extract content at 7.48%~12.48%,and the water thermal extract content at 9.63%~16.49%,the ethanol extract content at 9.50%~16.62%,the quantity of volatile ether extract was 0.24%~0.62%.Conclusion：The Suggestions of Chinese alangium root of moisture was no more than 11.10%,Fibrous root water was less than 11.49%;Root water extract was higher than 6.46%,water thermal extract amount not less than 8.59%,ethanol extract was higher no less than 8.91%,that of ether extract w as higher than 0.12%;The fibrous root of Water extract amount was higher than 8.45%,the content of water extract with hot soak was higher no less than 11.03%,ethanol extract was higher no less than 10.20%,that of ether extract w as higher than 0.29%.The results to improve the quality of medicinal materials standard provides a scientific basis for experiment.
