目的对不同来源的黄连及其炮制品的水分、灰分和浸出物进行测定,为2010年版《中国药典》黄连及其炮制品制订相关的质量标准。方法按2005年版《中国药典》附录IXH水分测定法第1法、附录IXK灰分测定法、附录XA浸出物测定法测定。结果黄连原药的水分不得过14.0%,总灰分不得过5.0%,50%乙醇热浸出量不得少于18.5%;黄连饮片的水分不得过12.0%,总灰分不得过3.0%,50%乙醇热浸出量不得少于17.0%;酒黄连饮片的水分不得过10.0%,总灰分不得过3.5%,50%乙醇热浸出量不得少于17.0%;姜黄连饮片的水分不得过11.0%,总灰分不得过3.5%,50%乙醇热浸出量不得少于18.0%;萸黄连饮片的水分不得过11.0%,总灰分不得过3.5%,50%乙醇热浸出量不得少于17.0%。结论其研究结果可用于2010年版《中国药典》黄连及其炮制品质量标准的制定。
Objective To determine the moisture content, ash content and extract of Coptis chinensis Franch and its processed products from different sources and to establish the relevant quality standards for the Chinese version of Coptis chinensis and its processed products. Methods According to the 2005 edition of “Chinese Pharmacopoeia” Appendix IXH Moisture Determination Method 1, Appendix IXK ash determination method, Appendix XA extract determination. Results Coptis original drug water content of not more than 14.0%, not more than 5.0% of total ash, 50% ethanol, hot leaching amount of not less than 18.5%; Coptis water can not exceed 12.0%, total ash content of not more than 3.0%, 50% Leaching amount of not less than 17.0%; wine Coptis not more than 10.0% of the water, the total ash content of not more than 3.5%, 50% of the amount of ethanol hot-leached not less than 17.0%; Turmeric even Pieces of water must not exceed 11.0% Over 3.5%, 50% ethanol hot-leaching amount of not less than 18.0%; dogwood Pieces of water should not exceed 11.0%, the total ash content of not more than 3.5%, 50% ethanol hot-leaching amount of not less than 17.0%. Conclusion The results of this study can be used to develop the quality standards of Coptis chinensis and its processed products in the 2010 edition of “Chinese Pharmacopoeia”.
