摘　　要：目的:测定贵州产杠板归的水分、总灰分、水溶性浸出物和槲皮素的含量。方法:采集贵州省19个产地的杠板归药材,按《中华人民共和国药典》(2010年版)中水分测定法(烘干法)、灰分测定法和水溶性浸出物测定法测定各地杠板归药材中水分、灰分和浸出物,采用高效液相色谱法测定槲皮素的含量。结果:19个产地杠板归药材中水分含量为5.66%~10.47%,平均8.64%;总灰分含量为4.40%~7.79%,平均5.80%;水溶性浸出物含量为16.54%~26.82%,平均22.55%;槲皮素含量为0.17%~0.58%,平均0.38%;19批贵州产杠板归样本水分、总灰分、水溶性浸出物及槲皮素含量最高值和最低值均相差1倍以上。结论:贵州省内不同产地的杠板归质量存在较大的差异。Objective： To determine the contents of water, total ash, extracts and quercetin in Poly- goni pe^foliatii herba from Guizhou. Methods： Polygoni pe^roliatii herba were collected from 19 areas of Guizhou. The methods in the Chinese Pharmacopoeia （2010 edition） were adopted for the determi- nation of water （Appendix IX H）, ash （Appendix IX K） and water soluble extract（Appendix X A）. Quercetin contents in Polygoni peoColiatii herba were detected with HPLC. Results： In the 19 speci- mens of Polygoni peoColiatii herba, content ranges of water, total ash, water-soluble extracts and quer- cetin were 5.60% to 10.50% （average 8.65% ）, 4.4% to 7.80% （average 5.80% ）, 17.00% to 26.80% （average 22.58% ）, and 0. 17% to 0.58% （average 0.38% ） respectively. These contents varied among the 19 specimens by up to 1.0 fold between the highest and the lowest. Conclusion： There exists large differences in the contents of water, ash, water-soluble extracts and quercetin in Polygoni peoColiatii herba from different areas of Guizhou province.
