1、目的:通過對(duì)全國36批不同產(chǎn)地市售獨(dú)活飲片質(zhì)量進(jìn)行研究與評(píng)價(jià)。并研究獨(dú)活飲片的抗氧化性作用,對(duì)比不同地域獨(dú)活飲片主要含量差異。闡述不同產(chǎn)地獨(dú)活飲片的質(zhì)量差異性,為重慶市有關(guān)部門整合中藥材資源,建立獨(dú)活飲片質(zhì)量標(biāo)準(zhǔn)提供參考依據(jù)。
方法:從全國收集36批市售獨(dú)活飲片,每個(gè)地區(qū)收集兩批,分別從醫(yī)院和藥房收集。通過對(duì)樣品總灰分,酸不溶性灰分、水分含量、水溶性浸出物、醇溶性浸出物、蛇床子素和二氫歐山芹醇當(dāng)歸酸酯含量測(cè)定(HPLC法)以及
2、獨(dú)活飲片外形特點(diǎn)、薄層色譜鑒別、獨(dú)活飲片抗氧化性研究(MDA, SOD試劑法)并進(jìn)行對(duì)比研究。
結(jié)果:2010版《中國藥典》收錄的獨(dú)活正品為重齒毛當(dāng)歸。根據(jù)本實(shí)驗(yàn)研究可知:36批的活飲片含水量分別為:10.63%,9.78%,10.13%,9.25%,10.24%,10.02%,10.64%,9.42%,9.36%,11.12%,10.03%,9.67%,10.25%,7.38%,8.26%,8.14%,10.27%,9.23
