摘　　要：目的：制定新疆鼠尾草药材质量标准,为新疆鼠尾草的开发利用提供技术支持。方法：采集10批新疆鼠尾草药材,对这些样品的性状、检查、鉴别、指标成分含量进行了研究;以迷迭香酸为对照品,采用薄层色谱（TLC）法进行定性鉴别;采用高效液相法（HPLC）测定迷迭香酸的含量。结果：对新疆鼠尾草药材的性状、显微特征进行了描述;根据10批不同产地新疆鼠尾草的测定结果确定：新疆鼠尾草水分不得超过10%,总灰分不得超过14%,酸不溶性灰分不得超过7%,浸出物以热浸法测定,65%乙醇热浸法浸出物暂定不低于13%,水热浸法浸出物的含量不得低于15%。TLC斑点清晰,分离度好;迷迭香酸的进样量在1.001～6.006μg（r=0.999 8）与峰面积积分值呈良好线性关系,平均回收率为100.54%,RSD 1.9%,迷迭香酸含量不得少于2.0%。结论：新建标准可用于新疆鼠尾草药材的质量控制。Objective： To provide technical support for the utilization and development of Salvia deserta by establishing the quality standards. Method： Ten batches of crude drugs of S. deserta were collected. The morphology,inspection,identification and the content of target components in these samples were studied. With rosmarinic acid as the reference substance,TLC method was used for qualitative identification. The contents of rosmarinic acid were determined by HPLC. Result： Nature and microscopic characteristics of S. deserta were described. According to the measurement results of 10 batches of samples,moisture in the crude drug was not more than 10%; the content of total ash was not more than 14%; the content of acid-insolubal ash was not more than7%. The extracts were determined by hot dipping method; the content of ethanol extracts was tentatively determined not less than 13% and content of water extracts was not less than 15%. The spots in TLC were clear and well-separated. The sample size of rosmarinic acid was 1. 001-6. 006 μg（ r = 0. 999 8）,showing a good linear relationship with peak area integral value. The average recovery rate was 100. 54%,RSD 1. 9%. The content of rosmarinic acid was not less than 2. 0%. Conclusion： The newly established standard can be used for quality control of S. deserta.
