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 than 7%. 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.
