Objective:To improve the quality standard for Mahuangzhisou capsules. Methods:A TLC method was used to identi-fy five components including Asari Radix Et Rhizoma, Schisandrae Chinensis Fructus, Fritillariae Cirrhosae Bulbus, Platycodonis Radix and Citri Exocarpium Rubrum in the capsules. An HPLC method was used to determine the content of Citri Exocarpium Rubrum. Re-sults:The TLC identification method for Asari Radix Et Rhizoma, Schisandrae Chinensis Fructus, Fritillariae Cirrhosae Bulbus, Platyc-odonis Radix and Citri Exocarpium Rubrum was established without any interference. The HPLC method for the determination of Citri Exocarpium Rubrum was established, and the linear concentration of hesperidin was 3.03-302.80 μg·ml-1(r=0.999 9), and the average recovery was 99. 80%(RSD=0. 49%,n=9). Conclusion:The new quality standard is simple and accurate, which can effec-tively control the quality of the preparation.

OBJECTIVE:To improve the quality standard of Shexiang qutong liniment. METHODS:TLC was used for qualita-tive identification of Resina draconis and Rehmannia. The determination of total solids and ether-soluble extracts in the preparation was detected. GC was used for the content determination of muscone:the column was Thermo-TG-WAXMS capillary column by programmed temperature,the detector was FID detector,the detector temperature was 250 ℃,inlet temperature was 200 ℃,carri-er gas was high purity nitrogen at a flow rate of 1.0 ml/min,split ratio was 5:1,and the injection volume was 1 μl. RESULTS:The TLC pots of R.draconis and Rehmannia were clear with good separation. The total solids in preparations were not less than 0.6%,and extracts were not less than 3.0%. The linear range of muscone concentration was 15.21-243.36 μg/ml(r=0.9998);RS-Ds of precision,stability and reproducibility tests were lower than 2%;recovery was 97.70%-99.63%(RSD=0.78%,n=6). CON-CLUSIONS:The established method can be used for the quality control of Shexiang qutong liniment.
