Qualitative and quantitative analysis of salidroside and p-tyrosol in Hongjingtian Injection / 中成药

AIM:To establish the qualitative and quantitative analysis of salidroside and p-tyrosol in Hongjingtian Injection(Radix et Rhizoma Khodiolae crenulatae).METHODS:The identification of salidroside and p-tyrosol were performed by TLC.Two components were determined by HPLC.RESULTS:The TLC method was suitable for the identification of salidroside and p-tyrosol with good reproducibility.The average recoveries of salidroside and p-tyrosol were 97.6% and 99.1% with RSD of 1.10% and 2.69%(n=5),respectively.CONCLUSION:This convenient,sensitive,reliable method can be used as qualitative and quantitative analysis of salidroside and p-tyrosol in Hongjingtian Injection.
