Objective To establish and study the quality standard for Qingxin′anshenguiren Tea.Methods Spinosin,jujubaside A,jujubaside B,Poria cocos and Dried Longan Pulpin the preparation were identified by TLC,respectively.HPLC was used to determine the content of spinosin.The analytical column was Intersil C18 column(250 mm×4.6 mm,5.0μm).The mobile phase was composed of acetonitrile-H2 O(12∶88)in a gradient elution mode,and the detection wavelength was set at 335 nm.Results The TLC of spinosin,jujubaside A,jujubaside B,Poria cocos and Dried Longan Pulpshowed good specificity.The spinosin regression equation was y=429 563 x-236 697,and r=0.999 6,in the concentration range of 3.10~620.00μg·mL-1.And the average recovery was 96.07% with RSD was 1.39%.The spinosin content in 3 batchs of the preparations was 90.60μg·g-1 and RSD was1.34%.Conclusion The standard can be used for the preparation quality control.
