Abstract

The aim of this study was to compare the amount of spinosin in the 70% ethanol extracts of non-processed Zizyphi Semem (ZS) and processed ZS by roasting using a high-performance liquid chromatography equipped with photodiode array detector. Separation of the spinosin was used $SunFire^{TM}$ $C_{18}$ analytical column ($5{\mu}m$, $4.6{\times}150mm$) using two mobile phase consisting of distilled water and acetonitrile, both with 1.0% (v/v) acetic acid. The flow rate was 1.0 mL/min and injection volume was $10{\mu}L$. Calibration curve of the spinosin was y = 22339.45x+483.99 in tested concentration range ($1.28-20.00{\mu}g/mL$) and correlation coefficient was 1.0000. In non-processed ZS sample, the amount of the spinosin was 0.94 m/g, while, the amount of the marker compound in processed ZS samples were 0.66-1.10 mg/g.
