OBJECTIVE: To establish a method for the content determination of L(-)-Anabasine in different medicinal parts (stem, rhizome, fibrous root, rootlet) of Alangium chinense,and provide reference for its development and utilization. METHODS: HPLC was performed on the column of Thermo C18 with mobile phase of methanol-phosphate buffer solution (22 ∶ 78,V/V) at a flow rate of 1.0 ml/min, the detection wavelength was 259 nm, column temperature was 30 ℃; the injection volume was 10 μl. RESULTS: The linear range of L(-)-Anabasine was 0.020 62-0.257 80 μg(r=0. 999 9); the limit of quantitation was 1.7 ng, limit of detection was 0.5 ng; RSDs of precision, stability and reproducibility tests were lower than 2%; recovery was 97.38%-98.86% (RSD=0.6%,n=6). The content of L(-)-Anabasine in different medicinal parts was the fibrous root>the rootlet>the rhizome>the stem. CONCLUSIONS: The method is simple, accurate, reproducible and specific, and suitable for the content determination of L(-)-Anabasine in different medicinal parts (stem, rhizome, fibrous root, rootlet) of A. Chinense.
