Abstract:
Objective:To establish a method for the determination of atractylodin, magnolol and honokiol in Xiangshapingwei pills by GC. Methods:An HP-5 column (30 m × 0. 32 mm × 0. 25 μm) with an FID detector was used, and the flow rate of the carrier gas (N2) was 2. 0 ml·min-1. The column temperature was raised by program: the initial temperature was 100℃ and maintained for 7 min, and then raised to 250℃ at the rate of 20℃·min-1 and kept for 10min. The inlet temperature was 300℃ and the detector tem-perature was 300℃. The injection volume was 1 μl and the split ratio was 20∶ 1. Results:The linear range of atractylodin, magnolol and honokiol was 4. 264-85. 280 μg·ml-1(r=0. 999 7), 9. 856-197. 120 μg·ml-1(r=0. 999 5) and 10. 040-200. 800 μg·ml-1 (r=0. 999 6), respectively. The average recovery wsa 98. 2%, 98. 6% and 99. 3% with RSD of 1. 5%, 1. 5% and 1. 9%, respec-tively (n=6). Conclusion:The method is simple, accurate and reliable, which can be used for the quality control of Xiangshaping-wei pills.
