Determination of Magnolol and Honokiol Content in Health Products by Gas Chromatography Mass Spectrometry
Abstract: By ultrasound treatment, magnolol and honokiol in extraction of health products, ultimately de-termine the helium as the mobile phase. The column was DB-5 (30 m × 0.25 mm × 0.25 μm); flow rate was 1.0 ml/min; programmed temperature was 70˚C for 2 min; the temperature went up to 230˚C for 20 min with the rate of heating at 5˚C/min. Split injection was applied for sampling, where the split ratio is 50:1. This method had good separation effect, good repeatability, high recovery rate, which was consistent with the requirements of qualitative and quantitative analysis. The highest extraction rate of magnolol and honokiol in health products was obtained when the ethanol ultrasonic time is 30 min.
