Objective： the paper reports a GC method for determination of methanol in Fufangyatongding by packed column gas chromatography. Methods： GC method is adopted for the determination PQ column which is packed with Porakpak （2m × 3mm,60 × 80m）. N-propanol has been used as the internal standard substance in internal standard method. The temperature of injection port is 240℃, column temperature 140℃, and the GC system consists of FID as the detector, whose temperature is 250℃, and the sample size is 21uL. Results： Methanol got a good linearity between 0. 008 - 0. 8 uL . ml -1 under the chromatographic condition. The mean recovery was 93.3 %, and RSD was 1.92% （n =6）. The RSD of the stability test was 3.45%. Conclusion： The method is so simple, rapid and with satisfactory recoveries that it can provide the scientific quarantine criterion for fufangyatongding.
