Determination of sabinene in ledum terpenes from Ledum palustry L by gas chromatography / 中成药

AIM: To establish a gas chromatography method for the determination of sabinene in ledum terpenes from Ledum palustry L. METHODS: 5% SE 30 was adopted as the stationary phase, the temperature of column was set at 65 ?C and FID detector with termperature at 200 ?C . RESULTS: Sabinene in the preparation was gained satisfactory separation and assay under the chromatographic condition. The calibration curve of sabinene was good linear in the range of 0.06 0.60 mg?mL -1 . with the corelation coefficient r=0.9998(n=6) . The average recovery of sabinene was 100.3%, RSD=1.4%, (n=5) . CONCLUSION: The method is simple, highly repeatable and accurate, and it can be used to control the quality of the preparation.
