Abstract:
OBJECTIVE:To establish a method for simultaneous determination of α-pinene,β-pinene and linalool in volatile oil of Hedychium flavum. METHODS:The volatile oil was extracted from H. flavum according to steam distillation stated in Chinese Pharmacopoeia(2015 edition volume Ⅳ). GC method was adopted to determine the content. The determination was performed on HP-5 capillary chromatographic column(30 m×0.032 mm×0.25 μm)with hydrogen flame ion detector(FID),nitrogen gas as carrier gas,with injector temperature of 200 ℃,and detector temperature of 250 ℃,column flow rate of 0.8 mL/min, samples size of 1 μL and split ratio of 40:1 by programmed temperature. RESULTS:The linear range of α-pinene,β-pinene and linalool were 0.090 5-2.413 3 mg/mL(r=0.999 9),0.098 3-2.620 0 mg/mL(r=0.999 9),0.169 1-4.510 0 mg/mL(r=0.999 8), respectively. RSDs of precision,stability(12 h),reproducibility tests were no more than 2.0%(n=6). The average recoveries were 99.84%(RSD=0.49%,n=6),100.24%(RSD=1.38%,n=6),99.41%(RSD=1.67%,n=6),respectively.The contents of α-pinene,β-pinene and linalool ranged 0.214 4-1.325 0,0.766 2-3.172 1,0.357 4-1.518 7 mg/g in volatile oil from 23 batches of H. flavum produced in Guizhou province. CONCLUSIONS:The method established in this experiment is rapid,simple and accurate.It can be used for the content determination of α-pinene,β-pinene and linalool in volatile oil from H.flavum.
