摘　　要：目的采用RP—HPLC测定香茅挥发油中的橙花醛和香叶醛。方法采用水蒸气蒸馏法提取香茅挥发油，色谱柱为PhenomenexLunaC18柱（150mm×4．6mm，5μm），流动相为甲醇-水（68：32），流速0．8mL·min^-1，检测波长237nm，柱温35℃。结果橙花醛和香叶醛分别为0．0533～0．3199、0．0971～0．5823μg与峰面积呈良好的线性关系，平均回收率分别为100．2％、100．6％，RSD分别为2．07％、2．06％（n=9）。结论所用方法简便、快速，重复性好，准确度高，可作为香茅挥发油的质量控制方法。OBJECTIVE To establish a method for the determination of neral and geranial in the volatile oil from Cymbopogon citra- tus by RP - HPLC. METHODS The volatile oil was extracted by water steam distillation and HPLC analyses were performed on a Phenomenex Luna C18 column （ 150 mm × 4.6 mm,5 μm） with methanol -water （68 ： 32） as mobile phase at a flow rate of 0.8 mL· min^-1. The detection wavelength was set at 237 nm and the column temperature was maintained at 35 ℃. RESULTS There were good linear relationships for neral and geranial within the concentration range of 0. 0533 -0.3199 μg and 0. 0971 -0.5823 μg, respectively. The average recoveries of neraI and geranial were 100.2% and 100.6% with RSD of 2.07% and 2.06% （ n = 9） ,respectively. CONCLUSION The developed method is simple, rapid, reproducible and accurate, which is helpful for the quality control of the volatile oil from the herb of C. citratus.
