采用气相色谱法，以水杨酸甲酯为内标物，测定榄香烯注射液中的有效成分β－，γ－，δ－榄香烯含量．榄香烯浓度在０．５～１．５ｍｇ／ｍＬ范围内峰面积比与浓度呈良好的线性关系，ｙ＝１．３２ｘ－０．０３，ｒ＝０．９９９９（ｎ＝５）．平均回收率１００．９％，ＲＳＤ０．５％．
The content of β, γ-, δ-elemene in the elemene injection was determined by gas chromatography with methyl salicylate as internal standard. Elemene concentration in the range of 0.5 ~ 1.5mg / mL peak area ratio showed a good linear relationship with the concentration, y = 1.32x-0.03, r = 0.9999 (n = 5). The average recovery was 100.9% and RSD 0.5%.
