摘要: 采用毛细管气相色谱法测定糠蜡提取物中的二十八烷醇和三十烷醇的含量。结果表明,在HP-5柱上,二十八烷醇、三十烷醇与其它种类高碳脂肪醇和内标物三苯基苯之间有较好的分离效果。方法的线性范围均为100~900mg/ml。该法简便、准确性和精密度好,对同一试样的4次平行独立测定的相对标准偏差(RSD)分别为0.86%和0.76%。

Abstract: A method for quantitative analysis of octacosanol and tricontano l i n extracts of higher fatty alcohols by gas chromatography. The sample were dete rmined in HP-5 column, triphenyl benzole (TPB) was used as the internal standar dThe calibration curves of octacosanol and tiacontanol were linear over a ran g e from 100mg/ml to 900mg/ml with a correlation coefficients of 0.992The mean c oefficients of variation for octacosanol and tiacontanol were 0.86%和0.76% re spectively
