摘要
通过用环己酮和苯乙酮作内标物 ,对含量 80 %桉叶油中 1,8-桉叶油素含量的测定进行比较 ,结果表明 ,用苯乙酮作内标测定 ,标准偏差为 0 .2 7,变异系数为 0 .33% ,而且毒性较小 ,是较理想的内标物。
The content of 1,8-cineole in eucalyptus oil was determined using cyclohexanone or acetophenone as internal standard. Results showed that acetophenone was a good internal standard with low toxicity. The standard deviation was 0.27 and coefficient of variation was 0.33 %.
