| 中文摘要: |
| 分别利用分光光度法、高效液相色谱法、气相色谱法对米糠毛油中去甲基甾醇的含量进行检测并比较。结果表明：气相色谱法测定结果更准确，重现性好，加标回收率为93.5%，相对标准偏差为1.30%，适合米糠毛油中去甲基甾醇组成及含量的测定。 |
| 英文摘要: |
| The content of desmethyl phytosterols in crude rice bran oil was detected and compared by spectrophotometry method, high-performance liquid chromatography method and gas chromatography method. The results showed that gas chromatography method was more accurate with good reproducibility comparing with the other two methods, and the recovery rate of standard addition was 93.5% and the relative standard deviation was 1.30%, which was suitable for the detection of desmethyl phytosterols in crude rice bran oil. |
