Abstract

OBJECTIVE

To investigate the effect of technologies and conditions on volatile oil yield extracted from Rhizoma Curcumae.

METHODS

Water Extraction coupling Rectification (WER) and Steam Distillation (SD) technologies were applied to extract the volatile oils based on orthogonal table L9 (3(3)) to find out optimized condition.

RESULTS

Variance and range analysis of orthogonal experiment results showed that the best conditions of WER and SD were as follows: ultrasound 0 h, extract 12 h with 8 (or 12 fold water for SD) fold water amount. Paired T test on the yields of the oils indicated that the oil yields prepared by WER and SD were significantly different. GC-MS analysis characterized 12 common compounds,which occupied 97.19% (SD) and 92.25% (WER) of the ones identified, respectively. Moreover, the relative percentage of the common constituents were almost the same.

CONCLUSION

Ultrasound is not good for extracting volatile oil from Rhizoma Curcumae. WER could not only increase the oil yield of Rhizoma Curcumae, but also keep the quality of the oils accord with that extracted by SD.

摘要

目的

考察工艺条件对莪术挥发油提取率的影响。

方法

采用水提取耦合精馏（WER）和水蒸气蒸馏（SD）技术，依据正交表L9（3³）提取挥发油以找出优化条件。

结果

正交试验结果的方差分析和极差分析表明，WER和SD的最佳条件如下：超声0小时，用水量8（SD为12倍）倍，提取12小时。对挥发油得率进行配对t检验表明，WER和SD制备的挥发油得率有显著差异。气相色谱-质谱联用（GC-MS）分析鉴定出12种共有化合物，分别占所鉴定化合物的97.19%（SD）和92.25%（WER）。此外，共有成分的相对含量几乎相同。
