砂仁复方挥发油提取工艺优选研究

目的优选砂仁复方挥发油提取工艺。方法以乙酸龙脑酯收率为指标，采用气相色谱仪，运用正交设计法优选砂仁复方挥发油提取工艺备件。结果优选出的砂仁复方挥发油提取工艺为：取砂仁捣破，其他药材切成饮片，加水浸泡0．5h，加水量为药材量的96倍，采用水蒸气蒸馏法提取4h。结论采用该提取工艺提取砂仁复方挥发油有效成分乙酸龙脑酯收率较高且稳定，说明该工艺合理可行。

Study on the Extracting Process of Volatile Oil from Amomum villosum Etc

Objective To optimize the extracting process of volatile oil from Amomum villosum etc. Methods By the orthogonal design and gas chromatography,taking the rate of Bornyl Acetate as the index, we optimized the extracting process conditions of volatile oil from Amomum villosum etc. Results The optimum extracting process conditions of volatile oil from Amomum villosum etc. were that Amomum villosum was pounded to pieces, water was 96 times the weight of herbs, soaking time was half an hour and extracting time was 4 hours. Conclusion Experiment results make it clear that because the rate of bornyl acetate in volatile oil from Amomum villosum etc. by the optimum extracting process is high and stable, the extracting process of volatile oil from Amomum villosum etc. is reasonable and feasible.
