摘要
目的:以亳州芍花为原料,用水蒸气蒸馏法提取芍花精油,以期得到水蒸气蒸馏法提取芍花精油的最佳工艺。方法:考察不同的水蒸气蒸馏方式及原料处理方式对芍花精油提取率及精油质量的影响。结果:通过对比不同蒸馏方式以及不同原料的处理方法提取芍花精油的提取率及精油质量,得出《中华人民共和国药典》中的挥发油测定法是最佳的提取方式;原料加氯化钠处理能提高精油提取率和精油质量;另外,花蕾期芍花且阴干芍花的提取率最高。结论:该研究为水蒸气蒸馏法提取芍花精油提供了重要的技术支持,同时明确了芍花的最佳采摘期和最佳保存方法。
Objective:To get the best steam distillation technology of essential oil extraction by adopting the flowers of the Bozhou peony as raw material.Methods:The oil extraction rates and the quality had been compared among the different methods of steam distillation and the treatments of different materials.Results:The results showed that the best way was the distillated-oil determination in Chinese Pharmacopoeia;the addition of Sodium Chloride to the materials could improve the oil extraction rate and the quality with the highest oil extraction rate from the peony in the bud stage dried in the shade.Conclusion:The research provides the important technical supports for steam distillation to extract essential oil from the peony.Meanwhile the best harvest time and the best preservation method are determined.
