十全大补丸中挥发油的包合工艺研究

目的:提取十全大补丸中的挥发油,并对其进行β-环糊精(β-CD)包合工艺的研究以增强其稳定性。方法:采用水蒸汽蒸馏法提取挥发油,以包合物得率及油利用率为指标,用正交设计法优选包合物的制备工艺,得到显著影响因素为油:β-环糊精的比例。并用红外分光光度(FT-IR)法和X-射线衍射(XRD)法表征所得包合物。结果:优选出包合工艺:十全大补丸挥发油与β-CD投料比为1∶8,包合时间1.0 h,包合温度为40℃。结论:用β-环糊精对挥发油进行包合后,提高了稳定性、增加了溶解度、便于制剂。

Study on the Inclusion Technology of Volatile Oil in Shiquandabu Pills

OBJECTIVE: To extract volatile oil from Shiquandabu pills and study technological process of its inclusion compound with beta-Cyclodextrin (beta-CD) to improve its stability. METHODS: The study was carried out with steam distillation and orthogonal design. The process conditions were studied by determining the utilization and ratio of oil from Shiquandabu pills volatile oil and extract ratio of in-clusion compound. The most important factor was the ratio of oil to beta-CD. and the inclusion compound was identified by FT-IR spectra and XRD. RESULTS: The optimum preparation conditions for inclusion were best-established as oil: beta-CD was 1:8, the inclusion time and temperature were for 1.0 hours. at 20 degrees C. CONCLUSION: Tne method can be used for increasing volatile oil's stability and its solubility. It is suitable for production of medicinal preparation.
