摘要
目的:优选川芎和细辛挥发油的β-环糊精(β-CD)微囊萃取工艺条件。方法:选择β-CD和硫酸钠作为双水相萃取剂,以挥发油收率、甲基丁香酚和苯酞类物质(以藁本内酯计)质量的综合评分为指标,通过正交试验考察萃取液中β-环糊精和硫酸钠的质量浓度、提取方式、萃取温度对微囊萃取工艺的影响。采用GC-MS分析挥发油的组分,以邻二甲苯和邻苯二甲酸二丁酯为内标物。结果:最佳萃取工艺条件为加3倍量40%乙醇室温下浸泡24 h,60℃热浸60 min,抽滤,提取液中加入β-CD和硫酸钠至质量浓度分别为300,50 g·L-1,50℃振荡萃取30 min;挥发油收率86.54%,挥发油中甲基丁香酚和苯酞类物质(以藁本内酯计)质量分别为75.88,353.91 mg。结论:β-CD微囊双水相萃取及包合川芎和细辛挥发油的工艺合理可行,适合于采用β-CD包合的挥发油制剂工业化生产。
Objective:To optimize β-cyclodextrin (β-CD) microcapsule extraction process of volatile oil from Chuanxiong Rhizoma and Asari Radix et Rhizoma.Method:β-CD and sodium sulfate were employed as extraction agents in aqueous two-phase system,with composite score of volatile oil yield,quality of methyl eugenol and phthalides (in the content of ligustilide) as index,L9 (3^4) orthogonal test was adopted to optimize extraction and inclusion technology of volatile oil from Chuanxiong Rhizoma and Asari Radix et Rhizoma by β-CD microcapsule,the concentration of β-CD and sodium sulfate in extract,extraction methods and temperature were selected as main influence factors.Taking O-xylene and dibutyl phthalate as internal standards,components of volatile oil was analyzed by GC-MS.Result:Optimal extraction process conditions were as follows:soaked 24 h with 3 times the amount of 40% ethanol,heated to temperature of 60 ℃ and stirred for 60 min,then vacuum suction filtrated,β-CD and sodium sulfate were added to filtrate to the concentration of 300 g · L^-1 and of 50 g·L^-1,respectively; stirred and extracted for 30 min at 50 ℃.Under these conditions,vield of volatile oil was 86.54%,contents of methyl eugenol and phthalides (in the content of ligustilide) were 75.88 mg and 353.91 mg.Conclusion:Technologies for extraction and inclusion of volatile oil from Chuanxiong Rhizoma and Asari Radix et Rhizoma are feasible and suitable for industrial production of volatile oil preparations for3-CD inclusion.
