【摘要】 目的优选类风关颗粒剂中草果、防风挥发油的提取及-βCD包合工艺。方法采用单因素变化试验,以草果、防风挥发油出油量为指标优选提取工艺;以包合物挥发油的利用率为指标优选-βCD包合工艺。结果优选挥发油提取工艺条件为:草果、防风不用提前浸泡,以饮片投料,加8倍量水,蒸馏提取6 h;包合物最佳包合工艺为:采用饱和水溶液法,挥发油用15倍量85%乙醇溶解,与-βCD的投料比为1︰8,在25℃下,超声包结30 min。结论该工艺可用于草果、防风挥发油的提取及包合。更多还原

【Abstract】 Objective To optimize the conditions for the extraction of volatile oil from Fructus Tsaoko and Radix Saposhnikoviae in Leifengguan granules,and for the preparation of their β-CD inclusion compounds.Methods With the percentages of extracted volatile oil of Fructus tsaoko and Radix saposhnikoviae as the target marker,single-element experiments were conducted to determine the optimum conditions for extracting the volatile oil.The application rate of included volatile oil was used as the target marker to optimize the conditions for including the oils with β-CD.Results The optimized extraction conditions were: with 8-fold water added,the sliced herbal medicine of Fructus tsaoko and Radix saposhnikoviae should be extracted for six hours without advanced soaking with water.The optimized inclusion conditions were: applying the saturated aqueous solution method,15-fold 85 % ethanol was used to dissolve the volatile oil,the proportion of the above solution and β-CD being 1︰8;at 25 ℃,the volatile oil was included for 30 minutes with ultrasonic wave.Conclusion The established process can be used for the extraction and the inclusion of volatile oil from Fructus Tsaoko and Radix Saposhnikoviae in Leifengguan granules.更多还原
