TITLE:
摘要: 目的:研究2-羟丙基-β-环糊精(HP-β-CD)对辛夷挥发油中桉油精溶解度的影响,并优化辛芷滴鼻剂提取工艺。方法:采用水蒸气蒸馏法提取辛夷药材中的挥发油;以辛夷挥发油中的桉油精含量为指标,采用高效液相色谱法测定不同质量浓度HP-β-CD对辛夷挥发油中桉油精溶解度的影响;以欧前胡素、浸膏得率的综合评分为指标,采用正交试验优化辛芷滴鼻剂提取工艺中乙醇用量和体积分数、提取时间,并进行验证。结果:50%的HP-β-CD水溶液可以提高桉油精溶解度至7.6倍。辛芷滴鼻剂最优提取工艺为10倍量80%乙醇,提取2次,每次1 h;验证试验中欧前胡素平均含量为0.078%(RSD=2.01%,n=3),浸膏得率为10.80%(RSD=1.85%,n=3)。结论:HP-β-CD对辛夷挥发油中桉油精具有较好的增溶作用,辛芷滴鼻剂优化提取工艺可行。
ABSTRACT: OBJECTIVE: To study the effect of HP-β-CD on solubility of 1,8-oxido-p-menthane in volatile oil of magnoliae flos, and optimize the extraction technology of Xinzhi nasal drops. METHODS: Steam distillation method was adopted to extract the volatile oil in magnoliae flos. Using the content of 1,8-oxido-p-menthane in volatile oil of magnoliae flos as index, HPLC was adopted to determine the effects of HP-β-CD with different concentration on solubility of 1,8-oxido-p-menthane in volatile oil of magnoliae flos. Using the comprehensive scores of imperatorin and extract yield as indexes, orthogonal test was used to optimize the amount of ethanol, volume fraction and extraction time in extraction technology of Xinzhi nasal drops. Verification test was carried out. RESULTS: 50% HP-β-CD aqueous solution can improve the solubility of 1,8-oxido-p-menthane to 7.6 times. The optimal extraction technology of Xinzhi nasal drops was as follow as 10-fold 80% ethanol, extracting twice, 1 h every time. In verification test, the average content of imperatorin was 0.078% (RSD=2.01%, n=3), and extract yield was 10.80% (RSD=1.85%, n=3). CONCLUSIONS: HP-β-CD shows good solubilization effect on the 1,8-oxido-p-menthane in volatile oil of magnoliae flos, and the optimized extration technology for Xinzhi nasal drops is feasible.
