| 摘 要： | 用超临界流体微粒化技术制备薄荷醇的微胶囊,气相色谱法分别测定微胶囊表面薄荷醇和总薄荷醇的含量,并以此计算包裹率.结果表明,用乙醇和乙醚为溶剂,薄荷醇在0.025～0.800 mg/mL浓度范围内与色谱积分面积有很好的线性关系,相关系数均接近1;所用壁材三棕榈酸甘油酯对结果没有影响.用乙醇为溶剂,薄荷醇平均回收率为100...

| Abstract: | Gas chromatography was proposed to measure the content of surface menthol and total menthol for microcapsules prepared by supercritical fluid technology,and then the encapsulation efficiency could be determined.Results showed that the concentration of menthol in either ethanol or ether in the range of 0.025~0.800 mg/mL had a good linear relation with the chromatogram results(peak areas),the correlation coefficient was close to 1.When using ethanol as the solvent,the average recovery of the method was 100.03... |
