    [摘要] 目的 对薏苡仁酯提取工艺进行优化，建立薏苡仁酯滴丸制备方法。 方法 以乙酸乙酯作为溶剂，以浸提次数、浸提时间、溶剂用量作为影响因素，薏苡仁酯的得率作为考察指标，采用正交试验优化提取工艺；采用滴制法制备滴丸，以聚乙二醇-6000(PEG-6000)作为基质，液体石蜡作为冷却剂，选择适当的药物基质比、药料温度、冷却温度、滴速及滴距考察滴丸的制备方法，并利用正交试验验证制备方法。 结果 薏苡仁酯的最佳提取工艺为浸提次数2次，浸提时间16 h，溶剂用量10倍，薏苡仁酯得率4.35%；滴丸制备验证结果为滴距5 cm，滴速30滴/min，药物基质比1∶3，药料温度80℃，冷却温度5℃时，滴丸的圆整度、硬度、粘连、拖尾、光泽度等外观指标均较理想，滴丸重量差异符合滴丸质量要求。 结论 薏苡仁酯提取工艺简便，滴丸制备方法操作可行。

    [Abstract] Objective To optimize the extraction process of coixendide and to establish coixendide drop pill preparation method. Methods The ethyl acetate was chosen as solvent， the number of times， extraction time and solvent usage were considered as the influence factors， and the coixenolide yield was as the index of evaluation， and the extraction process was optimized by orthogonal test. The PEG-6000 as the matrix and liquid paraffin as the coolant for preparing drop pill with the appropriate drug matrix ratio ......
