[Method] Spine date seed oil was extracted by supercritical carbon dioxide extraction technology. And then the molecular distillation technology was used to reduce the acid value and peroxide value of spine date seed oil. Activated carbon and carclazyte were used to process the decolorization and deodorization treatment using the absorption characteristics. [Result] The light yellow, clear pine date seed oil with shallow taste was obtained, which had an acid value of 2.03 mg/g, peroxide value of 4 mmol/kg; the GC indicated that the oil contained 5.00% of palmitic acid, 2.00% of stearic acid, 40.46% of oleic acid, 47.72% of linoleic acid and 0.39% of linolenic. [Conclusion] The obtained spine date seed oil basically conformed to the national edible oil standard and could be used as edible oil, but its pharmacological properties needed further study.展开更多
目的：建立复方酸枣仁膏质量标准。方法：采用TLC法鉴别川芎、甘草;采用HPLC法测定本制剂中阿魏酸的含量。色谱条件：流动相为甲醇-水-冰醋酸（22∶78∶1）,检测波长为323 nm,流速为0.6 m L/min;柱温为室温。结果：采用的薄层色谱斑点清...目的：建立复方酸枣仁膏质量标准。方法：采用TLC法鉴别川芎、甘草;采用HPLC法测定本制剂中阿魏酸的含量。色谱条件：流动相为甲醇-水-冰醋酸（22∶78∶1）,检测波长为323 nm,流速为0.6 m L/min;柱温为室温。结果：采用的薄层色谱斑点清晰,分离度较好,阴性无干扰。HPLC法检测阿魏酸的线性范围为0.02650~0.47670μg,平均回收率为96.81%。结论：本实验方法简单,重复性好,可进行定性、定量检测,用于复方酸枣仁膏的质量控制。展开更多
