HPLC测定铜陵鲜姜冻干粉6-姜辣素含量
Journal of North Pharmacy(2019)
Abstract
目的:优化铜陵鲜姜渣回流提取工艺,制备铜陵鲜姜冻干粉并测定6-姜辣素含量.方法:根据2015版《中国药典》中生姜提取方法,将铜陵鲜姜分为鲜姜渣和鲜姜汁两部分,采用回流提取法提取铜陵鲜姜渣中6-姜辣素,通过正交试验优化生姜渣提取工艺;采用真空冷冻干燥法制备铜陵鲜姜冻干粉,结合高效液相色谱法测定6-姜辣素含量.结果:最佳工艺为:以80%浓度甲醇为溶剂,料液比1:50(m/V),在80℃水浴中回流提取两次,30min/次;在-45℃条件下真空干燥48h可得铜陵鲜姜冻干粉,高效液相色谱法测定出铜陵鲜姜冻干粉中6-姜辣素平均含量分别为1.53%.结论:建立了测定铜陵鲜姜冻干粉的HPLC测定方法,该法提取效率高、稳定性好,可为铜陵鲜姜的制剂开发提供理论指导.
