1、四川大学硕士学位论文栀子的生药学研究姓名:刘瑛申请学位级别:硕士专业:生药学指导教师:张浩20030401摘要减时间对样品含量有影响。随着储藏时间延长样品中含量降低,建议避光、低温保存。实验建立的测定方法精密度商、准确性好,不仅可作为栀子魏材中舔红花苷~l和器红花总营含量测定的鬻规检验方法,也可作为控制栀子制剂的质量的方法。聂、建立了提予爨专才番红芘萤类成分指纹萤谱。运用离散渡摇色谱法的梯度洗脱的方法,对药材中化学性质极其相似的番红花苷类成分取缮良好夔分裹效巢。著对三十三静撬子药楗遴幸亍了色谱分辑,在此基疆上建立了桅子、小果
2、桅子、大花栀予药材的褥红花苷类的指纹图谱和标准。结栗表磷,获建立勰指纹鬻谱麓够反映襁子药材瓣番红花昔类成分的相似性,桅子及其变种小果栀子、大花栀予样品各自的相关性好,各主要组分的含量差异较小。不同样品之间无质的差异,仅有较小的爨的差异e经过分孝厅,所建立的攒纹图谱符合《中药注射烈指纹圈谱研究豹技术要求》,可以作为栀子质蹩控制标准的参考。关键词:栀子;小果栀子;大花栀予;番红花苷;桅子苷;HPLC;指纹餮落.一堡茎一一————————————————————————————————————————————————————一。P
