炒南葶苈子饮片的质量标准研究

Study on Quality Standard of Semen Descurainiae Tostum

摘要:

目的 :制定炒南葶苈子饮片的质量标准,为2010年版药典质量标准提供依据。 方法 :按照2005版药典附录规定进行了炒南葶苈子饮片的HPLC含量测定方法和薄层色谱鉴别研究。 结果 :11批炒南葶苈子饮片中槲皮素-3-O-β-D-葡萄糖-7-O-β-D-龙胆双糖苷的质量分数为0.076%~0.132%。薄层鉴别用聚酰胺薄膜法,展开剂为乙酸乙酯-甲醇-水(7 ∶2 ∶1),对照品获得良好分离度。 结论 :炒南葶苈子饮片中指标成分槲皮素-3-O-β-D-葡萄糖-7-O-β-D-龙胆双糖苷的质量分数不得少于0.08%,南葶苈子炒制过程对于指标成分没有影响,因此薄层色谱和高效液相质量分数上无法区别南葶苈子药材和炒制饮片。

Abstract:

Objective: To provide scientific basis for the quality standard of Semen Descurainiae Tostum in 2010 edition of Pharmacopoeia. Method: The study of TLC identification and content determination was according to the appendix of 2005 edition of Pharmacopoeia. Result: In the 11 batches of the Semen Descurainiae Tostum , the content of quercetin-3-O-β-D-glucopyranosyl-7-O-β-D-gentiobioside was in the range of 0.076%~0.132%. The reference substance was well separated in the polyamide thin-layer chromatography and the solvent system consisted of acetoacetate-methanol-water(7 ∶2 ∶1). Conclution: The content limit of quercetin-3-O-β-D-glucopyranosyl-7-O-β-D-gentiobioside was set not less than 0.08%. The Stir-Frying did not affect the content of quercetin-3-O-β-D-glucopyranosyl-7-O-β-D-gentiobioside, the indicator substance. There was no distinction in reference substance content between Semen Descurainiae and Semen Descurainiae Tostum in TLC and HPLC.
