摘要: 采用HPLC-DAD法探究唐古特大黄、掌叶大黄和药用大黄种子中蒽醌的含量,测定大黄种子中芦荟大黄素、大黄酸、大黄素、大黄素甲醚、大黄酚的含量,色谱柱为Agilent Eclipse plus C18(4.6×250 mm,5 μm);流动相A相为甲醇,B相为0.1%冰乙酸溶液;柱温25 ℃;检测波长254 nm。结果发现大黄种子中含有大黄素、大黄素甲醚和大黄酚,且含量丰富,但未检测出芦荟大黄素和大黄酸。总蒽醌的含量顺序为掌叶大黄种子>唐古特大黄种子>药用大黄种子。测定方法精密度、准确度、稳定性均符合生物样品测定要求,可用于大黄种子蒽醌含量的测定。

Abstract: The aim of this study was to explore the concentrations of anthraquinone derivatives detected in Rheum tanguticum Maxim.ex Balf.seeds, R.palmatum Linn.seeds and R.officinale Baill.seeds.The contents of aloe-emodin,rhein,emodin,emodin,chrysophanol in rhubarb seeds were determined by highperformance liquid chromatography (HPLC).Agilent Eclipse plus C18 (4.6×250 mm,5 μm) column was used for chromatographic separation with the mobile phase consisting of methanol (A) and 0.1% acetic acid (B) in a gradient elution mode.Column temperature was 25 ℃;Detection wavelength was 254 nm.The results showed that the order of content of concentrations of anthraquinone derivatives was Rh palmatum Linn.seeds > Rheum tanguticum Maxim.ex Balf.seeds > Rh.officinale Baill.seeds.Rhubarb seeds contain abundant emodin,emodin and chrysophanol,excluding aloe-emodin and rhein.The developed method was proved to be accurate,precise,stable and suitable for the determination of anthraquinone derivatives in Rhubarb seeds.

Key words: Rhubarb seeds, HPLC-DAD, anthraquinone derivatives
