摘要
为阐明鲜蟾酥的化学成分以及鲜蟾酥与干蟾酥化学成分差异,本研究对黑眶蟾蜍的新鲜耳后腺分泌液及干蟾酥中的化学成分进行了比较研究。采用超高效液相色谱串联静电场轨道阱高分辨质谱(UPLCOrbitrap MS)技术,以乙腈和水(含体积比0.1%甲酸)为流动相对其进行梯度洗脱,并在高分辨质谱正离子在线检测模式下,通过比对化合物的精确分子量及质谱碎片信息对其中39个主要色谱峰进行了鉴定。鲜蟾酥及干蟾酥主要成分的化学模式存在较大差别,与干蟾酥相比,鲜蟾酥在蟾毒配基类成分上的含量低、种类少。
To identify the active components in Bufo melanostictus Schneider and clarify the difference between fresh and dried Venenum Bufonis, a UPLC-Orbitrap MS method has been established. The separation was performed with gradient elution of acetonitrile and water （with 0.1% formic acid） as mobile phase. By comparing their retention time and high resolution mass data of Venenum Bufonis extracts, 39 effective components were primarily identified by MS/MS analysis in positive ion mode. Twenty-six of them were bufadienolides. There were significant differences in the main composition between fresh and dried Venenum Bufonis. There are fewer bufadienolides in fresh toad venom.
