specific differences were observed for particular n-alkylresorcinol homologs. Finally, the investigation of H(2) O extracts by LC/MS/MS revealed the presence of depside constituents. Whereas, in M. perennis, a mixture of mercurialis acid (=(2R)-[(E)-caffeoyl]-2-oxoglutarate) and phaselic acid (=(E)-caffeoyl-2-malate) could be detected, in M. annua solely phaselic acid was found. By comparison with synthesized
Mercurialis annua和M. perennis是用于补充医学的药用植物。在目前的工作中,建立了允许通过化学标记化合物化学区分紫花念珠菌和多年生念珠菌的分析方法。除以前发表的化合物外,从GC / MS证实了从青蒿的草药部分获得的CH(2)Cl(2)提取物中吡啶-3-甲腈和烟酰胺的排他性存在。值得注意的是,吡啶-3-甲腈首次被鉴定为天然产物。CH(2)Cl(2)提取物通过聚酰胺的进一步色谱分离产生了MeOH馏分,该馏分表现出宽谱的侧链饱和正烷基间苯二酚。尽管两种植物的正烷基间苯二酚模式相似,对于特定的正烷基间苯二酚同源物观察到一些特定的差异。最后,通过LC / MS / MS对H(2)O提取物进行的调查显示,存在后代成分。而在百日咳杆菌中,可以检测到鱼尿酸(=(2R)-[((E)-咖啡酰]]-2-氧戊二酸)和相酸(=(E--咖啡酰-2-苹果酸)的混合物仅发现了M. annua的相酸
