brine shrimp Artemia salina, have been prepared from 2',4',6'-trihydroxyacetophenone. High-resolution mass spectrometric analysis has permitted elucidation of the fragmentation patterns exhibited by these systems following electron-impact ionization.
5-羟基-2-异丙基-7-甲氧基色酮(1d),一种从贝氏酵母(Baeckea frutescens)的空中部分分离出的色酮成分,以及四种类似物(1a-c和1e),它们均对卤水虾卤虫有毒,由2′,4′,6′-三羟基苯乙酮制备。高分辨率质谱分析允许阐明这些系统在电子碰撞电离后显示的碎片模式。
