Abstract

Pristane (2,6,10,14-tetramethylpentadecane) has been isolated from two recent marine sediments. Unlike their ancient counterparts, these sediments contain no detectable phytane. These two facts suggest a biochemical origin for at least a fraction of the sedimentary pristane and a later, geochemical formation of phytane. Commercial reagent-grade solvents (pentane, isooctane, methanol) contain appreciable quantities of fossil pristane and probably phytane.

摘要

姥鲛烷（2,6,10,14-四甲基十五烷）已从最近的两份海洋沉积物中分离出来。与古代沉积物不同的是，这些沉积物中未检测到植烷。这两个事实表明，至少一部分沉积姥鲛烷有生物化学来源，而植烷是后来通过地球化学形成的。商业试剂级溶剂（戊烷、异辛烷、甲醇）含有相当数量的化石姥鲛烷，可能还含有植烷。
