n.[化]植烷
Typical markers are the porphyrins, pristine, phytane, steranes, carotenes and pentacyclic triterpanes. 典型的标志如卟啉、姥鲛烷、植烷、留烷、胡萝卜烷、以及五环三萜烷。
The features of the biomarkers in the oil are of relatively low abundance of isoprenoidies, and no preference between pristane and phytane. 生物标志物中类异戊二烯含量较低、植烷与姥鲛烷均势；
