采用高效液相色谱法（HPLC）分析了深海钻探工程第40航段（安哥拉海盆）、第41航段（佛得角海隆）和第43航段（百慕大海隆）沉积物中的镍、钒和游离碱卟啉。结果比较以及与以前的质谱研究。镍卟啉混合物比来自相同芯部分的钒基混合物含有更多的氧代卟啉。在一个被火山侵入热蚀变的Leg-41岩心剖面（编号386-63-2）的镍和钒基卟啉馏分中检测到高碳数卟啉（> C33），但在所有其他样品中不存在。分离的馏分的反相HPLC和随后的质谱分析揭示了一系列新的aetio卟啉，其比任何先前检测到的极性更强。
The nickel, vanadyl and free base porphyrins from sediments of Legs 40 (Angola Basin), 41 (Cape Verde Rise) and 43 (Bermuda Rise) of the Deep Sea Drilling Project were analysed by high-performance liquid chromatography (HPLC). The results compare well with previous mass spectrometric studies. Nickel porphyrin mixtures contain more aetio porphyrins than do the vanadyl mixtures from the same core section. High-carbon-number porphyrins (> C33) were detected in both nickel and vanadyl porphyrin fractions of a Leg-41 core section (No. 386-63-2) which had been thermally altered by a volcanic intrusion, but were absent in all the other samples. Preparative HPLC and subsequent mass spectrometric analyses of the isolated fractions reveal a new series of aetio porphyrins which are more polar than any previously detected.
