| Summary: | Abstract Atmospheric pressure chemical ionisation liquid chromatography/multi‐stage ion trap mass spectrometry (APCI‐LC/MS n ) has been applied to the study of intact bacteriohopanepolyols. Spectral characterisation of bacteriohopanepolyols of known structure present in bacterial extracts ( Zymomonas mobilis and a fermenter containing methanotrophs including Methylococcus capsulatus ) has revealed greater structural detail than previous liquid chromatography/mass spectrometry (LC/MS) methods and identified characteristic fragmentations indicative of numerous biohopanoid structures. Analysis of a Recent sedimentary extract from Lake Druzhby (Antarctica) has demonstrated the power of this technique to detect biohopanoids in complex samples including at least partial characterisation of previously unknown composite structures.
