摘要：

An unusual class of lipid with amphiphilic properties has been detected in nodule tissue of Alnus and Ceanothus. High levels of the same lipid (20-50% of total cell lipids) were detected in solvent extracts of Frankia spp. cells. However, the lipid was absent in host roots. The lipid was purified and quantified by high-performance liquid chromatography/flame ionization detector. Phenol-sulfuric acid determinations and proton nuclear magnetic resonance indicated that the purified lipid is not a glycolipid. Mass spectra of the predominant species are consistent with published spectra for bacteriohopanetetrol (C35H62O4), a pentacyclic triterpenoid, or hopanoid.
