Four macrolides (ranging from dimer to pentamer) of lithocholic (3α‐hydroxy‐5β‐cholan‐24‐oic) acid were identified by electron impact and fast atom bombardment mass spectrometry and 13 C NMR spectrometry. The 13 C NMR chemical shift assignments are based on comparison with related monomeric species and DEPT experiments.
