Two novel sphingoid derivatives were isolated from stromata of Epichloe typhina on timothy grass, Phleum pratense . Their structures were determined as 3-hydroxy-9-oxo-4-tetradecyl-5-oxa-1-azabicyclo[4.3.0]nonane-2-methanol and 3-hydroxy-9-oxo-4-(4 E -tetradecenyl)-5-oxa-1-azabicyclo[4.3.0]nonane-2-methanol by spectroscopic methods.

Three new phenolic acid derivatives, 1,3- O -di- trans - p -coumaroylglycerol, 1,2- O -di- trans - p -coumaroylglycerol and chokorin were isolated from stromata of Epichloe typhina on timothy plants Phleum pratense . Their structures were established by spectroscopic and chemical means.

A sterol with an aromatized B ring was isolated from stromata of Epichloe typhina growing on Phleum pratense . The structure was established as 1(10→6) abeo -ergosta-5,7,9,22-tetraen-3α-ol by spectral analysis and synthesis.
