Vernolic acid has been found at the 30.1% level in Centratherum ritchiei (Compositae) seed oil. This acid, cis ‐12, 13‐epoxyoctadec‐ cis ‐9‐enoic, was isolated by preparative TLC and characterized by IR, NMR and MS. A successful attempt has been made to identify vernolic acid, without its derivatization, by mass spectral study. A reference vernolic acid ( Vernonia anthelmintica seed oil) has been used for comparison purpose throughout the study.
