Herticins A (=(8 α H)‐10 β ‐hydroxyeremophilenolide; 1 ) and B (=(8 α H)‐6 α ,10 β ‐dihydroxyeremophilenolide; 2 ), two new sesquiterpenes, have been isolated from the AcOEt‐soluble fraction of the MeOH extract of Hertia intermedia (whole plant). Their structures were assigned from 1 H‐ and 13 C‐NMR spectra (DEPT) and 2D‐NMR analyses (COSY, NOESY, and HMBC experiments) in combination with HR‐MS experiments and comparison with literature data of related compounds.
