In the essential oil distilled from aerial parts(flowers, leaves) of ajwain grown in Algeria, however, isothymol(50%) was found to be the dominant constituent before p-cymene,thymol, limonene and γ-terpinene. Note, however, that the nameisothymol is not well defined and might refer to both2-isopropyl-4-methylphenol and 3-isopropyl-6-methylphenol(carvacrol).
From South Indian ajwain fruits, almost purethymol has been isolated (98%), but the leaf oil was found to becomposed of monoterpenoids and sesquiterpenoids: 43% cadinene, 11%longifolene, 5% thymol, 3% camphor and others.
