| Aliphatic esters are the most widely represented class of compounds. 2-Methylbutyl-2-methylpropanoate (2-methylbutyl isobutyrate , 19.9-23.0%), 2-methylpropyl-2-methylpropanoate (isobutyl isobutyrate, 5.3%-12.4%) and 2-methylbutyl 2-methylbutanoate (3.4-5.6%) are the dominant esters. Terpenoid compounds made up more than 35% of the essential oil with mainly linalyl acetate (2,6-5,7%) and α-pinene (0,8-2,3%). \\ | Essential oil: Aliphatic esters are the most widely represented class of compounds. 2-Methylbutyl-2-methylpropanoate (2-methylbutyl isobutyrate , 19.9-23.0%), 2-methylpropyl-2-methylpropanoate (isobutyl isobutyrate, 5.3%-12.4%) and 2-methylbutyl 2-methylbutanoate (3.4-5.6%) are the dominant esters.

The dark blue colored chamazulene (found 0.1-4.5%) is an artifact of the steam distillation as with the flower oils of [[matricaria_chamomilla_l|German chamomile]]. \\ |

| "The oil from E. punctulatus showed a different profile from the commercial sample which mostly contained 1,8-cineole, piperitone, yomogi alcohol and pogostol. MetAlign™ successfully discriminated between the oil obtained from the two species and this data together with multivariate analysis showed that the commercial oil was similar to E. tenuifolius oil." \\ | "The oil from E. punctulatus showed a different profile from the commercial sample which mostly contained 1,8-cineole, piperitone, yomogi alcohol and pogostol.
