The main constituents found in the leaf and fine stems oil of D. eximia were α-eudesmol (80.3%) and spathulenol (5.0%). The leaf and fine stems oil of D. flagellaris was dominated by spathulenol (58.7%) and α-muurolol (6.2%); the bark oil was dominated by germacrene D (16.5%), cyperene (10.6%), α-muurolol (8.6%), humulene epoxide II (5.3%) and spathulenol (5.0%). The major components identified in the leaf and fine stems oil of D. pycnastera were spathulenol (52.2%), allo-aromadendrene (9.1%), germacrene D (7.1%) and elemol (5.1%). The leaf and fine stems oil of D. riparia contained spathulenol (46.5%), caryophyllene oxide (28.9%) and α-pinene (6.1%) as their main compounds. The leaf and fine stems oil of D. trunciflora was dominated by α-pinene (21.1%), bicyclogermacrene (17.6%), bulnesol (10.6%), spathulenol (10.5%), guaiol (8.1%), globulol (5.7%) and humulene epoxide II (5.0%); the bark oil was dominated by β-phellandrene (45.7%), guaiol (8.3%) and α-cadinol (7.4%).

Essential oil composition of peperomia serpens (Sw.) loud. / Ana Carla M. Da Silva in The journal of essential oil research, Vol. 18 N° 3 (Mai-Juin 2006)

The main compounds identifed in the hydrodistilled fresh-leaf oil were (Z)-nerolidol acetate (42.9%) and (E)-nerolidol (31.3%). The major constituents found in the SPME fresh-leaf headspace were α-humulene (49.1%) and β-caryophyllene (35.1%). The hydrodistilled dried-leaf oil was dominated by (Z)-nerolidol acetate (36.6%) and (E)-nerolidol (29.1%). It seems that the hydrolysis of α-humulene, identifed only in the SPME fresh-leaf headspace, was responsible by the appearance of (E)-nerolidol in the fresh- and dried-leaf oils, followed by isomerization and acetylation to produce (Z)-nerolidol acetate, being all the process heat provoked.

Essential oil variation in lippia glandulosa schauer / José Guilherme S. Maia in The journal of essential oil research, Vol. 17 N° 6 (Novembre-Décembre 2005)

Two chemical groups were characterized in the oils, one which was rich in thymol (46.3–78.1%), and another containing β-caryophyllene (17.3–59.4%) as the major component. In the first group the compounds p-cymene (5.1–7.2%) and β-caryophyllene (4.1–9.2%) have been associated to thymol in six of the analyzed oil samples. On the other hand, the second group showed variable association with (E)-nerolidol (0.7–23.6%), trans-α-bergamotene (0.2–19.3%), α-alaskene (3.4–16.0%), α-pinene (1.2–7.8%), α-hu-mulene (2.6–6.0%), caryophyllene oxide (1.9–6.0%) and linalool (0.9–5.0%), in the other eight oil samples, justifying the field observation concerning the plant scent variability at the same collection site and the chemical composition differentiation observed to L. glandulosa.
