“…In addition, it contained alkanes and fatty acids (docosane, tricosane, tetracosane, pentacosane; linoleic and octadecanoic acids) that were not found in the oil from the Brazil sample [ 25 ]. Noteworthy, precipitation, temperature, and plant age influenced, to some extent, the content and the chemical composition of the EO isolated from leaves of L. dulcis collected in Amazonia [ 26 ]. The EO content varied from 0.1 to 0.5%, whereas the composition did not change significantly with the seasons.…”

“…The main constituents were epi -α-bisabolol and hernandulcin ( 1 ), whose concentration reached its peak in the dry season, characterized by mild temperatures and the juvenile stage of plant growth. Instead, the highest amounts of epi -α-bisabolol were detected in the hottest and wettest months [ 26 ].…”

In this investigation, we have analyzed for the first time the essential oils (EOs) isolated by steam distillation of the leaves and flowers of Lippia dulcis Trevir., grown at three different locations in southern Ecuador: the Catacocha canton (Ca), the Vilcabamba parish (Vi), and the Chuquiribamba parish (Ch). Around 98.5% of the oils’ constituents were identified by Gas Chromatography-Mass Spectrometry (GC-MS) and Gas Chromatography-Flame Ionization Detector (GC-FID) analysis using a DB-5ms capillary column. Sesquiterpene hydrocarbons were predominant in the EOs (79.77, 78.22, and 76.51%, respectively). The most representative constituents of the sample from the Ca canton were β-cedrene (16.75%), δ-selinene (11.04%), and β-cubebene (12.09%), while the sample from the Vi parish was characterized by the abundant presence of β-cedrene (17.9%), δ-selinene (12.52%), and bicyclogermacrene (11.34%). β-Cedrene (18.89%), δ-selinene (11.78%), and δ-cadinene (11.07%) were the main constituents of the essential oil (EO) from the Ch parish. The likely occurrence of low amounts of thermolabile hernandulcin in the volatile oils was indicated by the presence of the fragmentation products 6-methyl-5-hepten-2-one and 3-methyl-2-ciclohexen-1-one. In summary, the study gave us a clue to the variability of Lippia dulcis chemotypes depending on the collection sites.

Quantitative analysis and identification of oils were performed by gas chromatography according to Germano et al (2022). The essential oil concentration (%) was the weight of the oil mg/100 mg of leaf dry weight, and the essential oil yield was expressed in mg/plant.…”

Lippia dulcis is a medicinal species used by communities in the Amazon region for the control of diabetes and as a tranquilizer. The objective of this study was to evaluate the plant biomass production, antioxidant defense, and chemical profi les of the phenolic compounds and essential oil of plants grown under diff erent doses of cattle, quail, and chicken manure. Chicken and quail manure at a dose of 6 kg m -2 reached the highest values of dry weight and essential oil yield of the leaves and positively infl uenced bisabolol production. Cattle manure aff ected the content and yield of the essential oil of the infl orescences, the antioxidant defense performance, and the chemical composition of phenolic compounds and essential oil. Plants grown with cattle manure showed a linear increase in the amounts of these substances with increasing dose. Chicken and quail manure led to the highest values of these components at doses between 0 and 3 kg m -2 . The evaluation of phenolic compounds and antioxidant defense showed the highest values at doses of 0, 1.5, and 3 kg m -2 , regardless of the manure used. The essential oil concentration was higher in the infl orescences, and its total yield was higher in the leaves. The chemical composition varied between these vegetative organs.
