“…No ar-curcumene was detected in Ivorian flower essential oils but some samples were characterized by high thymol percentages, ranging from 21.6% to 34.3%. Such high levels have been reported elsewhere [24], where (E)-β-caryophyllene (25.9-36.6%) and α-humulene (9.9-19.9%) were also the major constituents. Leaf (L) essential oils: Up to 99.1% of the total components were identified in the leaf essential oils.…”

“…Unlike the leaves and flowers, there is less scientific data on the composition of essential oils obtained from L. camara fruits and stems. The composition of fruit essential oils seems to vary a lot as palmitic acid was the major constituent in south China (22.5%) [15] and Northern India (22.8%) [10], while that compound was absent from Ivorian samples from Adzope and Toumodi, which contained high proportions of (E)-β-caryophyllene and α-humulene [24]. Stem essential oils were dominated by germacrene D (31%) in south China [15] and by palmitic acid (32.7%) in Northern India [10].…”

“…The major compounds reported were sesquiterpenes, such as (E)-β-caryophyllene, α-humulene, davanone, and germacrene D [15,[21][22][23]. Some monoterpenes were also found in high proportions, such as thymol, sabinene, and limonene [24][25][26].…”

“…In a previous paper, we highlighted that essential oils produced from Ivorian L. camara constitute a new chemotype with high thymol contents, in comparison with essential oils hydrodistillated from L. camara growing in other countries [24]. However, although L. camara essential oils are widely used in traditional medicine, there is no data available on the impact of the variability due to phenological stage on essential oil compositions.…”

This work aims to study the variations in the composition of Lantana camara leaf, flower, and stem essential oils over two years. L. camara organs were harvested in Bregbo (East Côte d’Ivoire) each month from June 2015 to June 2017. The essential oils were obtained by hydrodistillation and characterized by GC-MS and 13C NMR. Eighty-four compounds accounting for 84.4–99.1% of the essential oils have been identified. The essential oils hydrodistillated from L. camara are dominated by sesquiterpenes such as (E)-β-caryophyllene and α-humulene, which were found in all samples. Some monoterpenes such as thymol, sabinene, and α-pinene were also present. Statistical analysis (principal component analysis and clustering) revealed a high variability in essential oil composition between the different organs and also within the studied periods, as the thymol proportion was higher during flowering and fruiting months. In addition, the stem, flower, and fruit essential oils were more concentrated in thymol than the leaf essential oils. The proportions of (E)-β-caryophyllene and α-humulene were strictly inverted with the thymol proportion throughout the harvest period or vegetative cycle. The antioxidant, anti-inflammatory and insecticidal activities of leaves and flowers essential oils were also studied. Results showed that L. camara leaf and flower essential oils displayed high antioxidant, anti-inflammatory and insecticidal activities.

“…Lantana camara has several subspecies and numerous ornamental cultivars [71,72] and as such, the volatile phytochemistry has shown wide variation [65] . In order to place the volatile phytochemistry of the specimens from Vietnam into perspective, a hierarchical cluster analysis (HCA) was carried out comparing the major (37) essential oil components of 60 essential oil compositions reported in the literature [65,66,73–117] along with the four specimens from Vietnam ( Figure 1). The cluster analysis reveals five clusters and one outlier.…”

Lantana camara is a troublesome invasive plant introduced to many tropical regions, including Southeast Asia. However, the plant does hold promise as a source of essential oils that may be explored for potential use. Fresh water snails such as Pomacea canaliculata, Gyraulus convexiusculus, and Tarebia granifera can be problematic agricultural pests as well as hosts for parasitic worms. Aedes and Culex mosquitoes are notorious vectors of numerous viral pathogens. Control of these vectors is of utmost importance. In this work, the essential oil compositions, molluscicidal, and mosquito larvicidal activities of four collections of L. camara from north‐central Vietnam have been investigated. The sesquiterpene‐rich L. camara essential oils showed wide variation in their compositions, not only compared to essential oils from other geographical locations (at least six possible chemotypes), but also between the four samples from Vietnam. L. camara essential oils showed molluscicidal activities comparable to the positive control, tea saponin, as well as other botanical agents. The median lethal concentrations (LC50) against the snails were 23.6–40.2 μg/mL (P. canaliculata), 7.9–29.6 μg/mL (G. convexiusculus), and 15.0–29.6 μg/mL (T. granifera). The essential oils showed good mosquito larvicidal activities with 24‐h LC50 values of 15.1–29.0 μg/mL, 26.4–53.8 μg/mL, and 20.8–59.3 μg/mL against Ae. aegypti, Ae. albopictus, and Cx. quinquefasciatus, respectively. The essential oils were more toxic to snails and mosquito larvae than they were to the non‐target water bug, Diplonychus rusticus (24‐h LC50=103.7–162.5 μg/mL). Sesquiterpene components of the essential oils may be acting as acetylcholinesterase (AChE) inhibitors. These results suggest that the invasive plant, L. camara, may be a renewable botanical pesticidal agent.

The COVID-19 (Coronavirus Disease 19) pandemic brought on by the SARS-CoV2 outbreak (Severe Acute Respiratory Syndrome Coronavirus 2) has stimulated the exploration of various available chemical compounds that could be used to treat the infection. This has driven numerous researchers to investigate the antiviral potential of several bioactive compounds from medicinal plants due to their reduced adverse effects compared to chemicals. Some of the bioactive compounds used in folklore treatment strategies are reported as effective inhibitors against the proliferative and infective cycles of SARS-CoV2. The secondary metabolites from plants are generally used to treat various diseases due to their intact medicinal properties. The present study analyses the inhibitory potential of phytocompounds from medicinal plants like Sphaeranthus indicus, Lantana camara and Nelumbo nucifera against SARS-CoV2 by molecular docking. Ten druggable protein targets from SARS-CoV2 are docked against the phytocompounds from the selected medicinal plants. The phytocompounds Astragalin, Isoquercetin, and 5-hydroxy-7-methoxy-6-c-glycosy avone were found to have lower binding energy depicting their inhibitive potential compared with the reported inhibitors that are used in the treatment of SARS-CoV2 infection. To assess the compounds' potential as drugs, their ADMET characteristics were also examined. Sphaeranthus indicus, Lantana camara, Nelumbo nucifera six possible compounds were separately screened for ADME and toxicity characteristics, then the results were analyzed.Microsecond-level molecular dynamics simulations of both the ligands complexed with NSP15 revealed that the ligand induces allosteric effects on NSP15, which could lead to destabilization of NSP15 hexameric interface and loss of RNA binding. HighlightsExploration of anti-viral properties of bioactive compounds from Sphaeranthus indicus, Lantana camara and Nelumbo nucifera.Phytocompounds with medicinal properties used in primordial treatment options are considered for the study.Molecular docking revealed compounds with the ability to inhibit the replication and breakage of polyprotein in the SARS-CoV2 virus.Molecular dynamic simulation of NSP15 with the ligand showed the binding of ligand might lead to loss of RNA binding.
