“…Methyl cinnamate showed a broadly antifungal activity (Lima et al 2018; Prakash et al 2015), inhibited bacterial growth (Malheiro et al 2019), had a larvicidal effect (Fujiwara et al 2017), and, furthermore, exibited some potential to inhibit plant growth (Fujiwara et al 2017; Khanh et al 2008). Essential oils from plants containing a large percentage of methyl cinnamte also showed high bioactivity (Mar et al 2018; Noriega et al 2018). In addition, methyl cinnamate is considered as an alternative to synthetic chemicals because it is safer (Fujiwara et al 2017; Prakash et al 2015).…”

Herbicidal properties of the commercial formulation of methyl cinnamate, a natural compound in the invasive silver wattle (Acacia dealbata)

Plants that release molecules affecting other plants are a source of potential bioherbicides. Silver wattle (Acacia dealbata Link), considered invasive worldwide, was found to be phytotoxic to various other plant species. Combining the search for alternative bioherbicides while reducing the spread of this invader by preventing seed formation is a good potential strategy to solve both agricultural and environmental problems. This study aimed to identify nonvolatile compounds from A. dealbata flowers and explore their phytotoxicity on the germination process and seedling and plant growth of lettuce (Lactuca sativa L.), wheat (Triticum aestivum L.), and rigid ryegrass (Lolium rigidum Gaudin). We identified methyl cinnamate and methyl anisate as potential phytotoxins in the extracts, but we used pure commercial molecules to conduct bioassays. Methyl cinnamate showed higher phytotoxicity than methyl anisate and was selected for further bioassays. Methyl cinnamate reduced guaiacol peroxidase activity by 57% and 85% in L. rigidum and lettuce, respectively, and α-amylase by 6% in L. rigidum. This compound also inhibited early stem and radicle growth of dicotyledonous lettuce (60% and 89%, respectively) and monocotyledonous L. rigidum (76% and 87%, respectively), both species having small seeds. However, wheat with a larger seed size was not affected by the phytotoxin. The results obtained indicate a potential bioherbicidal effect for methyl cinnamate, and its application might be useful in wheat crops infested by L. rigidum. We suggest that collecting A. dealbata flowers would prevent Acacia seed formation and thus play a role in invasive pest management, as well as serving as a source of potential herbicides to other species.

“…Essential oil of L. origanoides Kunth, rich in carvacrol and p-cymene, was also efficient at controlling Aedes aegypt Linn, Tetranychus urticae Koch. and Cerathapis lataneae Boisd (Mar et al, 2018). Terpenes, the predominant compounds in Lippia essential oils, encompass a series of substances whose defensive properties in plants are well-known.…”

Lippia is one of the main genera in the family Verbenaceae, with 200 species described. Despite its richness in bioactive molecules, with several scientifically proven applications, there is little information on the insecticidal potential of its species. This study aimed to assess the insecticidal potential of essential oils from the species Lippia thymoides (Martius & Schauer); Lippia lasiocalycina (Schauer) and Lippia insignis (Moldenk) against Nasutitermes corniger (Motschulsky) (Isoptera-Termitidae). Insecticidal activity was evaluated by exposure to a contaminated surface, whereby plastic pots were lined with filter paper and imbibed in 1.5 ml of solution containing essential oils (10 µl/ml), with 10 N. corniger specimens per pot. The mortality count was performed at 24 and 48 h. The LC50 was determined by diluting the essential oils to concentrations of 0, 0.625, 1.25, 2.5, 5.0 and 10 µl/ml, which were chemically analyzed by GC-FID and GC-MS. The data indicated high toxicity for the essential oils for the Lippia species tested. The lowest LC50 (0.46 µl/ml) was recorded for L. lasiocalycina. The most common constituents were β-myrcene and (E)-ocimenone in essential oil of L. lasiocalycina, β-myrcene and limonene for L. insignis, and (E)-caryophyllene and caryophyllene oxide for L. thymoides. The results demonstrate the viability of developing biopesticides for N. corniger control.

“…In this context, the essential oils produced by plants may be an alternative to synthetic insecticides. Many studies have been developed in this area 18–24 and the discovery of new sources of essential oil with larvicidal activity is becoming important due to the low yield of this secondary metabolite that is produced by the plants.…”

BACKGROUNDEugenia calycina is an endemic species in the Brazilian savannah (the Cerrado) and it is threatened with extinction. Several species of Eugenia are used as insecticides or insect repellents. No data are available on the larvicidal activity of E. calycina. The chemical composition of the essential oil (EO) from leaves of Eugenia calycina was analyzed by gas chromatography coupled to mass spectrometry (GC–MS) and the larvicidal activity against Aedes aegypti larvae in the third stage of development was studied.RESULTSOxygenated and non‐oxygenated sesquiterpenes were identified, and the main compounds were bicyclogermacrene, spathulenol, and β‐caryophyllene. The EO was fractionated in a chromatographic column and three compounds were isolated and identified: spathulenol, aromadendrane‐4β,10α‐diol, and 1β‐11‐dihydroxy‐5‐eudesmene. It is the first time that the last two compounds have been identified in E. calycina. The exposure times in the larvicidal test were 24 h and 48 h and the LC50 values obtained were 199.3 and 166.4 μg mL−1. The cytotoxicity of the EO in mammalian cells (HeLa and Vero) was evaluated for 24 and 48 h of incubation. The cytotoxic concentrations of the EO for HeLa and Vero cells (266.8 ± 46.5 and 312.1 ± 42.5 μg mL−1, respectively) in 48 h of exposure were higher than the LC50, showing low cytotoxicity at the concentration exhibiting larvicidal activity, resulting in a positive selectivity index.CONCLUSIONThese results indicate that the EO of E. calycina showed high activity against the A. aegypti larvae but lower cytotoxicity to mammalian cells. The leaves of E. calycina are therefore a very promising source of natural larvicidal products. © 2020 Society of Chemical Industry
