“…Several bioactive compounds isolated from A. oleracea have anesthetic, anti-inflammatory, antioxidant, and diuretic activity (Freitas-Blanco et al 2016; Dallazen et al 2020; 2022; Rondanelli et al 2020). Its main bioactive compound, spilanthol, has antifungal, bacteriostatic, and insecticidal effects (Spinozzi et al 2022). This compound has already been reported to control insects of agricultural importance, such as Helicoverpa zea , Plutella xylostella , and Tuta absoluta , and insect vectors of human diseases, including Aedes aegypti , Anopheles spp.…”

Jambu plants (Acmella oleracea) exhibiting necrotic angular leaf spots were collected in Belém - Pará, Brazil. After previous analysis, the presence of nematodes fromAphelenchoidesgenus was observed. These nematodes were cultured onFusariumsp. and subsequently morphologically and molecularly characterized for species-level identification.Aphelenchoidessp. associated with jambu exhibited morphological and morphometric characteristics very similar to those of species within theA. besseyicomplex (A. besseyi,A. oryzaeandA. pseudobesseyi), but these characteristics were not sufficient to separate them into a unique species. The Bayesian inference analysis, utilizing the expansion segment of the large subunit (D2-D3 LSU) of nuclear ribosomal DNA, yielded results with a high posterior probability, indicating that theAphelenchoidessp. associated with jambu belongs to theA. pseudobesseyispecies. Under controlled conditions, the reproduction of the nematode in the leaf tissues (FR > 1) was observed, resulting in disease symptoms. The highest reproduction rate ofA. pseudobesseyi(FR = 2.6) was observed from inoculation with 100 nematodes per leaf. It is concluded thatA. pseudobesseyiis the etiological agent of jambu angular leaf spot. For future research, like evaluating the resistance of jambu to this nematode, it is recommended to inoculate a maximum of 100 nematodes per leaf.

Acmella oleracea, a leafy vegetable native to the Amazon region, has potential for the cosmetic, pharmaceutical and gastronomic industries. Hot environments and or low relative humidity accelerate losses of vigor and quality, making unfeasible to storage seeds of this plant. This makes necessary to develop new propagation and conservation techniques for A. oleracea. The objective was to evaluate the biometric characteristics, describe the stomata and to verify the presence or absence of epicuticular wax on the abaxial leaf epidermis of A. oleracea plantlet obtained from the conversion of synthetic seeds (SS) in vitro. The nodal segments of micropropagated plantlets, at different concentrations of 6-benzylaminopurine (BAP) (0.000; 0.025; 0.050; 0.100 and 0.200 mg l-1), were sectioned into explants of approximately 0.3 cm, encapsulated in alginate matrix to produce SS, inoculated in test tubes with Murashige & Skoog culture medium and kept in a growth room at a temperature of 25 ± 2 ºC and a photoperiod of 16 hours. The percentage of SS conversion, number of leaves and shoots, height and root dry mass were higher in the treatments with BAP. Shoot dry mass was 54.5% higher on plants originated from SS obtained with 0.100 mg l-1 of BAP than in the control. Anomocytic and ellipsoid-shaped stomata were well defined and epicuticular wax deposition was not observed on the abaxial epidermis of A. oleracea plantlets leaves. The stomata of A. oleracea and the absence of epicuticular wax on the leaf epidermis of this plant were similar between treatments.

We would like to submit a Letter detailing our recent findings on the pharmacological effect of a combination of Boswellia serrata and Acmella oleracea (code 9100135 dry extract 25% triterpenic acids for the Boswellia serrata and code 1136/45/A dry extract 3% alcylamides for the Acmella oleracea) extracts in a mouse model of spared nerve injury-induced neuropathic pain. The spared nerve injury was induced as previously described by our group and others (Boccella, Cristiano, et al., 2019). Our study aimed to assess the potential synergistic effects of these extracts at different dosages and evaluate their antiallodynic efficacy in a peripheral neuropathic pain model. Neuropathic pain is a debilitating condition resulting from damage or dysfunction of the nervous system (Guida et al., 2020). The tactile allodynia, defined as a painful sensation perceived following an innocuous stimulus, is the major symptom that limit the quality of life of patients suffering from neuropathic pain. Current pharmacological interventions often provide limited relief and are associated with undesirable side effects. Because of their analgesic qualities and excellent safety profiles, natural compounds have drawn interest as viable add on to pharmaceuticals for the treatment of neuropathic pain.For millennia, folk medicine has made use of the plant Boswellia serrata. Among consumers, it has grown in popularity as a treatment for a variety of chronic inflammatory disorders, including inflammatory bowel disease, asthma, arthritis, particularly osteoarthritis and pain.Boswellia serrata contains monoterpenes, diterpenes, triterpenes, tetracyclic triterpene acids, and pentacyclic triterpene acids, called boswellic acids (BAs) (Riva et al., 2017).Acmella oleracea (L.) is the most common cultured species of the Acmella genus belonging to the Asteraceae family. It is native to South
