“…In the Fiji Islands, the sap of C. variegatum stem is used to treat sores. In China, a leaf decoction is massaged to treat edema and drunk for its anti-inflammatory properties [ 99 ]. In Papua New Guinea, C. variegatum roots are massaged to treat dislocated joints [ 100 ].…”

“…Besides some poor-quality studies, no work has focused on studying the anti-inflammatory properties of C. variegatum . However, flavonoids present in C. variegatum such as apigenin, rutin, orientin, vitexin, and isovitexin have been shown to possess anti-inflammatory effects [ 99 ]. It is noteworthy that the sap of C. variegatum leaf can induce contact dermatitis after long term exposure [ 101 ].…”

Background Traditional Polynesian medicine for children has been poorly documented, and few data are available on their efficacy and safety. In this context, the aim of this study was to identify traditional practices used for treating children and then assess the efficacy and safety of the most cited remedies by reviewing the literature. Methods In 2022, a semi-structured survey was carried out on five islands from the Society archipelago (Bora Bora, Huahine, Moorea, Raiatea, and Tahiti). A total of 86 participants were interviewed including 19 experts in herbalism. A thorough literature review was performed on the most cited plant species to gather the relevant ethnobotanical, pharmacological, and clinical data of each remedy. Results Participants mentioned using 469 remedies to treat 69 health disorders. The most represented health categories were digestive system, skin disorders, infectious diseases, and respiratory system. A total of 67 plant species (representing 731 use-reports) were mentioned and Annona muricata, Gardenia taitensis, and Hibiscus rosa-sinensis were the main plants reported. Regarding the safety of cited remedies, one plant (Microsorum grossum) showed high risk of toxicity, and its use should be avoided in infants and children. Conclusion Our survey confirms the importance of traditional medical practices for children in the Society Islands. A lack of data in children for most cited remedies demonstrate the need for more pharmacological and toxicological research on Polynesian medicinal plants. Finally, the potential risk of toxicity for some cited plant species reported calls for a better information of traditional medicine users and healers.

“…The mortalities observed with the extracts of C. variegatum and R. graveolens prepared by infusion and C. guianensis by decoction, although higher than the other treatments and the control, are still not equivalent to treatments with other botanical insecticides, chemical, and biological insecticides; part of this difference may be related to the size of the plant leaf, or to the method of extracting the metabolite from the plant, where the solvent used, water, was not able to extract the insecticide compounds, mainly due to its polarity, some chemical compounds are more effective when applied by direct contact at the insect stage, while others produce toxicity through ingestion of these substances (Gosselin 1976). In addition, the existing natural barrier in the cuticle of the insect stage evaluated in the tests can help to prevent/impede the absorption of toxic products and reduce the insecticidal effect ( 2017), although the observed action on P. xylostella may also be the result of the synergistic action of the extracted constituents (Njoya et al 2021). In the case of Taraxerol, the mode of action of the substance in insects has not yet been described, requiring more speci c studies.…”

Diamondback moth, Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae), is a vegetable pest of the genus Brassica worldwide. The development of new, safer bio insecticides with less negative impacts on human health, ora, fauna, and speci c to the target is needed to combat this pest, particularly in smallscale organic agriculture. In this sense, the e ciency of 7 plant species in the form of aqueous botanical extracts was evaluated regarding the bio insecticide effect, using three extraction methods (orbital agitation, decoction, and infusion). There was a difference between the treatments, highlighting the decoction of Couroupita guianensis, which presented the highest e ciency (39%) for second-instar larvae of P. xylostella, followed by infusions of Codiaeum variegatum and Ruta graveolens, both with a 29% e ciency rate. The 3 extraction methods were statistically different, with decoction and orbital agitation presenting the best results.

“…Activity DPPH antioxidant assay is based on the ability of 2,2diphenyl-1-picrylhydrazyl (DPPH), a stable free radical, which accept an electron or hydrogen atom and decolorize in the presence of antioxidants [30]. DPPH, a stable free radical was scavenged by the aqueous extract of the fruit of Phoenix dactylifera in a dose dependent manner.…”

Aims: Phoenix dactylifera fruit, grown majorly in northern part of Nigeria is acclaimed to possess numerous nutritional and medicinal properties. The study was carried out to investigate the nutritional/chemical constituents and the free radical scavenging potentials of the aqueous extract of Phoenix dactylifera fruit. Methods: The aqueous extract of the fruit was subjected to standard analytical test to assay for the amino acids, phytochemicals and free radical scavenging potentials: Phytochemicals and amino acids screening was carried out via High Performance Liquid Chromatography and Gas Chromatography Mass Spectrometry analyses. The antioxidant effects of the extract on free radicals were determined on radicals 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) , 2, 2-diphenyl-1-picrylhydrazyl , Nitric oxide and Hydroxyl radical. Results: Results revealed the presence of seven secondary metabolites with a high steroid and flavonoid content and low Coumarins, Glycosides, Alkaloids, Saponin, and Terpenoid concentration. The HPLC analysis of the phytochemical showed that it contained fifteen phytocompounds, seventeen amino acids while GCMS analysis reveals eleven fatty acids. For the free radical scavenging activity, it was able to inhibit ABTS, DPPH, NO, and OH-, in a concentration dependent manner. Conclusions: The results indicate that the fruit possess good nutritional properties and abundant secondary plant metabolites constituents and this might provide evidence which corroborates with the free radical scavenging potentials of the fruit.
