Balanites aegyptiaca is a medicinal plant that serves as a source of phytochemicals with antimicrobial effect. This work aimed at screening for phytochemical constituents and investigating the antifungal activity of B. aegyptiaca seed and callus extract against Candida albicans. Callus induction from B. aegyptiaca seed kernel explant was done on MS basal nutrient medium supplemented with 0.5 BAP + 1.0 2, 4-D + 1.0 NAA.  Cultures were kept under a controlled temperature and light conditions for five weeks. Plant materials were extracted using solvent extraction. 50 ml of the solvents: methanol and n-hexane were mixed with five grams (5 g) each of the grounded plant materials (1:10) w/v. Determination of antimicrobial activity was done using disc diffusion assay. Diffusion discs of approximately 6 mm diameter were prepared from Whatman No. 1 filter paper, then sterilized and autoclaved before drying in an oven. 10 µl of 50 and 100 mg/ml concentration of each crude extracts was impregnated on separate sterile disc using sterile micropipette tips. The diameter of zone of inhibition at 100 and 50 mg/ml showed the methanolic extract of callus had the highest zone of inhibition with 17 ± 0.69 mm and 11 ± 0.94 mm. The lowest diameter of zone inhibition of callus extracts was recorded by n-hexane extract at 100 (15 ± 0.46 mm) and 50 mg/ml (09 ± 0.57 mm) respectively. Also, the MIC ranged between 6.25 and 12.50 mg/ml and MFC recorded value of 12.50 mg/ml. Seed methanolic extract had the highest zones of inhibition of 15 ± 0.34 mm and 10 ± 0.62 mm at 100 and 50 mg/ml respectively, while the lowest value (12 ± 0.51 mm and 09 ± 0.23) was recorded in n-hexane at 100 and 50 mg/ml. From the results, both the MIC and MFC of seed extracts ranged from 12.50 to 25.00 mg/ml. Callus extracts showed stronger antifungal activities compared to the seed extracts. Therefore, from the result, Callus extract from B. aegyptiaca can serve as a good source of therapeutic compounds for fungal related disease.

<em>Neem, mahogany, and surian seeds contain secondary metabolites that can be used as biopesticides. This study aimed to determine the effectiveness of neem, mahogany, and surian seed extracts to the larvae of the </em>Tenebrio molitor<em> L. (Tenebrionidae: Coleoptera) </em><em>at laboratory scale. The stages of the research were the preparation of seed extracts, phytochemical analysis of the extracts, and efficacy of extracts against </em>T. molitor<em> larvae. Dried seeds of neem, sur</em><em>ian, and mahogany (water content &lt; 10%) were ground (100 mesh) and macerated with 95% ethanol solvent for seven hours at 70 <sup>o</sup>C. The alkaloids, flavonoids, tannins, saponins, and steroids/the triterpenoid were then analyzed. The effectiveness of the extracts was  tested</em><em>against the 3<sup>rd</sup> larva of </em>T. molinor<em>. The experiment</em><em> designed in Randomize block design, three replications, each with ten larvae. The first factor was seed extracts (neem, surian, and mahogany), while the second factor was five levels of extract concentration (</em><em>0 mg;l<sup>-1</sup>, 9 mg.l<sup>-1</sup>, 15 mg.l<sup>-1</sup>, 30 mg.l<sup>-1</sup> and 45 mg.l<sup>-1</sup>). Phytochemical analysis showed that mahogany seeds contained alkaloids and triterpenoids. Meanwhile, surian seeds contained tannin, alkaloid, steroid/triterpenoid, but neem seeds contained saponin and alkaloids. The mahogany, surian, and neem seed  extracts were effective in causing significant mortality to </em>T. molitor<em> larvae. Ethanol extract of neem seeds was more toxic to larvae (LC<sub>50</sub> = 0.72 mg.l<sup>-1</sup>), compared to mahogany (LC<sub>50</sub> = 5.2 mg.l<sup>-1</sup>) and sur</em><em>ian (LC<sub>50</sub> = 7.02 mg.l<sup>-1</sup>). Mimba seed extract is more prospective to be developed as a botanical insecticide.</em>

In recent years, green nanotechnology-based approaches using plant materials have been accepted as an environmentally friendly and cost-effective approach with various biomedical applications. In the current study, AgNPs were synthesized using the seed extract of the Eugenia uniflora L. (E.uniflora). Characterization was done using UV-Visible spectroscopy, X-ray diffraction (XRD), scanning electronic microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) analyses. The formation of AgNPs has confirmed through UV-Visible spectroscopy (at 466 nm) by the change of color owing to surface Plasmon resonance. Based on the XRD pattern, the crystalline property of AgNPs was established. The functional group existing in seed of E.uniflora extract accountable for the reduction of Ag+ ion and the stabilization of AgNPs was investigated. The morphological structures and elemental composition was determined by SEM and EDX analysis. With the growing application of AgNPs in biomedical perspectives, the biosynthesized AgNPs were evaluated for their antibacterial and along with their antidiabetic potential. The results showed that AgNPs are extremely effective with potent antidiabetic potential at a very low concentration. It also exhibited potential antibacterial activity against the three tested human pathogenic bacteria. Overall, the results highlight the effectiveness and potential applications of AgNPs in biomedical fields such as in the treatment of acute illnesses as well as in drug formulation for treating various diseases such as cancer and diabetes. It could be concluded that E. uniflora seed extract AgNPs can be used efficiently for in vitro evaluation of their antibacterial and antidiabetic effects with potent biomedical applications.

ABSTRACT The leafminer [Liriomyza sativae (Diptera: Agromyzidae)] is one of the main pests of melon crop (Cucumis melo) in the states of Rio Grande do Norte and Ceará. Thus, adopting strategies to control this destructive insect is essential. The aim of this study was to evaluate the effect of aqueous neem seed extract, applied to soil via irrigation, on leafminer larvae, in the melon crop. An experiment was conducted in greenhouse, in completely randomized design, consisting of five treatments (four doses of aqueous neem seed extract: 1; 3; 5 and 10 g/100 mL) and the control consisting only of distilled water and 10 replicates (melon plants). The treatments were applied in a single dose, via soil irrigation. In the first stage of the evaluation, 24 hours after application, the number of dead larvae per plant was counted. In the second step, pupal mortality was recorded. The total mortality was also calculated considering the number of larvae and the number of emerged adults. We verified that, increasing the concentration of aqueous neem seed extract, an increase in the larval and pupal mortality of the leafminer in melon crop was noticed. The concentration 10 g/100 mL presented the best results, resulting in 36.4% of larval mortality, 96.5% of pupal mortality and 96.8% of total mortality.
