Aims: To determine the phytochemical composition and antibacterial activity of Solanum incanum fruits against Ralstonia solanacearum. Study Design: Experimental design involving completely randomized design Place and Duration of Study: The study was conducted at department of Chemistry and Biochemistry, School of Sciences and Aerospace studies, Moi University, Kenya, between January and June 2021. Methodology: Extraction was done by maceration using ethanol as the extracting solvent. Phytochemical screening was done following standard procedures. Total Phenolic Content (TPC) and Total Flavonoid Content (TFC) were determined using the Folin–Ciocalteu colorimetric method and aluminum chloride colorimetric assay respectively. The extract was further analyzed using Gas Chromatography Mass spectroscopy (GC-MS) and Fourier transformed Infrared (FT-IR). In vitro antibacterial activity was determined using disc diffusion method while in vivo studies was done under greenhouse conditions. Results: Phytochemical analysis showed presence of alkaloids, glycosides, steroids, tannins, flavonoids, phenols, saponins and terpenoids. The TPC and TFC were found to be 84.997 ± 0.2 mg GAE/g and 20.535 ± 0.2 mg/g QE of dried sample respectively. GC-MS analysis revealed the presence of 15 compounds, (9E)-1-Methoxy-9-Octadecene (26.85%), 9-Octadecenamide (Z) (21.43%), E-15-Heptadecenal (7.28%), E-14-Hexadecenal (6.28%), 2,4-Di-tert-butylphenol (4.96%) among others. FT-IR analysis revealed presence of OH, C-H, N-H, CO functional groups at wavenumbers 3348 cm-1, 2931 cm-1, 1589 cm-1, and 1218 cm-1 respectively. The antibacterial activity for in vitro studies at concentrations 0.01, 0.05, 0.10, and 0.15 g/10 mL, the diameters of zone of inhibition were 20.75 ± 1.3, 25.75 ± 0.5, 27.25 ± 0.5, and 30.75 ± 0.5 mm respectively. This was comparable (P= .02) to that of ampicillin (positive control) which had zones of inhibition of 26.75 ± 0.5, 28.75 ± 0.5, 31.75 ± 0.4, and 35.00 ± 0.0 mm at the concentrations respectively. For the in vivo studies the plant extract and ampicillin delayed the development of the disease by eight and ten days post-inoculation respectively while symptoms of bacterial wilt for water treatment (negative control) were observed four days post-inoculation. Conclusion: The plant extract had remarkable antibacterial activity and can be used to make viable formulations to control the devastating bacterial wilt disease.

Senecio coincyi (Asteraceae) is a threatened endemic plant of central western Spain. The reproductive biology of this species in relation to the characteristics of its habitats and the possible strategies for its conservation, were studied. The area of occupancy, habitat types and size of 13 known subpopulations of S. coincyi was evaluated. Germination tests were carried out to assess the effect of temperature and light regimes, and the possible intraspecific variation on the cypsela germination. Cypselas reached very high germination percentages (90-100%) from 15ºC to 30ºC. However, the germination decreased (by about 19%) at 10ºC. The light conditions assayed did not significantly affect cypsela germination. In conclusion, S. coincyi showed high sexual reproduction ability, and therefore its conservation problems are not due to agents related to its reproductive biology, but to others, such as the alteration of its habitat caused by the presence of livestock

Senecio plants (Asteraceae) have been used to treat a wide range of ailments in traditional medicine. Current work has unveiled the identification of EO metabolites of collected S. glaucus from Egypt's Nile delta using GC‐MS and GC‐FID. Additionally, the antimicrobial activity has been investigated. Then, radical scavenging activity was evaluated using DPPH, ABTS, and metal chelating techniques. Also, the molecular docking studies were performed for the main compounds. Fifty components were identified within 98.80% of the total mass. Sesquiterpenes and monoterpenes constitute the main components. Dehyrofukinone (27.15%), 4,5‐di‐epi‐aristolochene (10.27%), and p‐cymene (4.77%) represented the most predominant constituents. The oil has showed remarkable antifungal activity against C. glabrata and C. albicans within the MIC and MFC values of 3.13 and 1.5 µg/ml‐1 and 12.5 and 6.3 µg/ml‐1, respectively. Also, this oil inhibited the growth of the tested bacteria with MIC ranging from 12.50‐100 µg/ml‐1. In comparison to ascorbic acid and Trolox, the EO had substantial scavenging activity of DPPH and ABTS radicals with IC50 values of 313.17, 493.83, and 47. µg/mL. Phytol revealed the best binding affinities toward the active sites of Gyrase B, α‐sterol demethylase, and tyrosine kinase Hck with ΔG = ‐7.42, ‐7.78, and ‐7.44 kcal/mol, respectively.
