“…Comparing the present data ( Table 1 ) with those previously reported in literature, the studied essential oils displayed different chemical profiles, although monoterpene hydrocarbons have been reported as the main constituents of the essential oils of several species of the genus Senecio [ 25 , 27 , 28 , 30 , 31 ], which are similar to the South Africa species. However, some species of this genus are characterized by high percentage of oxygenated compounds and mainly furanoeremophilan, as was found in Senecio chrysanthemoides , Senecio vernalis and Senecio aegyptius var.…”

The essential oils of the flowers, leaves and stems of Senecio polyanthemoides Sch. Bip. Samples collected from two different localities within the city of uMhlathuze, KwaZulu-Natal Province (South Africa) were isolated by hydrodistillation and analyzed using GC and GC/MS. Twenty-six constituents were identified, representing an average of 86.0 - 99.6% of the total oil composition. The chemical profile reveals the dominance of monoterpenoid compounds, although some quantitative variance was noticed. The main constituents of the oils were limonene (3.1 – 43.0%), p-cymene (4.9-36.3%), β-selinene (1.3-32.7%), α-pinene (1.8-21.4%), β-pinene (7.6-16.5%) and 1,8-cineole (9.3-11.4%), caryophyllene oxide (4.1-13.4%) and humulene epoxide II (8.6-10.3%).

“…The temperature of the EI 70 eV source was 200 °C with full scan (25-450 m/z), scan time 0.3 s. The essential oil components were identified by comparing the mass spectra of the analytes with those of authentic standards from the mass spectra of Wiley 6.0 and Mass Spectra Library (NIST 98), and with corresponding data of components from reference oils analyzed in our laboratory. a Retention as determined on the OV-101 column using the homologous series of n-alkanes (C [8][9][10][11][12][13][14][15][16][17][18][19][20] ) t = traces.…”

An essential oil from Senecio atacamensis Phil. (Asteraceae) was obtained by hydrodistillation of its aerial parts (leaves and stems) and its composition was determined by GC and GC/MS analysis. The identification by GC of the essential oil components, in both leaves and stems respectively, showed α-terpinene (36.05% and 20.57%); α-phellandrene (27.79% and 25.37%), and p-cymene (11.85% and 22.55%) as the most abundant monoterpenes. Furthermore, the oil was tested for its antimicrobial activity using paper disc diffusion and the dilution broth method, exhibiting moderate inhibition of human pathogenic bacteria.

“…[11,19,20] Monoterpenes and sesquiterpenes were reported to be the main components of EOs derived from Senecio species. [21][22][23] EOs from different Senecio species have been reported to have significant biological functions, such as antibacterial, [24] antimicrobial, [25] and cytotoxic effects, [26] respectively. In addition to having antibacterial effects, Senecio EOs also possess antifungal activity against Candida albicans, [27] Fusarium oxysporum, [28] and Trichophyton tonsurans.…”

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.
