“…[15][16][17][18][19] In addition, rocket seeds possess a significant free radical scavenging capacity and exert a protective effect against HgCl 2 mediated renal toxicity. 2 Plant solvent extracts may exhibit antimicrobial, [20][21][22] antiinflammatory, 23 fungicidal 24,25 and insecticidal 26 27,28 substituting thereby the synthetic antioxidants restricted in many countries regarding their potential health related issues. 29 Extracting bioactive compounds from rocket leaves and seeds using solvents demonstrated the promising antimicrobial and antioxidant effects of these extracts.…”

Background and aim: Eruca sativa or most commonly known as rocket is a worldwide herbaceous plant usually used for salad preparations due to its astringent properties. The health benefits of its leaves and seeds were widely investigated, however no study has been conducted on its flowers demonstrating these benefits. The aim of this work is to investigate the phytochemical properties of solvent extract from rocket flowers. Method: Rocket flowers were collected at their blooming day and solvent extracts were prepared meaning hydrodistillation. Non-polar compounds were extracted using hexane and the efficiency of the obtained extract was evaluated using antibacterial and antioxidant activities. The antibacterial activities were tested against 11 pathogenic strains, whereas the antioxidant activities were tested through DPPH free radical scavenging activity, total antioxidant capacity and β-carotene bleaching test. Results: The antibacterial activities showed good growth inhibition compared to positive controls. The diameter of the inhibition zones reached a maximum of 16.7 ± 0.1 mm when tested against Salmonella typhimurium using 14 mg extract. The results obtained for the antioxidant activities showed more than 90% DPPH free radical inhibition, 315 µg AAE/ml for 71 mg/ml extract and more than 70% inhibition using β-carotene bleaching assay. Conclusion: The obtained phytochemical properties demonstrated the health benefit features of rocket flowers and their potential uses as feedstock of bioactive molecules.

“…These findings are in agreement with the earlier reports of Jeyasankar et al [16] . Several authors have reported that plant extracts possess similar type of antifeedant activity against lepidopteran pests [17][18][19][20] .…”

“…Also, sugars and amino acids could interfere with the perception of feeding stimulant receptors, while others may cause erratic bursts of electrical impulses in the nervous system resulting in feeding deterrence. (Jeyarajan et al, 1990;Jeyasankar et al, 2012;Jeyasankar et al, 2014) The main FA components represented as OL (C18) and LAME (C19) of the crude extract had a significant very low antifeedant effect only in high concentrations and particularly seemed to be attractive in very low concentrations. This findings were agree with (Ganesan et al, 2006) observations that Longer-chain-length FAs (C12-C18) were attractive at lower levels but repellent at higher levels for Aedes aegypti L. oviposition.…”

Toxicity and antifeedant effect of hexane apricot kernel extract (HEAK) and its gas chromatography-mass spectroscopy (GC-MS) identified fatty acid (FA) components palmitic acid (PA), Oleic acid (OL) and FA derivatives (Linoleic acid methyl ester (LAME)) were assessed against 2 nd and 4 th instar larvae of Spodoptera littoralis under laboratory conditions. Methoxyfenozide (Runner 24% SC ® ) was used as reference insecticide to (HEAK) and its components. The results were statistically analyzed by probit analysis to calculate (LC 50 ) of mortality and the concentrations caused 50% of antifeedant index (AI 50 ) after 24, 48 and 72 hrs of exposure. The results of toxic and antifeedant effects showed the definite prevalence of HEAK versus its FA components against the two instar larvae of S. littoralis throughout 72 hrs of exposure. However the toxic initiation of the extract and its components paced methoxyfenozide by the first 24 hrs of exposure, methoxyfenozide still owned a superior toxicity and antifeedant response on the treated larvae. This work has been associated with some physiological tests including haemocytes count and corpora allata (CA) activity.
