“…The ionization energy of the mass spectrometer was 70 eV and the split ratio 1:30; all other conditions were identical to those mentioned for GLC. Compounds were identifi ed by comparing their spectral data and retention indices with Wiley Registry of Mass Spectral Data 8 th edition, NIST Mass Spectral Library (December 2005), and the literature (Adams, 2007;El-Shazly and Hussein, 2004). The identifi ed constituents are listed in the order of their elution in Table I.…”

The volatile secondary metabolites of essential oils from fruit peel and leaves of variegated pink-fl eshed lemon (Citrus x limon) were investigated using GLC and GLC-MS (gas-liquid chromatography-mass spectroscopy). Altogether 141 compounds were identifi ed and quantifi ed, accounting for 99.59% and 96.33% of the total hydrodistilled peel and leaf oil, respectively. Limonene occurred in higher amounts in fruit peel (52.73%) than in leaf oil (29.13%). Neral (12.72%), neryl acetate (8.53%), ρ-menth-1-en-7-al (4.63%), β-pinene (6.35%), and nerol (4.42%) were the most abundant constituents in leaf oil, whereas γ-terpinene (9.88%), β-pinene (7.67%), geranial (4.44%), and neral (3.64%) dominated in the fruit peel oil. The antioxidant, anti-infl ammatory, antitrypanosomal, and antimicrobial activities of the fruit peel essential oil were evaluated. The oil had a low antioxidant activity with an IC 50 value of (26.66 ± 2.07) mg/ml as compared to the effi cient antioxidant ascorbic acid [IC 50 (16.32 ± 0.16) μg/ml]. The oil moderately inhibited soybean 5-lipoxygenase (5-LOX) with an IC 50 value of (32.05 ± 3.91) μg/ml and had moderate antitrypanosomal activity [IC 50 (60.90 ± 0.91) μg/ml]. In addition, moderate antimicrobial activities were detected against Gram-positive bacteria (Bacillus subtilis, Staphylococcus capitis, Micrococcus luteus), one Gram-negative bacterium (Pseudomonas fl uorescens), and yeasts (Saccharomyces cerevisiae, Candida parapsilosis).

Abstract:The sweet potato whitefly, Bemisia tabaci (Genn.) (Biotype A: Hem.: Aleyrodidae) is one of the most important pests in Iran. The development of alternative methods that are not chemical applications, is necessary in pest management for the sake of human health and for the safety of the environment. In this research project, the effect of four herbal compounds Fumaria parviflora Lam. The results showed significant differences between herbal compounds and insecticides on: egg longevity (F 6, 39 = 2.96, p < 0.05), pupa longevity (F 6, 37 = 4.49, p < 0.01) and adult longevity (F 6, 31 = 4.47, p < 0.01); egg mortality (F 6, 39 = 6.71, p < 0.001), total egg mortality (F 6, 39 = 6.71, p < 0.001), sex ratio (female) (F 6, 30 = 3.49, p < 0.01), oviposition period (F 6,31 = 7.50, p < 0.001) and total fecundity/female (F 6, 31 = 8.23, p < 0.001).These results indicated that a fumitory extract and pymetrozin had the best effect on longevity and mortality, respectively. According to the results, the fumitory had a noticeable effect on the different life stages of the sweet potato whitefly.

“…Identifi cation of the compounds was based on their mass spectra, retention indices, and comparison with published data (Adams, 2007;El-Shazly and Hussein, 2004;El-Shazly et al, 2002. On the other hand, we could not fi nd any traces of (Z)-3-hexen-1-ol, β-caryophyllene, and 6-demethoxy-ageratochrome which have been reported as major compounds in the essential oil of leaves from G. parvifl ora growing in Colombia (Pino et al, 2010).…”

The phytochemical investigation of an aqueous ethanolic extract of Galinsoga parviflora Cav. (Asteraceae) resulted in the isolation and identification of eleven compounds namely: triacontanol, phytol, β-sitosterol, stigmasterol, 7-hydroxy-β-sitosterol, 7-hydroxystigmasterol, β-sitosterol-3-O-β-D-glucoside, 3,4-dimethoxycinnamic acid, protocatechuic acid, fumaric acid, and uracil. Furthermore, 48 volatile constituents were identified in the hydrodistilled oil of the aerial parts. The ethanolic extract at a content of 400 mg/kg body weight (BW) exerted 87% reduction in the alanine aminotransferase enzyme level in cirrhotic rats compared with the standard silymarin (150 mg/kg BW) and also exerted a reduction in the blood glucose level equivalent to that of glibenclamide (5 mg/kg BW) in diabetic rats. The ethanolic extract, light petroleum and ethyl acetate fractions exhibited substantial antimicrobial activity against Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, Aspergillus niger, and Candida albicans. The ethyl acetate fraction showed strong antioxidant activity at a concentration of 150 mg/mL as compared with 0.1 M ascorbic acid. The cytotoxic effect against the MCF-7 cell line was found to be weak
