A simple and rapid method is reported for the routine determination 1-phenylazo-2-naphthol (Sudan I) in chilli powder chilli-containing food products. The involved Soxtec extraction from products followed by high-pressure gel permeation chromatographic clean-up collecting appropriate fraction. Analysis of this fraction was HPLC with UV/VIS detection. limit detection 7 μg kg−1 quantification 13 kg−1. identity Sudan I established electrospray LC/MS MS/MS confirmation. From a small survey 30...
A wild strain of Agrobacterium rhizogenes was used to regenerate twelve in vitro plant lines from different hairy roots H. perforatum (St. John's Wort). The production the main bioactive constituents observed even though their yields varied lines. Two were selected for hyperoside (4.9-4.6 mg/gdw) while nine characterized by significant chlorogenic acid (ranged 0.47 1.09 mg/gdw). Furthermore, one out showed a 10-fold higher hypericin content (0.25 than that reported shoots literature....
Context: Hypericum perforatum L. (Guttiferae) contains many bioactive secondary metabolites including hypericins, hyperforins, and essential oil.Objective: The present study was conducted to determine the variation in composition of oil H. accessions from Turkey.Material methods: At full flowering, aerial parts 30 plants were collected 10 sites northern Turkey assayed for components by GC-FID GC-MS.Results: chemical analysis revealed that main constituents all analyzed samples hydrocarbon...
Abstract The flower and leaf oil of Hypericum triquetrifolium Turra (Guttiferae, Hypericoideae) from Calabria (Italy) were studied by GC GC–MS. major components identified in each n ‐nonane (8%, 15%), β ‐pinene 4%), α (13%, 10%), myrcene (16%, 5%), ‐caryophyllene (5%, 11%), germacrene‐D (10%, 13%), sabinene 3%) caryophyllene oxide 12%) the oils, respectively. aerial parts same plant also analysed SPME. SPME analysis showed higher yields undecane (14%, 10%) comparison with corresponding...
A series of task-specific ionic liquids (TSILs) based on glycerylimidazolium cations have been prepared by reaction 1-chloropropanediol, a compound obtainable from glycerol (a widely available and in-expensive waste product), with the appropriate base (1-H-imidazole, 1,2-dimethylimidazole 1-methyl-1-H-imidazole). The 3-(1H-imidazol-1-yl)propane-1,2-diol chloroalkanes, bromoalkanes alkyl mesylates gave corresponding salts which were characterized. possibility to use these ILs in palladium...
Essential oils (EOs) of Achillea millefolium, Myrtus communis, Rosmarinus officinalis, Helichrysum italicum, Foeniculum vulgare and Lavandula angustifolia were analysed with GC–FID GC–MS in order to define their aromatic profiles then toxicity repellent activity against Sitophilus zeamais Motsch. (Coleoptera Dryophthoridae) specific bioassays evaluated. Results from topical applications on insects showed that all EOs had variable significant insecticidal activity. Mortality rate never...
Three new flavonoids (1-3) and 11 known compounds (genistein, isoprunetin, wighteone, laburnetin, alpinumisoflavone, genistin, genistein 8-C-glucoside, apigenin, isokaempferide, licoflavone C, D-pinitol) were isolated from the aerial parts of Genista ephedroides. The structures established as hydroxyalpinumisoflavone (1) [4', 5-dihydroxy-2"-methyl-2"-hydroxymethylpyrano(5",6":6,7)isoflavone], ephedroidin (2) [4',5, 7-trihydroxy-8-(2-hydroxy-3-methyl-3-butenyl)flavone], genisteone (3)...
Abstract Smyrnium olusatrum L. is a biennal plant growing in western and southern Europe. Several phytochemical studies have identified flavonoids, phenolic acids sesquiterpene lactones as main constituents. In this work the root, stem leaf essential oils of (Umbelliferae) collected Urbino (Marche, Italy) were studied by GC GC‐MS. Myrcene (1, 13 14%), β ‐phellandrene (34, 17 9%), ‐caryophyllene 3 12%), furanodiene (19, 8 17%), curzerene (13, 6 germacrene B (7, 14 10%) germacrone (8, 7 8%)...
