eng Investigation of phenotypic and molecular diversity of Descurainia sophia (L.) Webb ex Prantl and Sisymbrium irio (L.)
Bagheri, Hedayat; Saki, Sahar; Jafari, Adel; Naderi, Raziye; Deljou, Ali
Descurainia sophia and Sisymbrium irio, both from Brassicaceae family have potential medicinal effects. Seeds are consumed widely across Iran in sweet drinks. To determine the morphological and molecular diversity, 55 genotypes from these two genera were studied. All 11 ISSR primers detected polymorphism and generated 274 polymorphic loci. The average values of Polymorphism Information Content (PIC), Marker Index (MI) and Resolving Power (Rp) for ISSR primers were 0.278, 6.899 and 11.57, respectively. The AMOVA analysis revealed a high genetic...

eng Chemical Composition of the Essential Oil from Aerial Parts of Stachys palustris L. (Lamiaceae) Growing Wild in Southern Italy
Senatore, Felice; Formisano, Carmen; Rigano, Daniela; Piozzi, Franco; Rosselli, Sergio
Croatica Chemica Acta Vol. 80, No. 1, 2007
The paper reports the composition of the essential oil from aerial parts of Stachys palustris L. (Lamiaceae) from Southern Italy. The essential oil was extracted by hydrodistillation from selected plants and its chemical composition was determined by the GC-MS system on two fused- silica capillary columns of different polarity. The mass fraction of oil was 0.21 % on a dry weight basis. Altogether, 92 compounds were identified accounting for 93.6 % of the total oil, which was characterized mainly by carbonylic compounds (25.4 %), fatty acid...

hrv Instrumentizacija u analitici održivoga razvoja - Plinska kromatografija - masena spektrometrija GC-MS
Žvorc, Dorotea; Purić-Hranjec, Marija Purić-Hranjec; Varga, Andrea Varga; Pintarić, Lana Pintarić
Potreba za jasnom identifikacijom komponenata u složenim biološkim i nebiološkim uzorcima dovela je do razvoja vezanih instrumentalnih tehnika, a jedna od takvih je široko i uspješno korištena plinska kromatografija s masenom spektrometrijom (engl. Gas Chromatography-Mass Spectrometry, GC-MS). GC-MS je analitička metoda koja objedinjuje plinsko-tekućinsku kromatografiju (odjeljuje pojedine komponente uzorka i kvantificira ih) i spektrometriju masa (identificira svaku od komponenata pojedinačno). Veza tih dviju tehnika međusobno pove...

eng PESTICIDE CONTAMINATION IN CAULIFLOWER AND RELATED HEALTH RISK ASSESSMENT IN GURUGRAM, INDIA
Rani, Jyoti; Chaudhary, Sudesh; Agarwal, Tripti
Imprudent use of pesticides in agriculture has resulted in increased concentrations of pesticides in food. Consumption of pesticide-contaminated vegetables can cause many chronic and acute health problems for consumers. Vegetables are an important part of the human diet as they are a source of vitamins and minerals. Cauliflower (Brassica oleracea var. botrytis) is a frequently consumed vegetable in India and has high nutritional value. In the present study, cauliflower was scanned for organochlorines, organophosphates, synthetic pyrethroids and...

eng Composition of Essential Oils in Needles and Barks of Turkish Red Pine (Pinus brutia Ten.) Infested by Marchalina hellenica Genn.
hrv Sastav eteričnih ulja u iglicama i kori turskoga crvenog bora (Pinus brutia Ten.) zaraženoga insektom Marchalina hellenica Genn.
Arslan, Mustafa Burak; Küçükaydin, Selçuk; Taş-Küçükaydin, Meltem; Duru, Mehmet Emin; Şahin, Halil Turgut
Drvna industrija Vol. 73, No. 2, 2022
The scale insect Marchalina hellenica Genn. plays a key role in pine honey production and is hosted mainly by Turkish red pine (Pinus brutia Ten.). The needles of Turkish red pine are rich in essential oils. Moreover, essential oils can affect the host selection of insects. The essential oils in the needles and barks of Marchalina hellenica-infested and non-infested Turkish red pine were obtained via water distillation and their composition was determined by GC-MS analyses. The composition of the essential oils was found to differ in the needle...

eng Effect of Harvest Time on Yield and Quality of Thymus vulgaris L. Essential Oil in Isfahan Province, Iran
Salehi, Saied; Golparvar, Ahmad Reza; Hadipanah, Amin
Thyme (Thymus vulgaris L.) is a perennial sub shrub belonging to family Lamiaceae. Thyme essential oils have been used for many thousands of years, especially in food preservation, pharmaceuticals, alternative medicine and natural therapies. In order to determine the effect of harvest time on quality and quantity of essential oil in thyme, this experiment was done in a randomized complete block design with three replications at research station of Islamic Azad University, Khorasgan (Isfahan) during 2010-2011. Plants were harvested in five stage...

eng Chemical composition and insecticidal activity of two eagle fern (Pteridium aquilinum) extracts on the poplar aphid Chaitophorus populialbae (Hemiptera-Aphididae)
ZAID, Ratiba; MOUHOUCHE, Fazia; CANELA-GARAYOA, Ramon; BENDDINE, Hichem; ORTEGA CHACÓN, Nancy Milena
Within the framework of the development of the Algerian flora, the seriousness of the damage caused by aphids of which the species Chaitophorus populialbae Boyer de Fonscolombe, infested the white poplar and the search for alternative solutions more respectful for the environment relying on the role of biopesticides of plant origin, we chose a plant Pteridium aquilinum Linné, belonging to the family Dennstaedtiaceae which presents various biological activities, in particular insecticide. This study is intended to improve our knowledge of th...

eng Free and Glycosidically Bound Volatiles of <i>Mentha citrata</i> Ehrh.
Mastelić, Josip; Miloš, Mladen; Kuštrak, Danica
Croatica Chemica Acta Vol. 73, No. 3, 2000
Free and glycosidically bound volatiles of surficial parts of <i>Mentha citrata</i> were investigated. Free volatile compounds were isolated from dried plant material by two methods: hydrodistillation and extraction with pentane used as control. Free volatile compounds as well as the aglycones obtained after enzymatic hydrolysis of gly-cosides were analyzed by gas chromatography-mass spectrometry (GC-MS). A significant difference in qualitative and quantitative composition of volatile compounds of the essential oil and pentane extract was found...

hrv Tehnologije koje se primjenjuju za terensku detekciju bojnih otrova: II. dio – Detektori nove generacije
eng Technologies Used for Field Detection of Chemical Warfare Agents: Part II – New Generation Detectors
Cetina, Ivana; Tušek, Dragutin; Ključarić, Valentina
Kemija u industriji Vol. 71, No. 9-10, 2022
Ubrzo nakon uvođenja komercijalnih automatskih detektora bojnih otrova, većinom temeljenih na spektrometriji ionske pokretljivosti, krajem 20. stoljeća razvijaju se terenski uređaji koji primjenjuju i druge tehnike kemijske detekcije (FTIR, Raman, GC-MS, površinski akustični val, fotoakustične, elektrokemijske, biosenzorske i ostale). Od navedenih tehnika, prijenosni GC-MS detektori omogućuju vrlo pouzdanu kvalitativnu i kvantitativnu kemijsku analizu, no problem predstavljaju visoka cijena tih uređaja, zahtjevnost u rukovanju s njima te komple...
