The volatile oils from red and black rice bran were obtained by hydrodistillation using diethyl ester and the components of that oil were analyzed by capillary GC-MS. The volatile components of essential oil from red and black rice bran were analyzed by GC and GC-MS. One hundred twenty-nine (129) of volatile compounds were identified in red and black rice bran. Myristic acid, nonanal, (E)-beta-...

The hydro distilled essential oil of fresh leaves of Platycladusorientalis (L) Franco [Thujaorientalis] Family: cupressaceae was analysis by gas chromatography and gas chromatography/mass spectrometry.(GCMS). The oil yield is (1.25%) w/w. Thirty two compounds representing 96.62% of the total oil were identified. The main constituents are IR-αpinene (15.92%), α-caryophyllene (10.42%), trans-β oc...

The chemical compositions of essential oils obtained from Ocimum basilicum var. thyrsiflora (1.39 % dry weight) and Ocimum basilicum (0.61 %) were analyzed by GC–MS. Seventy-three constituents representing 99.64 % of the chromatographic peak area were obtained in the O. basilicum var. thyrsiflora oil, whereas 80 constituents representing 91.11 % observed in the essential oil of O. basilicum wer...

The lesser mealworm, Alphitobius diaperinus Panzer 1797 (Coleoptera: Tenebrionidae), is a cosmopolitan insect pest affecting poultry production. Due to its cryptic behavior, insecticide control is usually not efficient. Thus, sustainable and effective methods would have an enormous and positive impact in poultry production. The aim of this study was to confirm the identity of the male-produced ...

Tagetes is a genus of 56 species of annual and perennial mostly herbaceous plants in the sunflower family (Asteraceae or Compositae).In this research our goal was recognizing the main components of the plant to extract useful ones. Essential oils of the leaves, seeds and flowers of Tagets minuta L., growing wild in Iran, were extracted by hydrodistillation an...

The genus Hypericum is one of the most important medicinal plants that contain 17 species in Iran, three of them are endemics. This paper reports the essential oil composition of six Hypericum species from Iran. The essential oil analysis of a number of the studied plants has already been reported but their report from Iran may be valuable for scientists.  Samples collected between June and Aug...

In this study, the properties of nutritional, color and volatile organic compounds currant varieties (Ribes spp.) in Turkey were investigated. A total 125 different identified with GC-QTOF/MS. The levels protein, sugar fractions, dietary fibre, ascorbic acid minerals fruits found to be between varieties. Ascorbic content ranged from 169.33 725.52 mg/100 g dry weight. K, Ca Mg high amount all To...

The essential oil from the flowering aerial parts of Heracleum lanatum Michx. family Apiaceae was obtained by hydrodistillation and analysed by combination of GC (RI) and GC-MS. The chemical composition of the isolated oil is reported for the first time. Sixty five compounds were identified representing 96.95% of the total oil. The chemical composition of the isolated oil was characterised by a...
