Purpose: To investigate the insecticidal activity of the essential oil of Cinnamomum cassis and its main constituent compound, trans-cinnamaldehyde, against the booklice, Liposcelis bostrychophila. Methods: Steam distillation of C. cassis twigs was carried out using a Clavenger apparatus in order to obtain the volatile oils. Gas chromatography/mass spectrometric (GC/MS) analyses (HP-5MS column)...

Echinophora Platyloba D.C as a medicinal plant is used for preservation of foods and treatment of many diseases in different regions of Iran. The present study was undertaken to determine the chemical composition and investigation of the antibacterial effects of essential oil as well as methanol extract from aerial part of Echinophora Platyloba D.C against S. aure...

BACKGROUND The leaves of Ocimum basilicum L. (basil) are used in traditional cuisine as spices; its essential oil has found a wide application in perfumery, dental products as well as antifungal agents. AIM To assess the chemical composition as well as the in vitro antifungal activity of O. basilicum L. essential oil against Aspergillus flavus fungal growth and aflatoxin B1 production. MATE...

Epipremnum aureum is an important foliage plant in the Araceae family. In this study, we have sequenced the complete chloroplast genome of E. aureum by using Illumina Hiseq sequencing platforms. This genome is a double-stranded circular DNA sequence of 164,831 bp that contains 35.8% GC. The two inverted repeats (IRa and IRb; 26,606 bp) are spaced by a small single-copy region (22,868 bp) and a ...

In the present study, phytochemical constituents and in vitro antioxidative potential of different explants of E. aureum were evaluated. Methanol was used as solvent for extraction of E. aureum three explants (leaf, root and stem). Phytochemical screening was done by performing different chemical tests and presence of carbohydrate, protein, steroid, glycosides, alkaloids, saponins and amino aci...

The aim of the present study was to evaluate the chemical composition of essential oil isolated from the rhizomes of Kaempferia galanga L. The essential oil was isolated from the dried rhizomes of Kaempferia galanga L. by steam distillation method and analyzed by gas chromatography-mass spectrometry (GC-MS) technique. Total fifty constituents were identified from rhizome oil constituting 97.19%...

b a ckground: application of plant derivatives have been suggested as alternative sources for mosquito control. m ethods: the root essential oil and methanol extract of c ionura erecta (l.) griseb was tested under laboratory conditions for larvicidal and skin repelleny activities against anopheles stephensi . the chemical compositions of essential oils were analyzed using gas chromatography- ma...

The essential oil of Illicium simonsii fruit was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 40 components of the essential oil were identified. The principal compounds in I. simonsii fruit essential oil were β-caryophyllene (10.30%), δ-cadinene (9.52%), methyl eugenol (8.94), β-elemene (5.84%), and α-amorphene (5.20%). The essential oi...
