Insecticide and repellent activity of an acetone extract and oil from fresh leaves of Pelargonium x hortorum (cv. Orangesonne) were evaluated against the 2nd and 4th instar larvae of Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae). The oil showed medium toxicity against the 2nd instar and low toxicity against the 4th instar larvae, while the extract showed high significant toxicity at a...

The volatile components of the flower and fruit oils from Pittosporum tobira (Thunb.) Ait. grown in Iran, obtained through hydrodistillation, were analyzed by GC/MS. Sixteen compounds (representing 90.7% of the oil) and seventeen constituents (representing 89.9% of the oil) were identified in the flower and fruit oils, respectively. While the flower oil contained a-pinene (38.6%), n-nonane (11....

The antifungal properties of some commercial plant waters obtained as side products in producing distilled oils were investigated. Paper disc samples were impregnated with various plant waters and exposed to wood decay fungi for 3 months in Petri dishes. Ten types of plant water (Laurus nobilis, Calluna vulgaris, Lavandula stoechas, Thymus vulgaris, Myrtus communis, Eucalyptus globulus, Mentha ...

The roots of Chrysopogon zizanioides (L.) Roberty, belonging to the Poaceae family, are main source volatile that has substantial value in perfume, cosmetics, pharmaceutical and food industries. study C. volatiles, obtained from plant cultivated Tunisia, using GC GC/MS revealed more than 50 compounds were detected which 14 constituents identified representing 33.87% total. Oleic acid (17.09%) (...

Aims: The aim of this study was to isolate essential oils from the fruits of Fissistigma bracteolatum and Fissistigma maclurei (Annonaceae) and investigate the volatile constituents present they contained. Study Design: The study involves the hydrodisitillation of essential oils from the air-dried fruit samples of F. bracteolatum and F. maclurei and analysis of their chemical compositions by GC...

Scutellaria is widely used in traditional medicine as a medical plant, in Asian countries, especially in China. It has been applied in treatment because of its sedative, antithrombotic, anti-inflammatory, antioxidant, and antiviral effects. Scutellaria condensata Rech. f. subsp. pycnotricha (Rech. f.) Rech. f. is a wild perennial plant which  grows in Iran. In this study, GC-FID and GC-MS were ...

Streptomyces clavuligerus is a member of the Actinobacteria family primarily known for its production clavulanic acid antibiotic. The need identification new antimicrobials led to volatile components S. metabolites using GC-MS. isolate was obtained from Ocimum gratissimum rhizosphere starch casein agar, and identified molecular typing. preliminary antibacterial screening carried out some indica...

Plants are an abundant natural source of effective antibiotic compounds. Phytomedical investigations of certain plants haven't still been conducted. One of them is Najas minor (N. minor), an aquatic plant with confirmed allelopathy. Research conducted in this study showed the influence of water and ethyl acetate extracts of N. minor on microorganisms, in the view of chemical profiling of volati...
