Abstract In the current study, we used high-performance liquid chromatography (HPLC) and gas chromatography–mass spectrometry (GC–MS) to investigate analyze methanolic extract of Salvia rosmarinus leaves. HPLC analysis showed that revealed a diverse array polyphenolic compounds, including apigenin, catechin, chlorogenic acid, cinnamic caffeic coumaric daidzein, ellagic ferulic gallic hesperetin...

Plant Based Natural Products (PBNPs) have contributed to the development of drugs for diverse indications. Worldwide interest in use PBNPs has been growing, and its beneficial effects being rediscovered drug leads. Literature survey on indigenous traditional knowledge bestows ethnopharmacological potentials PBNPs, inspired research design discovery; provide a baseline novel leads against variou...

Wedelia trilobata is an invasive weed of the family Asteraceae.Objective study was to find out impact essential oil on germination and seedling growth cowpea. Different concentrations oil(200, 400, 600, 800 1000ppm) were used,a controlwas kept without oil. Cowpea seeds sown in these petriplates,at end test period all parameters measured. All showed that treatment had no negative germination. Wh...

Background: Nitric oxide is a free radical that recently has emerged as a key signaling molecule in regulating important physiological processes in plants. Objective: In this work, sodium nitroprusside (SNP) was utilized as the donor of nitric oxide to investigate the effects of exogenous nitric oxide on essential oil, rosmarinic acid and antioxidant activity of in vitro-cultured Melissa offi...

Objetvo: realizar caracterização química o potencial microbiológico do óleo essencial de Piper arboreum (EOPa), fornecendo dados possibilite desenvolvimento u...

essential oil extracted from the leaves of lemon verbena, lippia citriodora kunth (verbenaceae) was tested for fumigant toxicity in the laboratory against two stored-product insects tribolium confusum jacquelin du val and callosobruchus maculatus (f.). the chemical composition of the isolated oil was examined by gc-ms. the major compounds were citral (11.3%), limonene (10.6%), neral (7.9%), 4-p...

Fresh leaves of Litsea glutinosa (Lour.) C. B. Rob. from Ha Tinh were steam distilled to produce an oil in 0.15% yield. The essential oil was analysis by a combination of capillary GC and GC/MS. Seventy eight compounds were detected in the oil, of which more than 95.18% were terpenoids. The major components were (E)-β-ocimene (13.35%), β-caryophyllene (27.20%) and bicyclogermacrene (18.16%). Ke...

The genus Artedia L. (Apiaceae) is represented in Turkey by 485 species and altogether 511 taxa. rate of endemism 37.7%. plant material was collected from the province Kahramanmaraş, Turkey. essential oils fruits aerial parts were obtained hydrodistillation using a Clevenger type apparatus. Chemical compositions analysed GC-FID GC-MS techniques. main components oil characterized as 1-octadecano...

When plants receive volatiles from a damaged plant, the receivers become more resistant to herbivory. This phenomenon has been reported in many plant species and called plant-plant communication. Lab experiments have suggested that several compounds may be functioning as airborne signals. The objective of this study is to identify potential airborne signals used in communication between sagebru...
