The genus Haplophyllum, which belongs to the Rutaceae family, includes 18 species in Iran. In this study, after collecting plant material, botanical identification and suitable drying, the essential oils from aerial parts of Haplophyllum robustum Bge. were extracted by three different isolation techniques, conventional hydrodistillation (HD), microwave-assisted hydrodistillati...
background & aim: a simple and rapid microwave- assisted extraction (mae) procedure was developed and optimized for the isolation of borneol and bornyl acetate from ferulago macrocarpa. ferulago macrocarpa (apiaceae) is an endemic plant in iran. experimental: dried powdered aerial parts of plants were soaked in water and irradiated with microwave in a clevenger extraction approach under opt...

Jatropha curcas has a variety of uses which are of great economic significance. Jatropha oil can be used as fuel alternative and for making biodiesel that is supposed to overcome the source limitation problem. In this study, conventional, ultrasound assisted and microwave pretreatment solid liquid extraction of Jatropha seed were studied in terms of amount and quality of the extracted oil. The ...
The use of rangeland medicinal plants and their active ingredients has recently been considered due to their therapeutic and industrial effects. In order to investigate the effect of height, plant limb, solvent and extraction method on some phytochemical properties of Verbascum speciosum in Chaharbagh rangelands, Golestan province, flower and leaf samples of this species were collected from alt...
the lamiaceae family consists of a broad spectrum of medicinal plants involving marrubium l. genus. regarding the diverse pharmaceutical uses of the plants belonging to this genus, they can be considered as proper alternatives for chemical drugs having harmful effects. the present work aims to identify and characterize chemical compositions of the essential oils and volatiles from the aerial pa...
This article describes the various chemical components as obtained from the oils in the leaves of Cymbopogon citratus using hydrodistillation and solvent-free microwave extraction methods. Furthermore, extractions of the oils were also carried out with a slight in pH variation and compared, "GC-MS evaluation of C. citratus (DC) Stapf oil obtained using modified hydrodistillation and microwave e...
This research was undertaken to investigate the influence of extraction parameters during microwave-assisted extraction on total phenolic content, total flavonoids, total hydroxycinnamic acids and total flavonols of blackthorn flowers as well as to evaluate the antioxidant capacity by two different methods (2,2-diphenyl-1-picrylhydrazyl free radical scavenging capacity and ferric reducing antio...
microwave-assisted hydrodistillation (mahd) method has been compared with hydrodistillation (hd) conventional technique for extraction of essential oil from achillea millefolium. microwave-assisted hydrodistillation were examined at three levels of microwave powers (300, 500, and 700 w) . obtained results show that mahd offers important advantages over hd in terms of energy savings and extr...
