in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
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...
Durio zibethinus L. (durian) belongs to the Malvaceae family. It is known as “King of Tropical Fruit” because its unique characteristics. The edible part durian, however, only about 33% fruit while non-edible parts such seed and peels (rinds) are considered waste responsible for environmental pollution. Thus, present study was carried out compare percentage yields volatile components from metha...
The orange tree (Citrus sinensis) is a species of fruit shrubs the Rutaceae family. Essential oils from citrus peels are widely used in various agro-food and pharmaceutical preparations hence they must be recovered using green extraction methods. In this study, we compare efficiency five techniques (conventional hydro-distillation (HD), Salt-assisted by HD (S-HD), Ultrasound-assisted (US-HD), E...

'Mato Peiyu' pomelo (Citrus grandis (L.) Osbeck 'Mato Peiyu') leaves from pruning are currently an agricultural waste. The aim of this study was to isolate essential oils from these leaves through steam distillation (SD) and solvent-free microwave extraction (SFME) and to evaluate their applicability to skin care by analyzing their antimicrobial, antioxidant (diphenyl-1-picrylhydrazyl scavengin...
Abstract Gotu Kola (Centella asiatica L.), known as pegagan is a plant with many benefits, including used to repair burns, hypertrophic wound healing, and an inflammatory agent. C. grows in tropical Asia various countries such Indonesia, Philippines, China, India, Sri Lanka, Madagascar. has four bioactive components, namely asiatic acid, asiaticoside, madecassic madecassoside. Microwave-Assiste...

 Purpose: To investigate the effect of different soil textures on chemical composition and antioxidant properties essential oils from Solanum nigrum.
 Methods: Four soils differing texture were formulated under fallow to cultivate S. nigrum in a glasshouse. Essential Oil was extracted fresh shoots by solvent-free microwave extraction (SFME) analysed using gas chromatography-mass spec...
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...
