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 app...
Introduction: Fruit polysaccharides, essential health factors in foods, are widely present in edible fruits. Several methods for isolation of polysaccharide are available. Microwave Assisted Extraction (MAE) method is extensively used for separation of polysaccharides. Only little information is available about Psidium guajava L. Fruit Polysaccharide (PFP) and its extraction methods. Objective:...

Quercetin is a biological flavonoid, which can be found in red kidney bean at high concentration. In this study, a comparison was conducted between traditional and modern extraction methods. Sequential microwave-assisted extraction was used for isolation of quercetin from red kidney bean. The effect of several factors such as particle size of grinded kidney bean, extraction solvent, microwave p...
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...
Mangiferin, a bioactive compound having potent nutraceutical, strong antioxidant and pharmacological significance has been extracted using microwave-assisted extraction (MAE) technique from Curcuma amada, commonly known as mango ginger. The extraction solvent ethanol is eco-friendly, nontoxic and reduces the risk of environmental hazards. The influence of several independent variables such as m...
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...
microwave assisted green synthesis of α, ά- bis (substituted- benzylidene) alkanones by the crossed- aldol condensation reaction of substituted aryl aldehydes with ketones in the presence of catalytic amount of nbcl5 in good to excellent yields. this reaction is carried out under solvent-free conditions. the results showed that aldehydes bearing electron–donating substituent's on phenyl-ring fa...
