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:...

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...

The major challenges for industrial commercialized biodiesel production from microalgae are the high cost of downstream processing such as dewatering and drying, utilization of large volumes of solvent and laborious extraction processes. In order to address these issues the microwave irradiation method was used to produce biodiesel directly from wet microalgae biomass. This alternative method o...

Microwave-assisted extraction was used for the extraction of alantolactone and isoalantolactone from Inula helenium. Effects of various experimental factors including ethanol concentration, particle size, microwave radiation time, the ratio of material to liquid and extraction temperature on yield of alantolactone and isoalantolactone were evaluated. The optimal extracting process of the alanto...

ABSTRACT: Chemical composition of Lavandula angustifolia was studied by solvent free microwave extraction (SFME) and hydrodistillation (HD) methods. 1, 8-cineole (42.7% and 37.9%), Camphor (26.1% and 21.3%) and Borneol (31.2% and 21.6%) were the major compounds that obtained by SFME and hydrodistillation, respectively. The antibacterial activity of extracted oils was investigated against Gram-p...

Microwave extraction of phytochemicals from medicinal plant materials has generated tremendous research interest and shown great potential. This research highlights the importance of microwave extraction in the analysis of flavonoids, isoflavonoid and phenolics and the antioxidant properties of extracts from three varieties of the Malaysian medicinal herb, Labisia pumila Benth. High and fast ex...

Oleanolic acid and ursolic acid are the main active components in fruit of Ligustrum lucidum Ait, and possess anticancer, antimutagenic, anti-inflammatory, antioxidative and antiprotozoal activities. In this study, microwave-assisted extraction of oleanolic acid and ursolic acid from Ligustrum lucidum was investigated with HPLC-photodiode array detection. Effects of several experimental paramet...

A microwave assisted extraction technique was developed to optimize the extraction of mucilage from the fruits of Abelmoschus esculentus plant. The plant has been extracted by conventional and microwave assisted methods for the isolation of mucilage. Microwave extraction at 160 W intensity and 40 min heating duration increase 11.55% in the yield of mucilage when compared to 1 h conventional hea...

the aim of this study was to extract phenolic compounds from olive leaves of cronaiky, roghani and mishen varieties by maceration and microwave-assisted extraction (mae) methods. our result revealed that effect of extraction method and variety was statistically significant (p<0.05) and mae-produced extracts have more total phenolics and antioxidant activity than traditional ones. the highest ph...
