The study aimed to evaluate extraction efficiency, detection and quantification of phytochemicals, minerals and antioxidative capacity of different parts of Salacia chinensis L. Continuous shaking extraction, steam bath assisted extraction, ultrasonic extraction and microwave assisted extraction with varied time intervals were employed for extraction of phenolics, flavonoids, and antioxidants. ...

essential oils from aerial parts of mentha spicata, was obtained by steam destillation using a clevenger-type system. these oils were screened for antibacterial and anti-candida albicans activity using bioautographic method. a fiel experiments was laid out in agricultural research farm, city namin, ardabil province, iran in 2013. experiment was conducted in a randomized complete block with seve...

The effects of enzyme action and heat pretreatment on oil extraction yield from sunflower kernels were analysed using hexane extraction with Soxhlet, and aqueous extraction with incubator shaker. Ground kernels of raw and heat treated kernels, each with and without Viscozyme treatment were used. Microscopic images of the kernels were taken to analyse the visible effects of each treatment on the...

A review of the literature and discussions with plant operators has been undertaken to establish present knowledge and understanding of the chemistry of the condensates formed on steam turbines and the link to system operation. This has been supplemented by an overview of the effect of test variables on environment assisted cracking. In Section 1, steam turbine operating conditions are describe...
