Processing of plant sample for extraction of protein is usually divided into three steps, i.e., defatting of sample, extraction and precipitation of protein. In defatting, solvents like petroleum ether, n-hexane and n-pentane are used to remove the compounds that interfere with protein extraction.

The properties of the new generation of fluorocarbon solvents have been applied to the extraction of plant materials. The core of the solvent is 1,1,2,2-tetrafluoroethane, better known as hydrofluorocarbon-134a (HFC-134a).

2.3. Ultrasonic-Assisted Extraction. Ultrasound-assisted extraction (UAE) has been used in diverse applications of food-processing technology to extract bioactive compounds from plant materials [].Ultrasound, with levels greater than 20 kHz, is used to disrupt plant cell walls, which helps improve the solvent's ability to penetrate the cells and obtain a higher extraction …

Phenolics are broadly distributed in the plant kingdom and are the most abundant secondary metabolites of plants. Plant polyphenols have drawn increasing attention due to their potent antioxidant properties and their marked effects in the prevention of various oxidative stress associated diseases such as cancer.

Phytochemicals: Extraction Methods, Basic Structures and Mode of Action as Potential Chemotherapeutic Agents James Hamuel Doughari Department of Microbiology, Sch ool of Pure and Applied Sciences, Federal University of Technology, Yola Nigeria 1. Introduction Medicinal plants have been the mainstay of traditional herbal medicine amongst rural

The extraction mostly is based on a physically transfer from the original plant material into another phase which can be separated by filtration. This can be a liquid or even gas depending on the physical properties of the desired compound and the used method. Most common is for the start to use a mixture of organic solvent as ethanol or acetone.

tion plant consists of an extraction unit, distillation units and other related units such as strippers and settlers. The extraction plant in-cludes critical unit operations such as extraction, distillation and ab-sorption [Cho et al., 1999]. Fig. 1 shows a schematic diagram of the sulfolane extraction plant.

The conventional extraction methods, including maceration, percolation and reflux extraction, Some modern or greener extraction methods such as super critical fluid extraction (SFC), pressurized liquid extraction (PLE) and microwave assisted extraction (MAE),are adopted for extracting desired components from natural products.

There are concerns about using synthetic phenolic antioxidants such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) as food additives because of the reported negative effects on human health. Thus, a …

Plant materials with high content of phenolic compounds and flavonoids were found to possess antioxidant properties, and hence are used to treat age-related diseases such as Alzheimer's disease, Parkinsonism, anxiety, and depression.[2,5] Several methods were used in the extraction of medicinal plants such as maceration, infusion, decoction ...

Extraction is the separation of medicinally mixture of many plant metabolites, such as alkaloids, glycosides, phenolics, terpenoids, and flavonoids using selective solvents through standard procedures . The aim of all solvent extraction methods is to separate the soluble plant metabolites, leaving behind the insoluble cellular marc.

SOLVENT EXTRACTION. This method employs food grade solvents like hexane and ethanol to isolate essential oils from plant material. It is best suited for plant materials that yield low amounts of essential oil, that are largely …
