Curcumin is a safe substance that used as food cosmetic additive and pharmaceutical product. Obtaining pure curcumin from plant sources very important for fundamental research well the above applications. Efficient extraction purification methods, which meet green chemistry criteria including safety, environment-friendliness, economic requirements, process efficiency are needed. This review pro...

Background & Aim: Sesame is one of the oldest cultivated plants in the world and is one of the oldest oily products used by humans. Sesame oil is an important industrial, oral and medicinal oil. Today, the use of ultrasound has grown significantly due to its effects on food storage and processing. Experimental: In this research, the response level model w...

The process of ultrasonic-enhanced compound-enzymes-assisted extraction of polysaccharides from the fruit of Cornus officinalis was optimized by response surface methodology (RSM). The influence of three different factors on the yield of C. officinalis polysaccharides (COP) was studied. The results showed that the optimal conditions were extraction temperature 49.6 °C, ultrasound time 40.41 min...

In this study, the effects of three different independent variables (extraction temperature, extraction time, ultrasonic power) on total phenolic content, yield and antioxidant capacity (IC50) value olive leaf extracts Halhalı variety which is originated from South-eastern Anatolia Region were investigated. As a result evaluation made with Box-Behnken Design Model, optimum conditions determined...

In this work, the antioxidant and antimicrobial activities of Brassica oleracea var. capitata extracts obtained through ultrasound-assisted extraction are evaluated. The extracts obtained using the best extraction conditions were subjected to different hydrolysis conditions before their use in the biological tests. The crude and hydrolysed extracts were characterized using gas chromatography co...

In the present study, supercritical carbon dioxide (SC-CO(2)) extraction of seed oil from winter melon (Benincasa hispida) was investigated. The effects of process variables namely pressure (150-300 bar), temperature (40-50 °C) and dynamic extraction time (60-120 min) on crude extraction yield (CEY) were studied through response surface methodology (RSM). The SC-CO(2) extraction process was mod...

In this study, the bioactive compounds of loquat fruit (Eriobotrya japonica Lindl.) skin and pulp extracted by two extraction methods (solvent and ultrasound-assisted) with three solvents (ethanol, water and ethanol-water) were compared to supercritical fluid extraction. The antioxidant activities of skin and pulp extracts were evaluated and compared to tertiary butylhydroquinone (TBHQ) using 2...

The first step in the qualitative and quantitative analysis of medicinal plant constituents is the extraction step. Ideally, an extraction procedure should be exhaustive with respect to the constituents to be analyzed, rapid, simple, and for routine analysis amenable to automation. Usually, the traditional techniques require long extraction times, with more consumption of energy resources and o...
