Radix Puerariae (RP), a traditional Chinese medicinal herb, has been used for a variety of disease prevention and treatment purposes. Three isoflavones, puerarin, daidzin and daidzein, isolated from RP are responsible for its broad therapeutic effects. In the present study, we demonstrate the application of three extraction methods, traditional, pressurized solvent extraction (PSE) and ultrason...

Oleanolic acid and ursolic acid are the main bioactive compounds in fruit of Ligustrum lucidum Ait, which possess anti-inflammatory, antioxidative, antiprotozoal, antimutagenic and anticancer properties. In this study, the ultrasound-assisted extraction of oleanolic acid and ursolic acid from L. lucidum Ait was investigated with HPLC-photodiode array detection. Effects of several experimental p...

Single-factor experiment and Box-Behnken design were applied to optimize the infrared-assisted extraction (IRAE) of rutin, quercetin, kaempferol, and isorhamnetin from Flos sophorae. Four factors (extract solvent, solid-liquid ration, extraction time, infrared power) affecting the extraction yield of flavonoids were studied. Under optimized conditions the extraction yield was 33.199 ± 0.24 mg/g...

Resveratrol is a natural compound that has many beneficial physiological functions. In recent years, the research on resveratrol gradually become hotspot. This article summarized literature reports all over world, classified and concluded extraction technology, function nano-delivery carriers of resveratrol. Solvent extraction, microwave-and ultrasonic-assisted supercritical carbon dioxide enzy...

Supercritical fluid extraction (SFE), ultrasonic extraction (USE), and accelerated solvent extraction (ASE) were compared with the well known Soxhlet extraction for the extraction of polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins (PCDDs) from the XAD-2 resin which was used to adsorb PCDDs in the atmosphere. XAD-2 resin spiked with five PCDDs was chosen as a sample. The o...

INTRODUCTION The objective of this study was to compare three capsaicin extraction methods: Shoxlet, Ultrasound-assisted Extraction (UAE), and Shaker-assisted Extraction (SAE) from Habanero pepper, CNPH 15.192. MATERIALS AND METHODS The different parameters evaluated were alcohol degree, time extraction, and solid-solvent ratio using response surface methodology (RSM). RESULTS The three par...

Marine ecosystems cover more than 70% of the globe's surface. These habitats are occupied by a great diversity of marine organisms that produce highly structural diverse metabolites as a defense mechanism. In the last decades, these metabolites have been extracted and isolated in order to test them in different bioassays and assess their potential to fight human diseases. Since traditional extr...

Background: Green extraction involves using green solvents, such as water, to reduce energy consumption, avoid health and environmental hazards induce the quality quantity of extract. Date palm fruits are a vital source food medicinal activities, they contain high diversity phytochemicals, mainly phenolic flavonoid compounds. The main aim this study is investigate use water solvent, when assist...

Polyphenols, as plant secondary metabolites, achieve strong antioxidant capacity by scavenging free radicals, chelating metals, and interacting with lipid membranes, proteins nucleic acids. The aim of the present study was examination applied extraction conditions (particle size material, solvent-to-solid ratio, solvent type, time) techniques (maceration, heat- ultrasound-assisted extractions) ...
