The 'guaco' lianous herb Mikania laevigata, which is widespread in Southern Brazil, is traditionally used to treat bronchitis, asthma and cough. This work investigates the influence of the extraction method, solvent:drug ratio, ethanol proportion, harvest season (summer or winter) and solvent heating on the physicochemical profile of the extracts (dry weight, density, pH) and the coumarin (1,2-...

abstract genomic dna extraction with high quantity and quality is the basic necessities of molecular genetic studies. the aim of this study is the applicability of different dna extraction methods as the easiest and fastest methods for and their efficiency with different tissue qualities (foot, siphon, harpoon) from marine cone snail conus coronatus, mollusca with phenol-chloroform, ammonium ac...

Two of the major factors that should be considered in leaves extraction are the solvent type and extraction method. In the current study, the effects of two solvents (Ethanol and Methanol) and two extraction methods (soaking and soxhlet) on phenolics and flavonoid contents, antibacterial and antiradical properties of extracts were investigated in a factorial experiment based on completely rando...

Aim. To investigate whether differences in the amounts of effective index components in Jakyak-Gamcho decoctions derived via extraction with either water or ethanol were associated with differential spasmolytic effectiveness. Methods. The amounts of effective index components (paeoniflorin, benzoic acid, glycyrrhizin, and isoliquiritin) contained in water-extracted Jakyak-Gamcho decoction and 7...

Sesame cake is a by-product of sesame oil industry. In this study, the effect of extraction methods (maceration and sonication) and solvents (ethanol, methanol, ethanol/water (50:50), methanol/water (50:50), and water) on the antioxidant properties of sesame cake extracts are evaluated to determine the most suitable extraction method for optimal use of this product. Total phenolic content is me...

Spruce bark is a source of interesting polyphenolic compounds and also a potential but little studied feedstock for sugar route biorefinery processes. Enzymatic hydrolysis and fermentation of spruce bark sugars to ethanol were studied after three different pretreatments: steam explosion (SE), hot water extraction (HWE) at 80 °C, and sequential hot water extraction and steam explosion (HWE+SE), ...

The extractive efficiency of phenolic compounds from plant material is greatly depended on the solvent. In our research, methanol and ethanol were used for taking out the phenols from green walnut fruits. The total phenolics and some individual phenolics, such as gallic, chlorogenic, ellagic, sinapic and protocatechuic acid, (+)-catechin and juglone were detected. Total phenolic contents were d...
