Nauclea latifolia is a valuable medicinal plant for treating different ailments. Infectious diseases constitute world health concern. This work describes the phytochemical analysis and antimicrobial properties of root N. latifolia. Collected samples were extracted via cold maceration with methanol. The methanol crude extract was fractionated into n-hexane, ethyl acetate, butanol aqueous fractio...

Cat’s claw oxindole alkaloids are prone to isomerization in aqueous solution. However, studies on their behavior in extraction processes are scarce. This paper addressed the issue by considering five commonly used extraction processes. Unlike dynamic maceration (DM) and ultrasound-assisted extraction, substantial isomerization was induced by static maceration, turbo-extraction and reflux extrac...

Grape variety has a significant impact on wine flavan-3-ol and polysaccharide profile. The main objective of this work was to study differences in diffusion from grape during the fermentative alcoholic maceration three Vitis sp. varieties: cold-hardy hybrid varieties Frontenac blanc, V. vinifera Cabernet-Sauvignon. Polysaccharides must were precipitated by ethanol quantified using phenol-sulfur...

The manufacturing processes used determined the physicochemical properties of the three kinds of rice food, garaeduk, bagsulgi, and cooked rice. The initial rate of hydrolysis by porcine pancreatic alpha-amylase (PPA) was affected by the food form. The firmer structure of garaeduk was apparently responsible for the difficulty in maceration, resulting in less digestion than with easily digestibl...

Tapinanthus globiferus is used ethnomedicinally for the treatment of bacterial infections, inflammation, stomach pain, ulcers among others. The aim study was to isolate bioactive compounds from leaf T. growing on Acacia nilotica. powdered plant material extracted with 90 % methanol using cold maceration and resulting crude extract partitioned into n-hexane, chloroform, ethylacetate n-butanol fr...
