Medicinal plants are sources of crude traditional herbal medicines that utilized to reduce the risk of, treat, or manage diseases in most indigenous communities. This is due their potent antioxidant and anti-inflammatory effects. It estimated about 80% population developing countries rely on for healthcare. signifies need medicines, which polyherbal formulations prepared by health practitioners. review examines preparatory steps extract bioactive phytoconstituents post-extraction processes increase potency extracted phytoconstituents. Achieving this will allow reduced use plant materials promote sustainable limited resource medicinal plants, especially our South African context.

Kinetics of Macroion Adsorption on Silica: Complementary Theoretical and Experimental Investigations for Poly-l-arginine

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 21, 2025

A comprehensive approach enabling a quantitative interpretation of poly-l-arginine (PARG) adsorption kinetics at solid/electrolyte interfaces was developed. The first step involved all-atom molecular dynamics (MD) modeling physicochemical characteristics yielding PARG molecule conformations, its contour length, and the cross-section area. It also shown that molecules, even in concentrated electrolyte solutions (100 mM NaCl), assume largely elongated shape with an aspect ratio 36. Using parameters derived from MD, silica/electrolyte interface calculated using random sequential approach. These predictions were validated by optical reflectometry measurements. confirmed molecules irreversibly adsorbed side-on orientation their coverage agreed predicted MD modeling. theoretical experimental results used for quartz crystal microbalance measurements carried out under various pH conditions. analysis unveiled stemming hydrodynamic theory postulating lubrication-like (soft) contact macroion sensor adequately reflect kinetics. range validity intuitively Sauerbrey model estimated. argued acquired can be exploited to control solid/liquid interfaces. This is essential optimum preparation supporting layers bioparticle immobilization shell formation nanocapsules targeted drug delivery.

Microwave Cold Maceration: Effects on the Colour and Mouthfeel Characteristics During the Ageing Stage of Merlot Wine

Journal of Food Processing and Preservation, Journal Year: 2025, Volume and Issue: 2025(1)

Published: Jan. 1, 2025

Cold maceration technique could increase the contents of active ingredients such as phenols, tannins, and flavan‐3‐ol in grape must, which contributed to sensory characteristics wine. This study investigated colour mouthfeel Merlot wine after different treated techniques. When musts were fermented wine, microwave cold had been proven have a positive effect on extraction into resulting significant visible spectrum, BI, L ∗, total ECG, WC, CI, while fluorescence b anthocyanins, flavan‐3‐ols, C, EC showed decreasing trend during 120 days ageing storage, compared with without maceration. These results indicated that improve Based this study, potential industrial application was worth further investigation winemaking.
