Insulin-Sensitizing Properties of Decoctions from Leaves, Stems, and Roots of L.
Molecules
December 2024
Department of Biochemistry, School of Medicine, College of Health Sciences, Addis Ababa University, Addis Ababa P. O. Box 9086, Ethiopia.
Type 2 diabetes mellitus (T2DM) is a chronic disease characterized by insulin resistance and impaired beta-cell secretory function. Since existing treatments often present side effects based on different mechanisms, alternative therapeutic options are needed. In this scenario, the present study first evaluates the cytotoxicity of decoctions from the leaves, stems, and roots of L.

In this work, a DNPH doped PDMS based membrane was developed to facilitate carbonyl compound derivatization. This membrane delivers DNPH in presence of carbonyl compounds to form hydrazones. Subsequently, the resulting hydrazones are preconcentrated, separated and detected by in-tube solid phase microextraction (IT-SPME) coupled on-line with capillary liquid chromatography (CapLC) with Uv-Vis diode array detection (DAD).

The study evaluates different preparation methods for identifying the best strategy for extracting biologically active compounds from raw (L.) Holub plant material. The methodologies include direct aqueous methanol extraction with a combination of natural aerobic and anaerobic fermentation for 24-72 h, followed by 35 °C and 60 °C drying.

Artificial sweeteners (ASs) and dyes are widely used in foods, beverages and pharmaceutical and are recognized as emerging environmental contaminants due to their persistence and widespread occurrence. These substances often pass through the human body unchanged and resist wastewater treatment processes, leading to continuous introduction into aquatic environments and potential long-lasting term environmental effects. This study investigated, for the first time, the biodegradability of nine commercial dietary supplements, both natural and those containing ASs and synthetic dyes, using the Organisation for Economic Cooperation and Development (OECD) 301 F ready biodegradation test (RBT), which is a respirometry-manometric method.

In recent years, increased attention has been paid to the recovery of bioactive compounds from waste and by-products resulting from the agro-industrial sector and their valorization into new products, which can be used in the health, food, or agricultural industry, as innovative and sustainable approaches to waste management. In this work, two of these by-products resulting from the fruit-processing industry were used for the recovery of bioactive compounds (polyphenols), namely lingonberry pomace () and grape pomace (). Two green extraction techniques were employed to obtain hydroalcoholic extracts (solvent: 50% EtOH, 10% mass): ultrasound-assisted extraction (UAE) and accelerated solvent extraction (ASE).
