A Comparative Study on the Antidiabetic Activity, Cytotoxicity and Lipid Profile of Oils.

The plant is traditionally used for medicinal and food purposes. However, there are limited studies on the bioactivity and cytotoxicity of its seed butter and aril oil. This study aimed to assess the antidiabetic activity and cytotoxicity of seed butter and aril oil, obtained via two different extraction methods, and compare their lipid profiles.

Antidiabetic and Anticancer Potentials of L. from Different Geographical Origins.

Mango fruit is well known for its nutritional and health benefits due to the presence of a plethora of phytochemical classes. The quality of mango fruit and its biological activities may change depending upon the variation in geographical factors. For the first time, this study comprehensively screened the biological activities of all four parts of the mango fruit from twelve different origins.

The effect of natural antioxidants, pH, and green solvents upon catechins stability during ultrasonic extraction from green tea leaves (Camellia sinensis).

Background: This is a first-time report to evaluate the effect of natural antioxidants, pH, and green solvents upon catechins yield and stability during the active process of extraction from green tea leaves.

Methodology: Green solvents (model-A) augmented with piperine (PPN) and quercetin (QT) as natural antioxidants (model-B) at different pH 2-6 (model-C) were used to extract catechins from green tea leaves using an ultrasonic extraction process (USE). For quantification of catechins (EC; epicatechins, ECG; epicatechin gallate, and EGCG; epigallocatechin gallate), a green and sensitive UHPLC-MS/MS method was developed and validated.

Biological Screening of L. from Different Origins for Antidiabetic and Anticancer Activity.

Background: Geographical variation may affect the phytochemistry as well as the biological activities of Glycyrrhiza glabra (licorice) root. Herein, a series of biological activities were performed to evaluate the impact of geographical origin on the biological potential of eight different licorice samples.

Methodology: Cell culture studies were performed for cytotoxicity (MCF7, HCT116, HepG2, and MRC5), glucose uptake assay (HepG2), and glutathione peroxidase activity (HepG2), whereas α-amylase inhibition activity was tested for antidiabetic potential.
