Bixa orellana (Bixaceae) seeds as a potential source of bioactive compounds for modulating postprandial hyperglycemia.

Background: α-Amylase (α-AMY) and α-glucosidase (α-GLU) inhibitors are important for controlling postprandial hyperglycemia (PHG). Bixa orellana (annatto) reported inhibitory activity against these enzymes because of its bioactive compound content. However, an understanding of its inhibitory mechanisms and metabolic profile is necessary to establish its therapeutic potential.

Metabolomic Diversity and Defensive Phenolic Compounds in Cloud Forest Ferns.

The few current metabolomic studies on ferns are mostly restricted to a single species or focused on specific compounds. We performed an untargeted metabolomic study on six of the most common fern species from the cloud forest, followed by a targeted analysis of 64 phenolic compounds, many of which have been associated with herbivore defense. The untargeted analysis revealed a total of 232 putatively identified metabolites from 463 to 1427 signals per fern species, each with its proper chemical signature but not necessarily correlated to their phylogenetic relationship.

Comparing and integrating TMT-SPS-MS3 and label-free quantitative approaches for proteomics scrutiny in recalcitrant Mango (Mangifera indica L.) peel tissue during postharvest period.

Despite substantial advances in the use of proteomic technologies, their widespread application in fruit tissues of non-model and recalcitrant species remains limited. This hampers the understanding of critical molecular events during the postharvest period of fleshy tropical fruits. Therefore, we evaluated label-free quantitation (LFQ) and TMT-SPS-MS3 (TMT) approaches to analyse changes in the protein profile of mango peels during postharvest period.

An Ethyl Acetate Extract of Inflorescences Attenuates Oxidative Stress and Inflammation in the Liver of Streptozotocin-Induced Diabetic Rats.

Secondary metabolites such as flavonoids are promising in the treatment of non-alcoholic fatty liver disease (NAFLD), which is one of the complications of diabetes due to oxidative stress and inflammation. Some plants, such as , have been investigated regarding their medicinal properties in in vitro and in vivo assays, showing favorable results for the treatment of various diseases such as diabetes and obesity. The present study examined the antioxidant and anti-inflammatory effects of the phenolic compounds present in an ethyl acetate extract of the inflorescences of on liver homogenates and mitochondria from streptozotocin (STZ)-induced diabetic rats.

Bioassay-guided identification of antithrombotic compounds from (Mill.) I. M. Jhonst.: molecular docking, bioavailability, and toxicity prediction.

In vitro Evaluation of Anti-Inflammatory Activity of "Habanero" Chili Pepper (Capsicum chinense) Seeds Extracts Pretreated with Cellulase.

The aim of this study was to explore the effect of capsaicin and particular phenolic compounds profile from cellulase assisted extracts of Habanero (Capsicum chinense) chili pepper seeds (CPS) on the concentration of cytokines (IL-2, IL-6, TNF-α, IL-1β) in murine macrophages (RAW 264.7) stimulated with lipopolysaccharides (LPS). Capsaicin was quantified by HPLC-DAD, and the phenolic profile was determined by UPLC-MS-QqQ.

The use of ecological analytical tools as an unconventional approach for untargeted metabolomics data analysis: the case of Cecropia obtusifolia and its adaptive responses to nitrate starvation.

Plant metabolomics studies haves revealed new bioactive compounds. However, like other omics disciplines, the generated data are not fully exploited, mainly because the commonly performed analyses focus on elucidating the presence/absence of distinctive metabolites (and/or their precursors) and not on providing a holistic view of metabolomic changes and their participation in organismal adaptation to biotic and abiotic stress conditions. Therefore, spectral libraries generated from Cecropia obtusifolia cell suspension cultures in a previous study were considered as a case study and were reanalyzed herein.
