Thermal treatment under oxidative conditions increases the antioxidant and antiglycation activity of Chilean Tórtola beans (Phaseolus vulgaris).

The influence of oxygen on the thermal treatment (TT) of secondary metabolite-enriched extracts (SMEEs) from Tórtola beans and procyanidin C1 (PC1) on the inhibition of advanced glycation end products (AGEs) generation in proteins was investigated. SMEE was incubated at 4 °C (control) or thermally treated at 60 °C for 2 h, at either 0 % O (I) or 20 % O (II). Treatments I and II increased the content of procyanidin dimers B2.

Identification of and subtype ST3 in Cholga mussel and treated sewage: Preliminary evidence of fecal contamination in harvesting area.

and are foodborne parasites known for causing diarrhea. They accumulate in mussels grown on contaminated water bodies, due to the discharge of treated sewage from sewage treatment plants (STP). Despite this, some countries like Chile do not include these parasites in the control or monitoring of sewage water.

Application of effect-directed analysis using TLC-bioautography for rapid isolation and identification of antidiabetic compounds from the leaves of Annona cherimola Mill.

Introduction: Type 2 diabetes mellitus is a globally prevalent chronic disease characterised by hyperglycaemia and oxidative stress. The search for new natural bioactive compounds that contribute to controlling this condition and the application of analytical methodologies that facilitate rapid detection and identification are important challenges for science. Annona cherimola Mill.

Antioxidant Compound Adsorption in Polyvinylpolypyrrolidone from Chilean and Grape Pomaces as Potential By-Products.

Grape pomace (GP) is a by-product resulting from the winemaking process and its potential use as a source of bioactive compounds is well known. The GP bioactive compounds can be retained in the well-known polyvinylpolypyrrolidone (PVPP), industrially used in the clarification and stabilization of wine and other drinks. Thus, the polyphenolic compounds (PC) from the Chilean , , and GP were extracted, and their compositions and antioxidant capacities (ORAC-FL) were determined.

Advances in analytical techniques coupled to in vitro bioassays in the search for new peptides with functional activity in effect-directed analysis.

Bioactive peptides derived from food proteins have important biological effects. The search for new bioactive peptides from natural sources needs to base their decisions on evidence from methods providing structural information, where classic biological assays do not provide it. In this context, high-performance thin-layer chromatography (HPTLC) coupled with bioassays in effect-directed analysis (EDA) has been used recently to detect the bioactivities of peptides.
