Preliminary Analysis of Unsaturated Fatty Acid Profiles of Coffea arabica L., in Samples with a Denomination of Origin and Speciality of Oaxaca, Mexico.

In February 2020, Coffea arabica L. grown on the coast and in the Southern Sierra Madre of the state of Oaxaca, Mexico obtained the denomination of origin. Which does not have data on color and chemical composition, the first associated with the degree of roasting and the second with lipids (17-18%), as the group of compounds responsible, in part, for flavor, consistency, and may contribute to health benefits.

Chemical Characterization of Plant Extracts and Evaluation of their Nematicidal and Phytotoxic Potential.

ranks among the "top ten" plant-parasitic nematodes of phytosanitary importance. It causes significant losses in commercial interest crops in America and is a potential risk in the European Union. The nematicidal and phytotoxic activities of seven plant extracts against and were evaluated in vitro, respectively.

Origin, structural characteristics, prevention measures, diagnosis and potential drugs to prevent and COVID-19.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) causes COVID-19 (Coronavirus disease 2019). This disease was detected in the city of Wuhan in China in December 2019. People infected with COVID-19 shows varying manifestations, depending on their health and age.

Characterization of pectin extracted under mild conditions from tempesquistle (Sideroxylon palmeri) fruit at two maturity stages.

Background: le tree (Sideroxylon palmeri) belongs to family Sapotaceae, and its fruits contain hydrophilic and hydrophobic gums. Aim of this study was to develop an extraction method for pectin, a hydrophilic gum, from green and ripe tempesquistle fruit. The extraction method was gentle to minimize potential structural changes in pectin, a maceration was used, and then pectin precipitation was induced with acetone at room temperature.

Productivity and Antioxidant Activity of Wild, Reconstituted, and Hybrid Strains of the Pink Oyster Mushroom, Pleurotus djamor (Agaricomycetes), from Mexico.

The genus Pleurotus is the third most commonly produced edible fungi in the world. In addition, species of genus Pleurotus have functional properties such as anticancer, antiviral, antimicrobial, anti-inflammatory, and antioxidant activities, which are mainly attributed to phenolic compounds. For these reasons, this study evaluated the productivity and antioxidant activity (AA) of 2 wild strains (white and pink), 2 reconstituted strains (called "BB" and "RR"), and 4 hybrid strains (H1, H2, H3, and H4) of P.
