Effects of Annual Growth Conditions on Phenolic Compounds and Antioxidant Activity in the Roots of .

Medicinal plants grown in natural settings are exposed to different adverse environmental conditions that determine their growth and development as well as the composition and concentration of secondary metabolites in their organs. The objective of this study was to evaluate the effects of environmental conditions associated with localities and annual growth cycles on the contents of phenolic compounds and flavonoids, antioxidant activity and potentially bioactive phenolic acids in the roots of , a medicinal species from temperate Mexico. The samples for composition analysis were collected using a bifactorial design: Factor A consisted of the localities (Morelos and La Unión de San Martin Huamelulpam, Mexico) and Factor B was represented by the annual growth cycle (2020 and 2021).

Edible Leafy Plants from Mexico as Sources of Antioxidant Compounds, and Their Nutritional, Nutraceutical and Antimicrobial Potential: A Review.

A review of indigenous Mexican plants with edible stems and leaves and their nutritional and nutraceutical potential was conducted, complemented by the authors' experiences. In Mexico, more than 250 species with edible stems, leaves, vines and flowers, known as "," are collected or are cultivated and consumed. The assessment of the quelite composition depends on the chemical characteristics of the compounds being evaluated; the protein quality is a direct function of the amino acid content, which is evaluated by high-performance liquid chromatography (HPLC), and the contribution of minerals is evaluated by atomic absorption spectrometry, inductively coupled plasma-optical emission spectrometry (ICP-OES) or ICP mass spectrometry.

Complementarity in Phenolic Compounds and the Antioxidant Activities of L. and L. Landraces.

L. is one of the most consumed and documented legumes in regard to its grain composition, but little is known about L. To evaluate and compare the phenolic compound content and antioxidant activity between landraces of and , a total of 14 accessions of and were collected from farmers in Oaxaca, Mexico.
