Background. In Mexico, it is called quelites to certain edible vegetables (young plants, germ, shoots or flowers). Since pre-Hispanic times, quelites have been eaten as a source of vitamins, minerals and proteins. Now, its traditional and healthy consumption has decreased. We studied the quelites of two traditional markets in the Valles Centrales of Oaxaca state, Mexico using an ethnobotanical and nutritional approach. Methods. From July 2017 to July 2018, weekly ethnobotanical interviews were conducted with 26 collectors-sellers of the Zimatlán market and 36 in the Zaachila market. The vegetal supply was acquired, herborized and identified by through dichotomous keys. There were determined the proximal composition, phenolic compounds, flavonoids, antioxidant capacity and mineral content of the floral structures of two quelites’ types. The statistical analysis was performed through a one-way analysis of variance (ANOVA) of Tukey HSD. Results. In two sampled markets, 23 species belonging to 11 botanical families were registered, from which leaves, branches, stems, flowers and fruits are eaten. The flowers of the species Diphysa americana (Q1) and Phaseolus coccineus (Q2) are the most used for human consumption of the communities...Continue Reading
