Resumen:
Plantago L. is a cosmopolitan genus with economical andmedicinal importance worldwide. Seeds of many species of Plantago are mucilaginous and have been used as bulk laxative. Tenspecies inhabit Córdoba and adjacent provinces, six of them have been reported asmedicinal plants. However, the seed mucilage of only two species were studied.The main goal of this work is to analyze the variability in mucilage productionof four local species (P. australis, P.brasiliensis, P. major, and P. tomentosa)and the most marketed species (P. ovata).Mature seeds of the local species were collected in Córdoba hills and seeds of P. ovata were bought in an herbal store.We applied three different techniques to analyze the mucilage production: swellingfactor, analysis of the seed mucilage halo related to seed area, and aqueousextraction of mucilage. Besides, weight and size of seeds were quantified inorder to know whether there is a relationship among these variables andmucilage production. Three to five replicates of each species werestatistically analyzed. We found out that P.major and P. brasiliensis are thespecies with the highest swelling factor and halo/seed area rate, and werestatistically different from the other species, showing P. ovata and P. tomentosa thelowest values of these variables. Regarding to the mucilage content through theaqueous extraction, no significative differences were found among the species. Nevertheless,this lack of significance could be produced by chemical variables which needfurther research. According to our results, we recommend P. brasiliensis and P. major forbioprospecting studies in their seed mucilage.
