Resumen de Lectin prospecting in colombian labiatae. A systematic-ecological approach – iii. Mainly exotic species (cultivated or naturalised)
José Luis Fernández-Alonso, Nohora Vega, Gerardo Pérez
This is the third study of lectin and mucilage detection in Labiatae nutlets fromColombia. It was carried out on 30 taxa; 15 of them belonging to 14 genera inwhich no previous studies have been carried out in this fi eld, the other 15 belongingto previously studied genera. A differential response was observed in the group ofgenera and species studied in terms of mucilage presence as well as lectin activitywhich consistently increased after extract treatment with Pectinex. Lectin activity wasdetected in 26 species, being important (more than 60% activity) in at least 75% ofthem. Genera such as Aegiphila, Agastache, Ballota, Mentha and Origanum, whilstnot presenting mucilage, did present lectin activity, with high activity in most cases.This is the fi rst time that a lectin has been reported in these genera. Salvia (in all butSalvia sections studied) presented mucilage and important lectin activity.
