MetadataShow full item record
This is the second study of lectin and mucilage detection in Labiatae nutlets fromColombia. It was carried out on 31 taxa belonging to 7 genera in which no previousstudies have been carried out in this field. A differential response was observedin the group of genera and species studied in terms of mucilage presence as wellas lectin activity which consistently increased following extract treatment withPectinex. Lectin activity was detected in 28 species, being important (greater than60% activity) in at least 75% of them. Genera such as Hyptis, Scutellaria, Aegiphilaand Lepechinia, whilst not presenting mucilage, did present lectin activity, havinghigh activity in most cases. By contrast, Salvia (in all sections studied) presentedmucilage and important lectin activity.
