•Ethanolic extracts from Nardophyllum bryoides was investigated as antifoulants.•Secochiliolide acid was identified as the main component from N. bryoides.•Antifouling performance of secochiliolide acid was evaluated in rosin-based coatings.•Secochiliolide acid exhibited more promising result against micro and macrofouling.•This study identified to terrestrial plants as a sustainable source of antifoulants.
Environmental concerns about the use of toxic antifoulants have led to an increased interest in the development of new alternatives. So far, most of the antifouling natural products have been obtained from marine organisms. However, some secondary metabolites from terrestrial plants could be promising antifoulant candidates. The antifouling performance of secochiliolide acid, the main component isolated from Nardophyllum bryoides ethanolic extract, was evaluated for inclusion in rosin-based coatings.Field testing was conducted during the summer months at Mar del Plata harbor, Argentina. The results indicated that secochiliolide acid-based paints completely inhibited the settlement of Bugula neritina colonies, Polydora sp., Hydroides elegans, Corophium sp. and solitary ascidians, and also reduced the attachment of some algae as Enteromorpha intestinalis and Ectocarpus sp. In addition, a lower density and diversity of microfouling species was registered.These results highlighted the importance of terrestrial plants as a sustainable source of potential environmentally friendly antifoulants.
