Acylated iridoid glycosides from Scrophularia saharae Batt. & Trab.

► We study the chemical composition of Scrophularia saharae Batt. & Trab. ► Five iridoid glycosides are isolated and identified. ► One acylated iridoid with catalpol skeleton is new. ► The study confirms that iridoids are chemotaxonomic markers of the family Scrophulariaceae.
