Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Chemical investigation of the glandular trichome exudate of <italic>Erodium pelargoniflorum</italic> (Geraniaceae) led to the isolation of two dodecyl disaccharide derivatives, named pelargoside A1 and pelargoside B1 (<bold>1</bold> and <bold>2</bold>, resp.). The structures of <bold>1</bold> and <bold>2</bold> were determined as dodecyl 4‐<italic>O</italic>‐acetyl‐<italic>α</italic>‐<sc>L</sc>‐rhamnopyranosyl‐(1→2)‐4‐<italic>O</italic>‐acetyl‐<italic>β</italic>‐<sc>D</sc>‐fucopyranoside and dodecyl 3, 4‐di‐<italic>O</italic>‐acetyl‐<italic>α</italic>‐<sc>L</sc>‐rhamnopyranosyl‐(1→2)‐4‐<italic>O</italic>‐acetyl‐<italic>β</italic>‐<sc>D</sc>‐fucopyranoside, respectively, by spectroscopic studies, including 2D‐NMR, and chemical transformations. In addition, undecyl, tridecyl, and tetradecyl homologs of <bold>1</bold> and <bold>2</bold>, named pelargosides A2–A4 and pelargosides B2–B4, were also characterized as minor constituents of the exudate.</p> </abstract>
