Zusammenfassung:	Teucrol, a decarboxy rosmarinic acid and its triglycoside, teucroside, 9′-decarboxyrosmarinic acid-4′- O-α-rhamnosyl-(1‴→6‴)- O-β-galactosyl-(1‴→4″)- O-α-rhamnoside, are two new natural phenolics which have been isolated and identified from the aqueous alcohol extract of the whole plant of Teucrium pilosum (Decne) Asch. & Schweinf. (Lamiaceae). Structures were determined by conventional methods of analysis and confirmed by MS and NMR spectral analysis, including 2D-homonuclear COSY experiment.
