title: Teucrol, a decarboxyrosmarinic acid and its 4'-O-triglycoside, teucroside from Teucrium pilosum.
abstract: Teucrol, a decarboxy rosmarinic acid and its triglycoside, teucroside, 9'-decarboxyrosmarinic acid-4'-O-alpha-rhamnosyl-(1'''-->6''')-O-beta-galactosyl-(1'''-->4'')-O-alpha-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.
