摘要：

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. (C) 2000 Elsevier Science Ltd.
