title: 2-O-(3-Hydroxyhexadecanoyl)glycerol and 2-O-(3-hydroxytetradecanoyl)glycerol and their 1-O-acetyl derivatives from the glandular trichome exudate of Verbascum blattaria f. erubescens.
abstract: Chemical investigation of the glandular trichome exudate of Verbascum blattaria f. erubescens (Scrophulariaceae) led to the isolation of four new glycerides, 1-O-acetyl-2-O-[(R)-3-hydroxytetradecanoyl]-sn-glycerol, 1-O-acetyl-2-O-[(R)-3-hydroxyhexadecanoyl]-sn-glycerol, 2-O-[(R)-3-hydroxytetradecanoyl]glycerol and 2-O-[(R)-3-hydroxyhexadecanoyl]glycerol. Their structures, including the configurations at the stereogenic centres, were elucidated from spectral evidence and chemical transformations.
