Abstract
From the aerial parts of Asperula arvensis L. 9 known flavonol glycosides, namely quercetin (1), isoquercitrin [= quercetin 3-O-\beta-glucopyranoside] (2), hyperin [= quercetin 3-O-\beta -galactopyranoside] (3), quercetin 7-O-\beta-galactopyranoside (4), quercetin 4'-O-\beta-galactopyranoside (5), isorhamnetin 3-O-\beta -galactopyranoside (6), isorhamnetin 5-O-\beta-galactopyranoside (7), dihydrokaempferol 7-4'-dimethylether 3-O-\beta -glucopyranoside (8) and isorhamnetin 3-O-\alpha -rhamnopyranosyl (1''' \to 6'')-\beta -glucopyranosid (9), were isolated. The structures of the compounds were elucidated by high field 1D and 2D NMR and ESI-MS spectroscopies.
