title: Violarvensin, a new flavone di-C-glycoside from Viola arvensis.
abstract: A new flavonoid di-C-glycoside, violarvensin (1), was isolated from the aerial parts of Viola arvensis, together with the known derivative violanthin (2). The structure of 1 was established as apigenin-6-C-beta-D-glucopyranosyl-8-C-beta-D-6-deoxygulopyrano side by spectral analysis.
