Phytochemical and Biological Investigations on Cephalaria anatolica

“…The structures of the new triterpene glycosides were determined as 3-O-β-D-glucopyranosyl- (2). The known compounds were identified as davisianoside A (3), davisianoside B (4) [15], elmalienoside A (5), elmalienoside B (6) [8], macranthoside A (7) [16], macranthodin A (8), macranthodin B (9) [17], akebia saponin D (10), dipsacoside B (11) [18], 3-O-β-D-glucopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-Larabinopyranosyl hederagenin 28-O-β-D-glycopyranosyl ester (12) [19] and aristatoside A (13) [10]. The structures of these compounds were identified by chemical methods including acidic and alkaline hydrolysis, silylation and extensive spectroscopic analysis, along with 1D, 2D NMR and HRESIMS data.…”
