Özet

Two cyclic natural compounds, 3β-O-[α-L-rhamnopyranosyl- (1→2)-β-D-glucopyranosyl]-13α,14α-epoxy-8α,12β, 15-trihydroxy-(17E,21E)-17,21-campanuldien-6′ (30)-olide, called lactifloroside A, 1, and 3β-O-[β-D-glucopyranosyl-(1→2)-β-D- glucopyranosyl]-13α,14α-epoxy-8α,12β-dihydroxy-(17E,21E) -17,21-campanuldien-6′ (30)-olide, called lactifloroside B, 2, were isolated for the first time from Campanula lactiflora and their structures deduced by high field 1D and 2D 400 MHz NMR, FT-IR, HPLC, GC-MS, (+/-) LC-MS/MS and (+) FAB-MS spectra. The aglycones of the 2 saponins were named 13α,14α-epoxy-3β,8α,12β,15-tetrahydroxy-(17E,21E) -17,21-campanuldien-30-oic acid and 13α,14α-epoxy-3β,8α, 12β-trihydroxy-(17E,21E)-17,21-campanuldien-30-oic acid, and designated as campanuloic acid and 15-deoxycampanuloic acid, respectively. © TÜBİTAK.
