Mass spectrometric study on plant glycosides molecular complexation with streptocid (sulfanylamide)

Molecular complexation of streptocid (sulfanylamide) with 3- O -α-L-rhamnopyranosyl-(1 → 2)- O -α-L-arabinopyranoside of hederagenin (α-hederin) and its 28- O -α-L-rhamnopyranosyl -(1 → 4)- O -β-D-glucopyranosyl-(1 → 6)- O -β-D-glucopyranosyl ester (hedera saponin C) has been studied with electrospr...

Description
Summary:Molecular complexation of streptocid (sulfanylamide) with 3- O -α-L-rhamnopyranosyl-(1 → 2)- O -α-L-arabinopyranoside of hederagenin (α-hederin) and its 28- O -α-L-rhamnopyranosyl -(1 → 4)- O -β-D-glucopyranosyl-(1 → 6)- O -β-D-glucopyranosyl ester (hedera saponin C) has been studied with electrospray ionization mass spectrometry for the first time. It was established that α-hederin forms a 1: 1 complex with streptocid. Hedera saponin C complexes with streptocid with the molar ratio 1: 1, 2: 1, and 2: 2 were more stable. Conclusions were drawn about the influence of the glycosides and streptocid structure on complexation.
