Two new alcohol glycosides from the roots of Paeonia intermedia C. A. Meyer.
Two new alcohol glycosides, 1-O-β-d-glucopyranosyl-deoxypaeonisuffrone (1) and 9-O-β-d-apiofuranoyl-(1→6)-β-d-glucopyranosyl-xanthoarnol (2), together with eight known compounds (3-10), have been isolated from the dried roots of Paeonia intermedia C. A. Meyer. Their structures were mainly elucidated on the basis of ESIMS, one- and two-dimensional NMR techniques. Antibacterial activities of compounds 1-10 were evaluated, and compounds 9 and 10 showed antibacterial activities against Staphylococcus argenteus CMCC26003 and Escherichia coli CMCC44103.
