ABSTRACT
Objective: To study the constituents from the roots of Paeonia lactiflora. Methods: The chemical constituents were isolated by various chromatographic techniques and their structures were elucidated by physicochemical properties and NMR data. Results: Eleven compounds were obtained and characterized as (4S)-perillic acid 6-O-α-L-arabinopyranosyl-(1'→6'')- β-D-glucopyranosyl (1), 4,9-dihydroxy-8,10-dehydrothymol-1-O-β-D-glucoside (2), emodin-8-O-β-D-glucoside (3), resveratrol (4), β-D-glucopyranosyl benzoate (5), ilexperphenoside A (6), catechol (7), methyl gallate (8), ethyl gallate (9), 3-methoxygallic acid (10), 1,2,3,4,6-penta-O-galloyl-β-D-glucopyranoside (11). Conclusion: Compound 1 is identified as a new compound, named perillic acid glycoside, compounds 2 and 5 are identified from the genus Paeonia for the first time.
