Abstract: Objective: To isolate and identify monoterpene glucosides from the seed cake of Paeonia rockii. Methods: Monoterpene glucosides were isolated and purified by successive column chromatographies on silica gel and Sephadex LH-20 and semi-preparative high performance liquid chromatography (semi-pre-HPLC). Spectroscopic methods were used to elucidate their structure. Results: Eight monoterpene glucosides were isolated from the seed cake of Paeonia rockii. They were identified as β-gentiobiosylpaeoniflorin (1), abiflofin (2), oxyalbiflorin (3), 1-O-β-D-glucopyransoyl-paeonisuffron (4), abiflofin R1 (5), paeonifanin (6), 8-O-debenzoyl-albiflorin (7), and mudanpioside F (8). Conclusions: All of these compounds were isolated from the seed cake of P. rockii for the first time in this study. These compounds and their derivatives were of significant interest for drug research and development. The study may provide important evidence supporting the exploitation of the seed cake of P. rockii.
