Original Paper


Caryopincaolide M (1), a new rearranged abietane diterpenoid with an unusual pent-4-enoic acid group on a 6/6/5 tricyclic ring system, and 7-epi-8-dehydroxypatriscabrol (3), a new iridoid, together with 17 known compounds, have been isolated from the whole plant of Caryopteris incana (Thunb.) Miq. Their structures were elucidated on the basis of 1-D and 2-D NMR, IR, and mass spectroscopic data. Compounds 1–5 were evaluated for their inhibitory activities against enzyme α-glucosidase, and the results showed that only 1 has moderate inhibitory activity against enzyme α-glucosidase with IC50 at 528.3 ± 12.37 mg/L.
