Abstract
Two new nor-lignans, pulvin A (1) and moellenoside C (2), along with two known compounds (3–4) were isolated from the whole plant of Selaginella pulvinate (Hook. & Grev.) Maxim. The structures of the new compounds were established on the basis of spectroscopic data and acid hydrolysis. All the isolates were investigated for their antihyperglycemic activities in 3T3-L1 adipocytes. The results showed that compounds 1 and 2 promoted the glucose consumption prominently in 3T3-L1 adipocytes in a dose-response manner. Compound 1 and 2 induced 1.14–1.73 folds and 1.03–1.55 folds changes relative to the basal level, respectively, in the concentration range of 12.5 μM to 50 μM.
