Parvisoflavanone may have α-Glucosidase inhibitory activity.

Three new isoflavanones (1-3) and thirteen known compounds (4-16) were isolated from the roots of Mucuna pruriens. METHODS AND RESULTS: The absolute configurations of isoflavanones 1-3 and Parvisoflavanone (4), lespedeol C (5), and uncinanone C (6) were addressed by a circular dichroism technique. Isoflavanones, isoflavones, and pterocarpans of M. pruriens were found to be α-glucosidase inhibitors. Medicarpin (7) and parvisoflavone B (9) were potent α-glucosidase inhibitors (twofold less active than the standard drug acarbose). CONCLUSIONS: The production of bioactive metabolites in M. pruriens seems to be season-dependent.
