The following alkaloids have been isolated from the epigeal part of Sophora alopecuroides in the flowering phase: sophoridine (0.06%), sophoramine (0.036%), sophocarpine (0.051%), aloperine (0.03%), a liquid base C19H23NO3 (0.00057%), and a new base C15H20N2O (0.0025%) which we have called neosophoramine and for which the structure of the A/B and B/C-cis, A/C-trans isomer of sophoramine is proposed. © 1976, Plemum Publishing Corporation.
