From the roots of Amsonia elliptica ROEM et SCHULT (Apocynaceae) collected at Saitama and Mie Prefectures, several indole alkaloids were isolated, including tetrahydrosecamine (Ib), pleiocarpamine (III), yohimbine (IV), β-yohimbine (V), and antirhine (VI). From the same plant, new indole alkaloids, antirhine methochloride (VII), 3, 4, 5, 6-tetradehydro-β-yohimbinium chloride (VIII), and 10-hydroxygeissoschizol (IX) were isolated and characterized by chemical means.
