title: Indole Alkaloids from Hunteria zeylanica.
abstract: Six new bisindole alkaloids, hunterizeylines A-F (1-6), three new monomers, hunterizeylines G-I (7-9), and 13 known alkaloids were isolated from an aqueous MeOH extract of the twigs and leaves of Hunteria zeylanica. Hunterizeyline H, geissoschizol, and dihydrocorynantheol displayed weak insecticidal activity against the aphid Rhodobium porosum, with IC50values of 168.2, 360.5, and 290.6 μM, respectively.
