title: The alkaloids of Strychnos dolichothyrsa.
abstract: In the stem bark of Strychnos dolichothyrsa Gilg ex Onochie et Hepper (Loganiaceae) the following alkaloids were found: bisnor-dihydrotoxiferine, bisnor-C-curarine, bisnor-dihydrotoxiferine N-oxide and bisnor-dihydrotoxiferine di-N-oxide. Tentatively, two alkaloids were identified as bisnor-C-alkaloid D and 18-deoxy Wieland-Gumlich aldehyde. Bisnor-dihydrotoxiferine seems to give dichlorometho compounds and N-oxides easily, analogous with strychnine and brucine.
