ALKALOIDS FROM DACTYLICAPNOS-TORULOSA

Four new alkaloids named isoapocavidine, torulosine, torulosinine and oxocoryrutine were isolated from whole plants of Dactylicapnos torulos a. The structures were elucidated by spectral studies including UV, MS , H-1, C-13 NMR, C-13-H-1 COSY and C-13-H-1 COLOC. Known alkaloids iso lated from this plant are 8-acetonyl-dihydrosanguinarine, norsanguinar ine, oxosanguinarine, (+/-)-alpha-hydrastine, (+/-)-apocavidine, (+/-) -adlumidine, (+/-)-bicuculline, (+/-)-cheilanthifoline, (+/-)-beta-hyd rastine, (+/-)-demethylcorydalmine, protopine, fumaridine, 1-methoxybe rberinium chloride, N-trans-feruloyltyramine, N-methylhydrasteine meth yl ester, N-methylhydrasteine hydroxy lactam, N-methylhydrasteine and hunnemanine. The C-13 NMR data for some of the known compounds are giv en for the first time.
