Colchicum ritchii of Jordanian origin has yielded the diphenolic phenethyltetrahydroisoquinoline (-)-isoautumnaline [2], which is the first naturally occurring analog of the known (-)-autumnaline [1]. The absolute configuration of both alkaloids was established through a study of their cd spectra. Two new colchicine-type alkaloids are (-)-specioritchine [5] and its structural isomer (-)-speciocolchine [6]. Androcymbine, which was previously known only in the levorotatory form, has now been found as the dextrorotatory enantiomer [7]. It is accompanied in the plant by the related base (+)-colchiritchine [8]. Initial investigations on Colchicum ritchii R. Br. (Liliaceae) had revealed the presence of (-)-colchicine [3], (-)-N-formyldeacetylcolchicine, (-)-demecolcine, (-)-colchiceine, and a compound believed to be either (-)-2- or (-)-3-demethylcolchicine (1-3). Presently, we were able to collect this plant in southern Jordan, and the study of its alkaloidal content yielded a variety of alkaloids belonging to the autumnaline [1], colchicine [3], and androcymbine [4] series.
