—Colchicum ritchii of Jordanian origin has yielded the diphenolic phenethyl-tetrahydroisoquinoline (— )-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}. © 1987, American Chemical Society. All rights reserved.
