ALKALOIDS OF ZEPHYRANTHES FLAVA

From fresh, mature seeds of Zephyranthes flava, two new 2-oxyphenanthridinium alkaloids, zefbetaine and zeflabetaine along with 15 known free and glucosyloxy alkaloids have been isolated by gradient solvent extraction, chromatography and derivatization.The new compounds have been characterized by comprehensive spectroscopic analyses, chemical transformations and synthesis.Additionally, changes in the major alkaloids during development of the fruits have been analysed and their biological significance appraised.

OCCURRENCE OF TWO EPIMERIC ALKALOIDS AND METABOLISM COMPARED WITH LYCORINE IN CRINUM LATIFOLIUM

Two new epimeric pyrrolophenanthridine alkaloids, 2-epilyocorine and 2-epipancrassidine, were isolated from the flower-stem fluid of Crinum latifolium.The structures of the two alkaloids were established by spectroscopic analyses, crucial chemical transformation, and synthesis in case of the former.The differences in the metabolic pathways of lycorine and 2-epilycorine were studied under simulated physiological conditions and their biochemical significance was appraised.Key Word Index - Crinum latifolium; Amaryllidaceae; epimeric alkaloids; 2-epilycorine; 2-epipancrassidine, metabolic pathways; biochemical significance.
