CRINUM; AN ENDLESS SOURCE OF BIOACTIVE PRINCIPLES: A REVIEW. PART III; CRINUM ALKALOIDS: BELLADINE-, GALANTHAMINE-, LYCORENINE-, TAZETTINE-TYPE ALKALOIDS AND OTHER MINOR TYPESAbstract
Crinums occupy an important position within plants of family Amaryllidaceae, and many of them have been broadly used in traditional and ethnomedicines throughout the world. Due to their richness in bioactive phytoconstituents, Crinums have been subjected to extensive chemical, cytological and pharmacological investigations that focused chiefly on their alkaloidal content. Continuing our appraisal about the results of phytochemical, biological and toxicological studies on Crinums and after considering lycorine- and crinine-alkaloids as the major classes in its two previous parts; the current part of our review work draws attention to members of the other less common alkaloidal classes as well as the new types that are not common in the family.
