Narcissus incomparabilis

Oxidation of Pluviine (276), isolated from Narcissus pseudonarcissus. Narcissus incomparabilis, and Lycoris radiata Herb., with benzophenone and potassium rerr-butylate yielded a red phenol-betaine 277 from which one neutral covalent form can be drawn (Scheme 90). The betaine has absorption maxima Imax (loge) in a buffer at pH 10 at 240 (4.49), 325 (4.46), 360 (3.58), 380 (3.27), and 490 (3.26) nm. In dilute HCl, a salt is formed [lmax = 260 (4.57), 295 (4.39), 340 (3.76), 355 (3.84), 400 (3.62) nm] (57CB363). The oxidation of the alkaloid Caranine gives a similar betaine, the 1,3-dioxolo derivative 278 (56CIL348). [Pg.142]

This alkaloid has been isolated from the bulbs of I/ycoris radiata (87) and from several garden varieties of Narcissus pseudonarcissus and N. incomparabilis (90, 90a). The base, C17H21NOJ, contains one reducible double bond, one hydroxyl, and two methoxyls. [Pg.327]
