Lycoris

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]

In 1933, Schlubach and Knoop32 isolated a di-D-fructose dianhydride from Jerusalem artichoke and tentatively identified it as difructose anhydride I [a-D-Fru/-1,2 2,1 - 3-D-Fn / (5)]. Alliuminoside ( -D-fructofuranose- -D-fructofura-nose 2,6 6,2 -dianhydride) was isolated from tubers of Allium sewertzowi by Strepkov33 in 1958. Uchiyama34 has demonstrated the enzymic formation of a-D-Fru/-1,2 2,3 -(3-D-Fru/ [di-D-fructose anhydride III (6)] from inulin by a homogenate of the roots of Lycoris radiata Herbert. [Pg.213]

Long recognized as a family of their own, the amaryllids are now included in the Liliaceae by Cronquist but perhaps not generally. They are distributed throughout the world, mostly in the tropics and subtropics, and valued for their garden flowers (Amaryllis, Crinum, Lycoris, Narcissus, etc.). [Pg.13]

Forty-five samples representing 35 species were tested nine had been known to contain alkaloids Amaryllis belladonna, Ammo-charis coranica, Crinum asiaticum, C. giganleum, Haemanthus mul-liflorus, Hippeaslrum villatum, Lycoris radiata, Narcissus pseudonarcissus, Sprekelia formosissima. [Pg.13]

During the course of screening plants for insect antifeedants, the extract of the bulbs of Lycoris radiata Herb, was found to exhibit antifeeding activity when tested against the larvae of the yellow butterfly Eurema hecabe mandarina (61). [Pg.291]

Reinvestigation of the alkaloid extracts of Lycoris radiata Herb. (62) and Narcissus tazetta L. (68) has revealed that tazettine (397), which had been previously isolated from these plants, was an artifact of the isolation procedure, and pretazettine (395) was in fact the naturally occurring alkaloid. In view of... [Pg.326]

Nearly equal amounts of narciclasine and lycoricidine have been detected in Lycoris radiata Herb. (78). [Pg.88]

Independently, lycoricidine and lycoricidinol, two lactams which presented physical and chemical properties identical with those of margetine and narciclasine, respectively, were isolated from Lycoris radiata. A different interpretation of the physical and chemical data... [Pg.142]

Lycorine (69) was recognized as a potent emetic and a moderately toxic base from the time of its initial isolation from Narcissus pseudo narcissus L. (in about 1877) (48). Since that time its isolation from many other Amaryllidaceae, for example, Lycoris radiate Herb., has served to establish it as the most cosmopolitan alkaloid of the family. Typically, as much as 1% of the dry weight of daffodil bulbs may consist of lycorine (69), which has been reported to... [Pg.542]
