Alkaloids of zephyranthes flava
Phytochemistry, 1986Abstract 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.

Antineoplastic Agents, 162. Zephyranthes candida
Journal of Natural Products, 1990The Chinese medicinal plant Zephyranthes candida was found to contain a cytostatic constituent. Separation of a n-BuOH extract directed by results of a bioassay employing the P-388 lymphocytic leukemia led to trans-dihydronarciclasine [2] as the principal cytostatic agent with ED50 3.2 X 10(-3) micrograms/ml.

ZEPHYRANTHES GRACILIS HERB. AND ZEPHYRANTHES MINIMA HERB.
American Journal of Botany, 1943PROBABLY NOT in the entire field of botanical taxonomy and plant nomenclature is greater confusion to be found than now exists around the plants represented by the names Zephyranthes gracilis Herb., Z. minima Herb., Z. Hieronymi Pax and Amaryllis parvula Seub. Several attempts have been made to straighten out the identity of these plants but so far the

Flavans from Zephyranthes flava
Phytochemistry, 1985Abstract A new optically active flavan aglucone, 7-hydroxy-3′,4′-methylenedioxyflavan, and its 7-glucoside have been isolated from the bulbs of Zephyranthes flava , collected at flowering. Additionally, two known flavans, 7,4′-dihydroxy-3′-methoxyflavan and 7-methoxy-2′-hydroxy-4′,5′-methylenedioxyflavan, have been isolated for the first time from ...

The Breeding System of Zephyranthes atamasco (Amaryllidaceae)
Bulletin of the Torrey Botanical Club, 1991mean ? standard deviation) as those from cross-pollinations (24.7 ? 14.0). Germination was slightly lower for seeds produced from self-pollinations (62.3 ? 36.1%) as compared with seeds from cross-pollinations (77.7 ? 22.9%). Self- and cross-pollinations resulted in fruits with significantly more seeds than open-pollinations (13.4 ? 7.3).

(+)-Epimaritidine, an alkaloid from Zephyranthes rosea
Phytochemistry, 1985Abstract The isolation and determination, by spectroscopic analyses and chemical correlation, of the structure and stereochemistry of (+)-epimaritidine, a new alkaloid from Zephyranthes rosea , is reported. A facile transformation of maritidine to (+)-epimaritidine is described and the mechanism is appraised in the light of the thermodynamic ...

Four new Amaryllidaceae alkaloids from Zephyranthes candida
Journal of Natural Medicines, 2014Four new Amaryllidaceae alkaloids (1-4) possessing a homolycorine-type or a crinine-type skeleton have been isolated from the aerial part of Zephyranthes candida, and their structures were elucidated on the basis of spectroscopic data. The stereochemistry was elucidated by combination of NOESY correlations and CD analyses.
