Another two novel ceramides from Zephyranthes candida
Chemistry of Natural Compounds, 2010From the the bulbs of Zephyranthes candida (Amaryllidaceae), another two novel ceramides have been isolated and identified. The structures of the two novel compounds were established as (2S,3S,4R,21E,2′R)2-[N-(2′-hydroxynonadecanoyl)-N-(1′′,2′′-dihydroxyethyl)amino]-21-hexacosene-1,3,4-triol, named zephyranamide C (1), and 1,3,4,5,6-pentahydroxy-2-(2 ...

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.

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 ...

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

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.

Phosphatidylpyrrolophenanthridine alkaloids from Zephyranthes flava
Phytochemistry, 1987Abstract Four new alkaloidal phospholipids, 2-O-glycerophosphoryllycorine, phosphatidyllycorines, phosphatidylpseudolycorines and phosphatidyllycorinium methocation, were isolated from the flowers of Zephyranthes flava. The structures of these compounds were established by comprehensive spectral analyses, chemical transformations and synthesis, where
