Antineoplastic Agents, 162. Zephyranthes candida

Journal of Natural Products, 1990
The 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, 1985
Abstract 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 ...

(+)-Epimaritidine, an alkaloid from Zephyranthes rosea

Phytochemistry, 1985
Abstract 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 ...
