Two alkaloids from Zephyranthes carinata
Phytochemistry, 1998Abstract Two new Amaryllidaceae alkaloids, 1- O -(3-hydroxybutyryl) pancratistanin and 1-O-(3-O-β- d -glucopyranosylbutyryl) pancratistatin, were isolated from the bulbs of Zephyranthes carinata . The structures of the two alkaloids were established by comprehensive spectral analysis.

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

APOMIXIS IN ZEPHYRANTHES TEXANA HERB.
American Journal of Botany, 1951ZEPHYRANTHES TEXANA Herb. is a species of the subtribe Zephyranthinae of the Amaryllidaceae. In its range it is restricted to the southeastern quarter of Texas where it is known as a yellow rain-lily. It is the same species in which Pace (1913) reported apomixis. At that time it was called Atamosco texana but Zephyranthes Herb.

Two new ceramides from Zephyranthes candida
Chemistry of Natural Compounds, 2009Two new ceramides were isolated from the bulbs of Zephyranthes candida. Their structures were established as (2S,3S,4R,13E)-1,3,4-trihydroxy-2-[(2′R)-2′-hydroxytetracosanoylamino]-13-octadecene, named zephyranamide A (1) and (2S,3S,4R)-1,3,4-trihydroxy-2-octacosanoylaminohexadecene, named zephyranamide B (2).

Distribution of Carbon 14 in Ovules of Zephyranthes drummondii
Botanical Gazette, 19541. Radioactive CO2 was fed to plants (Zephyranthes drummondii) which were producing flowering scapes. Subsequently, the ovaries were removed, and autoradiographs were prepared by two different methods. 2. The results indicate that readily soluble carbon-containing compounds are most concentrated in the vascular tissues, in a small area at the point of ...
