Undescribed Amaryllidaceae Alkaloids from <i>Zephyranthes citrina</i> and Their Cytotoxicity. [PDF]
J Nat ProdThis phytochemical study presents the isolation of eight alkaloids from Zephyranthes citrina Baker. The structures of the new alkaloids, zephycitrine (1) and 6-oxonarcissidine (2), were established by analysis of spectroscopic and spectrometric data. Processing the EtOH extract under acid-base conditions yielded the unreported isolation artifacts 3 and
