title: Crinane and lycorane type alkaloids from Zephyranthes citrina.
abstract: Eight alkaloids have been isolated from Zephyranthes citrina (Amaryllidaceae). The alkaloid oxomaritidine is reported here for the first time from a natural source. The structure and stereochemistry of the alkaloids were determined by physical and spectroscopic methods.
