title: Organ-to-organ and seasonal variation in alkaloids from Crinum macowanii.
abstract: The distribution and seasonal variation of alkaloids from Crinum macowanii were investigated. The alkaloids lycorine, 1-O-acetyllycorine, crinine, powelline, crinamine, crinamidine, 3-O-acetylhamayne, 1-epideacetylbowdensine and cherylline were isolated from this plant using gas chromatography. Significant organ-to-organ variations were detected for the alkaloids crinine, lycorine, powelline, crinamidine, 3-O-acetylhamayne and crinamine. Crinine, crinamidine and 1-epideacetylbowdensine showed significant seasonal variation.
