Photophysical Chracterization of Galanthus elwesii Hook

Revised NMR data for incartine: an alkaloid from Galanthus elwesii.

Phytochemical studies on Galanthus elwesii resulted in the isolation of five alkaloids: incartine, hordenine, hippeastrine, 8-O-demethylhomolycorine and lycorine. The NMR data given previously for incartine were revised and completed by two-dimensional 1H-1H and 1H-13C chemical shift correlation experiments. In vitro studies on the bioactivity of incartine were carried out.

Quantitative Determinations on Galanthus Rizehensis

Galanthus rizehensis Stern (Amaryllidaceae) was collected from Maçka, Trabzon during flowering and fruiting seasons. Quality control studies and quantitative determination of lycorine were carried out on the prepared specimens. In this respect, assays for humidity, total ash, sulphated ash, hydrochloric acid-insoluble ash were performed on each drug specimen. The total alkaloidal content of G. ...

The first phytochemical report of Galanthus transcaucasicus Fomin

UNLABELLED BACKGROUND AND THE PURPOSE OF STUDY: Galanthus transcaucasicus Fomin (Amaryllidaceae) is an endemic species to the Caucasia and Alborz mountains in Iran which locally named "Gole-Barfi". While there are many reports on pharmacological activities of Galanthus species' alkaloids, there is no report on G. transcaucasicus and this article is the first phytochemical study on this species....
