Quantitative Determinations on Galanthus Rizehensis
نویسندگان
چکیده
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. rizehensis was determined by a titrimetric method. Furthermore, the identification and quantitative determination of lycorine on the aerial and underground parts of the plant collected during two different seasons were performed by using a HPLC-DAD method.

GC-MS investigation and acetylcholinesterase inhibitory activity of Galanthus rizehensis.
GC-MS (gas chromatography-mass spectrometry) analyses of alkaloids in the aerial parts and bulbs of Galanthus rizehensis Stern (Amaryllidaceae), collected during two different vegetation periods, was performed. Twenty three alkaloids were identified in four different alkaloid extracts. Acetylcholinesterase (AChE) inhibitory activities of the alkaloid extracts were tested. Both the highest alkal...
متن کاملRevised 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.

To optimize conditions for micropropagating Galanthus transcaucasicus Fomin, the effect of explant type, different concentrations of sucrose, type and different concentrations of auxin were examined on bulblet production. For the induction of bulblets, three types of bulb scales were usesd as explants. A two-step sterilization procedure was applied. Assessments were made after incubation for 20...

Background and objectives: Many members of the Amaryllidaceae are regarded as toxic. The toxic constituents that occur in the whole family are referred to as the Amaryllidaceae alkaloids. The main aim of this study was the identification of alkaloid compounds from Galanthus transcaucasicus Fomin, a medicinal plant from Amaryllidaceae. Methods: Planar and column chromatography techniques were us...
