helleborus niger/glycoside

Phytochemical investigation of Helleborus niger L. (Ranunculaceae) leaf methanol extract allowed to isolate a phenolic glucoside derivative and two flavonoid glycosides characterized as phenyllactic acid 2-O-β-D-glucopyranoside (1), quercetin 3-O-2-(E-caffeoyl)-α-L-arabinopyranosyl-(1 →

Morphological changes and phenolic patterns of developing hellebore sepals and the effects of pistil removal on these parameters were studied by comparing six flower stages of Helleborus niger. Color changes were evaluated colorimetrically, chlorophyll content was measured spectrophotometrically,

BACKGROUND Helleborus niger L (Ranunculaceae) is used Ayurvedic and Unani systems and other herbal medicine systems. The roots of H. niger have a good medicinal value. OBJECTIVE To conduct a pharmacognostical and phytochemical study of H. niger. METHODS The pharmacognostical studies on roots

Steroidal saponins comprise a substantial part of the secondary metabolite spectrum in the medicinal plant Helleborus niger L. (black hellebore). The saponin fraction from the roots was investigated by LC-MS(n) resulting in 38 saponins and β-ecdysone. Nine diosgenyl-type glycosides, mainly

Ethnopharmacological relevance: Ethnopharmacological data and ancient texts support the use of black hellebore (Helleborus odorus subsp. cyclophyllus, Ranunculaceae) for the management and treatment of epilepsy in ancient Greece.
