Gentiana asclepiadea and Bees

Chemical composition, antioxidant and antigenotoxic activities of different fractions of Gentiana asclepiadea L. roots extract.

The aim of this study was to evaluate the antioxidant and antigenotoxic activities of chloroform, ethyl acetate and n-butanol fractions obtained from Gentiana asclepiadea L. roots methanolic extract. The main secondary metabolites sweroside, swertiamarin and gentiopicrine were quantified in G. asclepiadea root extracts using HPLC-DAD analysis. Amount of total phenols, flavonoids, flavonols and ...

PROTECTIVE ROLE OF METHANOL EXTRACTS OF Gentiana asclepiadea L. AND G. cruciata L. AGAINST GENOTOXIC DAMAGE INDUCED BY ETHYL METHANESULFONATE

Virus Infections in Gentiana Species

Gentiana species generally are of little importance to horticulture. This may explain that little attention has been given to virus infections in these ornamentals, so far. However, during the last couple of years the number of samples for virus diagnosis increased. The main symptoms recorded, were growth reduction, necrotic lesions and decline. The virus isolated most frequently was broad bean...

Studies on the constituents of Gentiana species. II. A new triterpenoid, and (S)-(+)- and (R)-(-)-gentiolactones from Gentiana lutea.

A new triterpenoid, 12-ursene-3beta, 11alpha-diol 3-O-palmitate (1), has been isolated from the rhizomes and roots of Gentiana lutea, together with the artificial diene derivative, 9 (11), 12-ursadien-3beta-ol 3-O-palmitate (1a) and five known compounds (3-7). Their structures were established on the basis of spectral analysis. In addition, (+/-)-gentiolactone [(+/-)-2], isolated from this plan...

Scientific Study of Gentiana kurroo Royle

The present investigation was carried out to review and highlight the potential phytochemicals and medicinal phenomena of the critically endangered medicinal plant, Gentiana kurroo Royle of the western and north-western Himalayas. The medicinal plant is heavily exploited for root and rhizome. Due to its endemic nature and the high rate of exploitation from its natural habitat, this species had ...
