    Flavonol and secoiridoid glycosides from Coutoubea spicata.[Reference: WebLink]

    CONCLUSIONS:
    Two flavonol glycosides, unusual for the Gentianaceae, Clovin and the new quercetin 3-O-rhamnosyl-(1 → 6)-(4″-trans-p-coumaroyl)galactoside 7-O-rhamnoside (4″-trans-p-coumaroylClovin) have been isolated from the aerial parts of Coutoubea spicata.
    CONCLUSIONS:
    The bitter principles of C.spicata were identified as gentiopicrin and swertiamarin. Minor polyphenolic glycosides were characterized by high pressure liquid chromatography with photodiode array detection (HPLC-UV/Vis).
