    Benzylbenzoate and norlignan glucosides from Curculigo pilosa: structural analysis and in vitro vascular activity[Pubmed: 11140602 ]

    METHODS AND RESULTS:
    From the rhizomes of Curculigo pilosa, two benzylbenzoate diglucosides, piloside A and piloside B, and a glucosyl-fused norlignan, Pilosidine, previously obtained only as the tetra-O-methyl derivative, were isolated.
    CONCLUSIONS:
    Pilosidine showed facilitating effect on adrenaline evoked contractions in rabbit aorta isolated preparations.

    Studies on vasoconstrictor activity of Curculigo pilosa extracts and of its isolated compounds.[Pubmed: 11482757]

    METHODS AND RESULTS:
    The Curculigo pilosa total extract, its butanolic fraction (0.5 microg-100 mg/kg) and the most active in vitro compound structurally similar to adrenaline, Pilosidine (10 ng-l mg/kg), caused a reversible and dose-dependent increase in blood pressure in anaesthetized rat. This hypertensive effect is partially reversed (90%) by the prior administration of phentolamine (1 mg/kg) and abolished by pre-treatment with phentolamine (1 mg/kg) and atenolol (100 microg/kg). Neither tachiphylaxis nor any toxic effects were observed.
    CONCLUSIONS:
    These experimental findings suggest an interaction between C. pilosa and the peripheral adrenergic system (particularly with alpha1 and beta1 receptors); the structure of the bioactive glucosides could be important in evoking this effect.
