Analgesic, diuretic, and anti-inflammatory principle from Scoparia dulcis

Scoparinol, a diterpene, isolated from Scoparia dulcis showed significant analgesic (p < 0.001) and anti-inflammatory activity (p < 0.01) in Animals. A sedative action of scoparinol was demonstrated by a marked potentiation of pentobarbital-induced sedation with a significant effect on both onset and duration of sleep (p < 0.05). Measurement of urine volume after administration of scoparinol indicated its significant diuretic action.
