Scoparinol, a diterpene, isolated from Scoparia dulcis showed significant a
nalgesic (p < 0.001) and anti-inflammatory activity (p < 0.01) in animals.
A sedative action of scoparinol was demonstrated by a marked potentiation o
f pentobarbital-induced sedation with a significant effect on both onset an
d duration of sleep (p < 0.05). Measurement of urine volurne after administ
ration of scoparinol indicated its significant diuretic action.
