The total alkaloidal fraction of Albizia inopinata leaves (FLA) was investigated for its central nervous system (CNS) effects. FLA (10 mg/kg, i.p.) significantly reduced (45%) the locomotor activity in mice. In addition, it inhibited the conditioned avoidance response behavior and induced ptosis in rats. On the other hand, FLA did not exert significant(More)
Solanum asterophorum Mart. (Solanaceae) is a shrub popularly known as "jurubeba-defogo" in the northeast of Brazil. In the present work, the methanol extract (SA-MeOH, 3750 microg/mL) and isojuripidine (10(-7) - 3 x 10(-4) M), a steroidal alkaloid obtained from S. asterophorum Mart. leaves, inhibited phasic contractions induced by both 1 microM histamine(More)
