Inhibitory actions of G. buchananii extract (2 g bark powder/100 ml Krebs) on pellet motility do not involve opioid or α-2 adrenergic receptor activation. A-B: Summary data showing that neither naloxone (10 μM; A, bracket with triangle) nor yohimbine (1μM; B, bracket with triangle) altered the ability of G. buchananii extract to reduce propulsive motility. The rebound prokinetic effect of G. buchananii extract detected after washout also persisted in the presence of naloxone and yohimbine (3 A-B, brackets with asterisks).
