The study showed the antinociceptive and spasmolytic effects of J. spicigera ethanol extract in in vivo and/or in vitro assays. The extract had a regulatory effect on intestinal tissue motility and provided significant abdominal antinociceptive response in mice.
Justicia spicigera Schltdl. (Acanthaceae) is used for treatment of gastrointestinal illnesses therapy in traditional medicine. The objective of this study was to give evidence of the antinociceptive and spasmolytic effects of the J. spicigera ethanol extract (JS EtOH) using in in vivo and/or in vitro assays. The JS EtOH exerted regulatory effect on the motility and a partial relaxing response on the intestinal tissue. Furthermore, a significant abdominal antinociceptive response was obtained in mice, which was totally abolished in the presence of 5-HT1A receptor antagonist (WAY100635, 0.1 mg/kg, s.c.) and partially by blocking opioid receptors (NX, 1 mg/kg, i.p.), whereas the inhibition of the NO synthesis (L-NAME, 30 mg/kg, i.p.) facilitated antinociception of this extract. Kaempferitrin was isolated and identified as major secondary metabolite. These results support the analgesic and spasmolytic-like activity of J. spicigera aerial parts involving inhibitory neurotransmission reinforcing the potential of this medicinal plant for alleviating pain.
