is a "super-food" and has attracted researchers' attention due to its anti-inflammatory, antioxidant, and analgesic properties. Herein, we investigated the antinociceptive effects of in different rodent behavior models of inflammatory pain. Male Swiss mice were treated with (3-300 mg/kg, p.o.), indomethacin (10 mg/kg, p.o.), or vehicle (0.9% NaCl 10 mL/kg). Behavioral tests were performed with administration of acetic acid (0.6%, i.p.), formalin 2.7% (formaldehyde 1%, i.pl.), menthol (1.2 µmol/paw, i.pl.), cinnamaldehyde (10 nmol/paw, i.pl.), capsaicin (1.6 µg/paw, i.pl.), glutamate (20 µmol/paw, i.pl.), or naloxone (1 mg/kg, i.p.). The animals were also exposed to the rotarod and open field test to determine possible effects of on locomotion and motor coordination. The quantitative phytochemical assays exhibited that contains significant concentrations of total phenols and flavonoid contents, as well as it showed a powerful antioxidant effect with the highest scavenging activity. Oral administration of completely inhibited the abdominal contortions induced by acetic acid (ED = 20.51 mg/kg). treatment showed significant inhibition of formalin-induced nociceptive behavior during the inflammatory phase, and the opioid-selective antagonist markedly blocked this effect. Furthermore, our data indicate that the mechanisms underlying analgesia appear to be related to its ability to modulate TRMP8 and TRPA1, but not by TRPV1 or glutamatergic system. represents an orally active and safe natural analgesic that exhibits great therapeutic potential for managing inflammatory pain disorders.
是一种“超级食物”,因其具有抗炎、抗氧化和镇痛特性而引起了研究人员的关注。在此,我们研究了 在不同的炎性疼痛啮齿动物行为模型中的镇痛作用。雄性瑞士小鼠用 (3-300 mg/kg,po)、吲哚美辛(10 mg/kg,po)或载体(0.9%NaCl 10 mL/kg)处理。在给予醋酸(0.6%,ip)、甲醛 2.7%(甲醛 1%,ipl)、薄荷醇(1.2 µmol/爪,ipl)、肉桂醛(10 nmol/爪,ipl)、辣椒素(1.6 µg/爪,ipl)、谷氨酸(20 µmol/爪,ipl)或纳洛酮(1 mg/kg,ip)后进行行为测试。还对动物进行了旋转棒和旷场测试,以确定 在运动和运动协调方面可能产生的影响。定量植物化学分析表明, 含有高浓度的总酚类和类黄酮含量,并且具有强大的抗氧化作用,具有最高的清除活性。口服 完全抑制了醋酸引起的腹部扭曲(ED = 20.51 mg/kg)。 处理显示出对福尔马林诱导的疼痛行为的显著抑制作用,而阿片受体选择性拮抗剂显著阻断了这种作用。此外,我们的数据表明, 镇痛的机制似乎与其调节 TRMP8 和 TRPA1 的能力有关,而不是与 TRPV1 或谷氨酰胺能系统有关。 代表一种口服活性和安全的天然镇痛药,具有治疗炎性疼痛障碍的巨大治疗潜力。
