Baker (Asteraceae) has high economic value from Chapada to Araripe and its bark essential oil is a potential source of alpha-bisabolol. The present study aimed to elucidate the antinociceptive and antipruritic properties of the essential oil of Baker (EOVA) in mice.
The antinociceptive activity was assessed using the capsaicin, glutamate, hot plate and cold allodynia tests. The antipuritic effects were also verified based on histamine-induced scratching behavior.
EOVA reduced the paw licking induced by capsaicin, but not that induced by glutamate. The essential oil increased the latency time in the hot plate, attenuated the cold allodynia induced by acetone and inhibited histamine-induced scratching behavior.
The experimental data demonstrated that EOVA showed central and peripheral antinociceptive activity and antipruritic effect.
贝克氏菊(菊科)从查帕达到阿拉里皮具有很高的经济价值,其树皮精油是α-红没药醇的潜在来源。本研究旨在阐明贝克氏菊精油(EOVA)对小鼠的抗伤害感受和止痒特性。
使用辣椒素、谷氨酸、热板和冷痛觉过敏试验评估抗伤害感受活性。还基于组胺诱导的抓挠行为验证了止痒效果。
EOVA减少了辣椒素诱导的舔爪行为,但未减少谷氨酸诱导的舔爪行为。该精油增加了热板试验中的潜伏期,减轻了丙酮诱导的冷痛觉过敏,并抑制了组胺诱导的抓挠行为。
实验数据表明,EOVA具有中枢和外周抗伤害感受活性以及止痒作用。
