摘要: 为研究白簕[Acanthopanax trifoliatus (L.) Merr]根皮乙酸乙酯部位(BLE)镇痛抗炎及抗氧化能力,以BLE为研究对象,采用热板致痛法、醋酸扭体法、二甲苯致小鼠耳肿胀法、角叉菜胶致小鼠足肿胀法及前列腺素E2(PGE2)炎症介质含量测定探讨其镇痛、抗炎作用,通过DPPH法和ABTS法评价BLE的抗氧化能力。结果表明,与空白组相比,BLE溶液各剂量组给药60 min时痛阈值均显著或极显著提高,与给药前相比,各剂量组在各时间点痛域值均显著或极显著提高,各剂量组与雷公藤多苷片组间无显著性差异。与空白组相比,各剂量组小鼠扭体次数极显著减少;各剂量组小鼠对二甲苯所致耳肿胀度均有显著或极显著减轻,且各剂量组与雷公藤多苷片组间无显著差异;高剂量组小鼠对角叉菜胶致足肿胀度有极显著减轻,各剂量组与雷公藤多苷片组相比无显著差异。与空白组相比,高、中剂量组小鼠PGE2含量极显著降低;与雷公藤多苷片组相比,高、中剂量组PGE2含量均无显著差异。BLE清除PDDH自由基的清除率随浓度增加呈正相关,IC50为0.029 mg/mL,低于阳性对照维生素C的IC50(0.04 mg/mL),ABTS自由基清除率随浓度增加呈正相关,IC50为0.033 mg/mL,低于阳性对照维生素C的IC50(0.042 mg/mL)。

Abstract: In order to study the analgesia, anti-inflammatory and antioxidant activities of ethyl acetate fraction from the root bark of Acanthopanax trifoliatus(BLE), the analgesia and anti-inflammatory effects of BLE were investigated by hot plate pain method, acetic acid writhing method, xylene-induced mouse ear swelling method, carrageenan-induced mouse paw swelling method and prostaglandin E2(PGE2) content determination. The antioxidant activities of BLE were evaluated by DPPH free radical method and ABTS free radical method. The results showed that compared with the blank group, the pain threshold of each BLE dose group at 60 min was significantly or extremely significantly increased, compared with before medication, the pain threshold of each dose group at each time point was significantly or extremely significantly increased and the difference in the pain threshold of each dose group and tripterygium glycosides tablet group were not significantly indigenous. Compared with the blank group, the writhing times of mice in each dose group were extremely significantly reduced; each dose group could significantly or extremely significantly reduce the ear swelling induced by xylene and there was no significant difference in ear swelling between each dose group and tripterygium glycosides tablets group; the high-dose group could extramely significantly reduce the paw swelling induced by carrageenan, and compared with the tripterygium glycosides tablets group, the paw swelling degrees in each dose group showed no significant difference. Compared with the blank group, the content of PGE2 in high-dose and medium-dose groups was extremely significantly decreased. Compared with the tripterygium glycoside tablet group, there was no significant difference in PGE2 content in high and medium dose groups. The clearance rate of PDDH free radical by BLE was positively correlated with the increase of concentration, with IC50 of 0.029 mg/ml, which was lower than that of the positive control vitamin C (0.04 mg/mL). The clearance rate of ABTS free radical was positively correlated with the increase of concentration, with IC50 of 0.033 mg/mL, which was lower than that of the positive control vitamin C (0.042 mg/mL).

Key words: root bark of Acanthopanax trifoliatus, ethyl acetate fraction, analgesia, anti-inflammatory, antioxidation
