摘 要: 为观察大血藤醇提物抗炎、镇痛、止血活性,该文采用75%乙醇提取制备大血藤醇提物(AESC),利用HPLC法测定其绿原酸含量;KM鼠(或新西兰兔)在测定抗炎、镇痛、止血活性时随机分为空白对照组、阳性对照组(云南白药酊组)、AESC组,依次测定其抑制二甲苯致小鼠耳肿胀度作用、痛阈值和兔肝脏局部创面损伤出血的记分分值,分别考察其抗炎、镇痛、止血作用。结果表明:AESC中绿原酸含量为(0.294 ± 0.013 5)%;与空白组比较,剂量为0.700 g·kg-1 的AESC组能显著减轻二甲苯所致的小鼠耳肿胀度(P<0.01),抑制率达26.3%;与空白组及给药前比较,剂量为1.40 g·kg-1 的AESC组均能显著提高小鼠痛阈值(P<0.01);与空白组相比,剂量为1.40 g·kg-1的 AESC组能显著提高兔肝脏局部创面损伤出血的记分分值(P<0.001)。大血藤醇提取物具有显著的抗炎、镇痛、止血作用,有望将其开发为抗炎、镇痛、止血制剂。该结果也为大血藤的临床应用提供理论依据。

Abstract: To investigate the anti-inflammatory, analgesia and hemostasis effects of the 75% alcohol extract from Sargentodoxa cuneata (AESC). The AESC was prepared by ethanol extraction, and its chlorogenic acid content was determined by HPLC. KM mice (or New Zealand rabbits) were randomly divided into the blank group, positive control group (Yunnan Baiyao Tincture group) and the AESC group in determination of anti-inflammatory, analgesia and hemostasis activities. The anti-inflammatory, analgesic and hemostasis effects were investigated through determining xylene-induced ear swelling of mice, pain threshold and rabbit liver bleeding model. The results were as follows: The content of chlorogenic acid was (0.294 ± 0.013 5)%; Compared with the blank group, AESC group (Dose 0.700 g·kg-1) could significantly reduce the ear swelling induced by xylene (P < 0.01), and the inhibition rate was 26.3%; Compared with the blank group and before administration, AESC group (Dose 1.40 g·kg-1) could significantly increase the pain threshold of mice (P<0.01); Compared with the blank group, AESC group (Dose 1.40 g·kg-1) could significantly improve the score of local wound bleeding (P<0.001). The alcohol extracts of S. cuneata showed significant effects in anti-inflammatory, analgesic and hemostasis, could be developed as the anti-inflammatory, analgesic, hemostatic agents. And this study will provides theoretical basis for clinical application of the S. cuneata.

大血藤(Sargentodoxa cuneata)為木通科(Lardizabalaceae)大血藤属(Sargentodoxa)植物。据2015年版《中国药典》记载,大血藤具有清热解毒、活血、祛风止痛等功效。近年来,大血藤水提物(李华等,2013)、乙酸乙酯部位(陈香君等,2017)、多糖(Guo et al., 2018)等组分均具有抗炎作用。大血藤化学成分3,4-二羟基苯乙醇苷对DSS诱导的结肠炎具有保护作用(Li et al., 2019)。大血藤水提物能抑制二甲苯引起小鼠耳廓肿胀,减轻肿胀度和肿胀率而具有抗炎作用;延长醋酸致疼痛模型小鼠痛阈潜伏期和减少扭体次数,抑制小鼠肉芽组织增生而具有镇痛作用(李华等,2013)。
现代医学主要集中在大血藤水提物、乙酸乙酯部位等的抗炎作用研究。大血藤不仅是风湿痹痛特效药,还具有治疗肠痈腹痛、热毒疮疡、经闭、痛经、崩漏、跌扑肿痛等作用。据文献记载,大血藤服用方法有煎汤、研末、浸酒。本课题组认为,不仅大血藤的水提物具有抗炎活性,其醇提物在抗炎、镇痛和止血方面也具有一定的开发前景。……
