[摘要]
桦木酸(betulinic acid,BA)属于羽扇豆烷型五环三萜类物质,广泛分布于多种植物中,具有抗肿瘤、抗艾滋病、免疫调节、抗氧化应激、抗菌、抗炎以及抗寄生虫等广泛的药理作用。由于BA具有优越的抗肿瘤和抗艾滋病活性,在恶性肿瘤和艾滋病等威胁人类健康的疾病防治方面具有广阔的应用前景。BA还能提高机体的抗氧化能力、增强免疫力,在机体的抗氧化损伤和免疫调节过程中发挥着重要作用。就BA的药理作用进行详细综述,为BA的研究和开发利用提供参考。

[Abstract]
Betulinic acid (BA) is a naturally occurring pentacyclic triterpene that is widely distributed throughout the plant kingdom. A variety of pharmacological activities have been ascribed to BA, including antitumor, anti-HIV, immunomodulatory, anti-oxidative, antimicrobial, anti-inflammatory, and antihelmintic activities. BA is a very promising new chemotherapeutic agent for the treatment of HIV infection and cancer due to the greater potencies and better therapeutic indices than some clinically used drugs. Notably, BA may play an increasingly important role in immune regulation and against oxidative damage as an immunomodulator and anti-oxidant. The pharmacological activities of BA are reviewed which provide a reference for the future research and utilization of BA.
