黃芪甲苷是黃芪的主要有效成分，隨著對黃芪甲苷藥理作用的深入研究發(fā)現(xiàn)，其具有調(diào)節(jié)免疫、缺血保護、心臟保護、抗炎、抗病毒和抗腫瘤等作用，綜述黃芪甲苷藥理作用的研究進展，并對其作用機制進行探討，為進一步研究開發(fā)黃芪甲苷提供理論依據(jù)。

Astragaloside IV is the major effective component isolated from Astragali Radix. The further studies on the pharmacological activities in recent years have demonstrated that astragaloside IV plays a role in regulation of the immune, ischemia protection, heart protection, anti-inflammation, antiviral action, and anti-tumor, etc. The pharmacological activities of astragaloside IV are reviewed in this paper, and its mechanism of action is also discussed, in order to provide theoretical foundation for further development.
