植物来源有豆科植物鹰嘴豆(Cicer arietinum L.)种子的胚芽部分，红车轴草(Trifolium pretense L.)全草等。 鹰嘴豆芽素A(Biochanin A)是一种异黄酮类植物雌激素，发现于红三叶草（红三叶）中，是ER -β选择性雌激素受体激动剂，可能具有预防乳腺癌的化学预防功效。鹰嘴豆芽素A也是芳香烃受体（AhR）的配体。它可以减少阻力，通过对钾和/或钙离子通道的影响微提高循环功能。具有雌激素样作用，能抑制胆固醇的升高，还具有抗真菌和抗肿瘤作用。对人体内的激素水平具有双向调节作用。还有抗癌解痉降血脂作用。 Biochanin A, an isoflavone, is a natural plant phytoestrogen which has been reported to be an antiproliferative and anti-inflammatory agent. Studies show that this compound inhibits iNOS expression and lipopolysacharide (LPS)-induced nitric oxide production in macrophages. Additionally, Biochanin A displays the ability to block phosphorylation of IκBα and p38 MAPK, which prevents NF-κB activation. Furthermore, Biochanin A has been observed to suppress IL-6, IL-1β, and TNF-α production.
