肠内酯（英语：Enterolactone）是一种有机化合物，属于一种肠木脂素，化学式为C18H18O4。它是由肠道细菌分解食物中存在的植物木脂素产生。
来源
[编辑]许多膳食植物木脂素前体，如开环异落叶松脂素、罗汉松脂酚、落叶松脂素和芝麻素等可以被肠道菌群代谢产生肠内酯[2][3][4]。在食用植物中，木脂素常与纤维结合，因此富含纤维的食品，如谷物、蔬菜、水果和浆果，通常是木脂素和肠内酯的良好来源。已知最丰富的肠内酯前体膳食来源是亚麻籽和芝麻籽[5][6][7]。肠内酯由特定肠道菌群产生，因此不同的人之间产生肠内酯能力不同[8]。使用抗生素对使肠内酯生产能力下降，而且需要一年才能恢复[9][10]。
健康效益
[编辑]肠内酯被认为对人类具有有益的健康作用。流行病学研究表明，乳腺癌患者的肠内酯浓度低于健康人群，这可能表明肠内酯具有抗癌作用。肠内酯和一些木脂素也可能对心血管疾病有预防作用[11][12]。
