腸內酯

化合物

腸內酯(英語:Enterolactone)是一種有機化合物,屬於一種腸木脂素,化學式為C18H18O4。它是由腸道細菌分解食物中存在的植物木脂素產生。

來源

許多膳食植物木脂素前體,如開環異落葉松脂素英語Secoisolariciresinol羅漢松脂酚落葉松脂素英語Lariciresinol芝麻素等可以被腸道菌群代謝產生腸內酯[2][3][4]。在食用植物中,木脂素常與纖維結合,因此富含纖維的食品,如穀物、蔬菜、水果和漿果,通常是木脂素和腸內酯的良好來源。已知最豐富的腸內酯前體膳食來源是亞麻籽和芝麻籽[5][6][7]。腸內酯由特定腸道菌群產生,因此不同的人之間產生腸內酯能力不同[8]。使用抗生素對使腸內酯生產能力下降,而且需要一年才能恢復[9][10]

健康效益

腸內酯被認為對人類具有有益的健康作用。流行病學研究表明,乳腺癌患者的腸內酯濃度低於健康人群,這可能表明腸內酯具有抗癌作用。腸內酯和一些木脂素也可能對心血管疾病有預防作用[11][12]
