代谢
姜黄素最初会通过O-结合迅速在小肠内代谢,形成姜黄素葡萄糖苷酸和姜黄素硫酸盐。形成的其他代谢物包括四氢姜黄素、六氢姜黄素和六氢姜黄醇,这些是通过还原反应产生的。姜黄素还可能在肝脏中经历密集的二次代谢,其中主要的代谢物是四氢姜黄素和六氢姜黄素的葡萄糖苷酸,以及二氢阿魏酸和阿魏酸的微量作为进一步的代谢物。预计肝代谢物会通过胆汁排出。某些姜黄素代谢物,如四氢姜黄素,保留有抗炎和抗氧化的特性。
Initially, curcumin undergoes rapid intestinal metabolism to form curcumin glucuronide and curcumin sulfate via O-conjugation. Other metabolites formed include tetrahydrocurcumin, hexahydrocurcumin, and hexahydrocurcuminol via reduction. Curcumin may also undergo intensive second metabolism in the liver where the major metabolites were glucuronides of tetrahydrocurcumin and hexahydrocurcumin, with dihydroferulic acid and traces of ferulic acid as further metabolites. Hepatic metabolites are expected to be excreted in the bile. Certain curcumin metabolites, such as tetrahydrocurcumin, retain anti-inflammatory and antioxidant properties.
