The metabolism of caffeic acid, previously shown to be carried out by the intestinal microbiota of man and experimental animals, has now been examined in a number of bacteria isolated from human feces. It has been found that of the 12 organisms isolated none has the ability to catalyze more than one reaction of the series leading from caffeic acid to either m-hydroxyphenylpropionic acid or 4-ethylcatechol.
咖啡酸的代谢此前已表明可由人和实验动物的肠道微生物群进行,现在已对从人粪便中分离出的多种细菌进行了研究。已发现,在分离出的12种微生物中,没有一种能够催化从咖啡酸到间羟基苯丙酸或4-乙基儿茶酚这一系列反应中的多个反应。
