acid methyl esters. In contrast, the reaction of CLA methyl ester with SeO2 gave di-hydroxylated derivatives as novel products including, erythro-12,13-dihydroxy-10E-octadecenoic acid, erythro-11,12-dihydroxy-9E-octadecenoic acid, erythro-10,11-dihydroxy-12E-octadecenoic acid and erythro-9,10-dihydroxy-11E-octadecenoic acid methyl esters. These products were purified by normal-phase short column vacuum
由亚油酸(LA)和共轭亚油酸(CLA)制备C18不饱和脂肪酸的烯丙基羟基化衍生物。LA甲酯与二氧化硒(SeO 2)的反应生成了单羟基化衍生物13-羟基-9 Z,11 E-十八碳二烯酸,13-羟基-9 E,11 E-十八碳二烯酸,9-羟基10 E,12 Z-十八碳二烯酸和9-羟基-10 E,12 E-十八碳二烯酸甲酯。相比之下,CLA甲酯与SeO 2的反应产生了二羟基化的衍生物,其为新产物,包括赤藓红-12,13二羟基10 é十八碳酸,电子rythro -11,12二羟基-9- ë十八碳酸,赤-10,11-二羟基- 12 é十八碳酸和赤-9,10-二羟基11 E-十八碳烯酸甲酯。这些产物通过正相短柱真空色谱法,然后用高效液相色谱法(HPLC)纯化。它们的化学结构通过液相色谱-质谱(LC-MS)和核磁共振波谱(NMR)进行表征。LA和CLA的烯丙基羟基化衍生物在体外显示中等对一组人类癌细胞系的
