Enrichment of lesquerolic and auricolic acids from hydrolyzed Lesquerella fendleri and L. gordonii oil by crystallization
1997
Frykman, H.B. | Isbell, T.A.
Lesquerolic and auricolic acids were obtained from hydrolyzed lesquerella oil by a low-temperature crystallization procedure. The lesquerolic and auricolic fatty acid fraction was enriched from 55-59% to 85-99% with high yields (94%). Washing the free fatty acids with pH 6.0 buffer provided reproducible crystallizations of those hydroxy fatty acids. In contrast, when hydrolyzed oil from Lesquerella fendleri was not buffer-washed, there was, in most cases, no separation of hydroxy fatty acids by crystallization. This crystallization procedure is suitable for a large-scale separation process of the hydroxy fatty acids from nonhydroxy fatty acids obtained from hydrolyzed lesquerella oil.
