| Summary: | Abstract
In a continuation of the study on sterol components of Asterina pectinifera, the present study is concerned with mono-unsaturated sterol components. The steryl acetate fraction recovered from the mother liquors of the recrystallizations, which were carried out for the separation of hitodesteryl (α-spinasteryl) acetate in a previous study, was subjected to fractional crystallizations by which two fractions, Δ7-spinastenyl acetate fraction and Δ7-cholestenyl acetate fraction, were eventually separated. Accordingly it has been found that the sterol mixture of Asterina pectinifera contains Δ7-spinastenol and Δ7-cholestenol besides hitodesterol. |
