Dear all,

I was wondering if anyone could give me some advice/direct me to
publications concerning the extraction of steroids from corals.  I have
been trying to extract oestradiol from a soft coral (Sinularia sp.)
using methanol or diethyl ether.  I partly followed the method of Ann
Tarrant (Comp. Biochem. Physiol. A, 1999), but did not use the celite
columns - is this a critical step?  Any help would be greatly

Thank you,
