The temperature-dependent separation of bryostatins by HPLC was examined on
an octadecyl bonded stationary phase, using column temperatures between 0
and 40 degreesC and mobile phase temperatures from 0 to 25 degreesC. The re
tention time and resolution of bryostatins changed drastically and separati
on improved with decreasing temperature. A column temperature of less than
5 degreesC and a mobile phase temperature of less than 15 degreesC is recom
mended for a good resolution of bryostatins for routine work.
