title: Decomposition of 11-deoxycorticosterone and corticosterone in soda-lime glass.
abstract: When methanolic solutions of tritiated 11-deoxycorticosterone or corticosterone (0.1 to 300 ng) were evaporated to dryness with a stream of nitrogen in soda-lime test tubes only 8-24% of the radioactivity was recovered as the parent steroid. Evaporation in borosilicate test tubes led to a recovery of 90% or more. With ethyl acetate as solvent no decomposition occured in soda-lime test tubes.
