[Spectrophotometric determination of the stichoposide A from the holothurian Stichopus japonicus S].
The absorption spectrum of stichoposid A with sulfuric acid, vanillin and alkaline was studied for the purpose of possibly using the reactions with these substances for quantitative determination of stichoposid A in biological materials. The reaction with 1 N NaOH was shown to be the most useful since it is highly specific with respect to the glycoside aglycone and makes it possible to investigate stichoposid A interaction with the cells of the yeast microflora.
