Abstract A rapid method for the determination of sorbitol in raisins and dietetic foods is described. Sorbitol is converted to a trimethylsilyl derivative after precipitation of interfering organic acids as lead salts and determined by GLC, using α-d-glucoheptose as an internal standard. Nine samples of dietetic foods were analyzed. The results compared satisfactorily with the declared sorbitol content for each product. The recovery of 0.5% sorbitol added to raisins was 93%.

Abstract Column partition chromatography on Celite is used to separate the colors present in lipsticks. In the proposed procedure the immobile phase is aqueous alcohol plus ammonium hydroxide. A small portion of lipstick is ground with a portion of Celite containing the aqueous immobile phase and packed on top of a prepared colrate umn. Solvents of increasing polarity are used to elute individual colors except for one binary mixture. D&C Red No. 19 and D&C Red No. 36 and/or D&C Orange No. 17 elute together.
