Filter-paper partition chromatography of sugars

Improved separation of sugars on the paper partition chromatogram.

450-5 m,u.)since it yielded a singleband on mixed chromatography with cryptoxanthin obtained from yellow maize (Sadana, 1946). Zone II. This was an orange-coloured band. The pigment was identified as neo-,-carotene U (maxima in light petroleum 480 and 450 mp.; Sadana, 1949). Zone III. This was reddish orange in colour. The pigment was extracted and identified as $-carotene by its absorption spe...

The quantitative separation of estrogens by paper partition chromatography.

The varying success of known chromat’ographic procedures for the separation and identification of microquantities of estrogens (1, 2) has led to the development of paper partit!ion chromatographic techniques which are reported here. These t’echniques permit rapid separation, identification, and quantitative estimation of free est.rogens in biological materials. The solvent systems of o-dichloro...

The separation of esters of choline by filter-paper chromatography.

7. It is concluded that tran8-tran8-muconic acid is probably a true metabolite of benzene and is not produced in vivo from the ci8-ci8-acid. It is suggested that the 68-c68-acid need not be an intermediate in the formation of the tran8-tranm-acid in the animal body. The expense of this work was in part defrayed by a grant from the Medical Research Council. We are grateful to Prof. R. Cruickshan...
