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 spectrum (maxima in light petroleum 482 and 452 mp) Zone IV. This was a brownish yellow band. The pigment was extracted and identified as neo-,B-carotene B (maxima in petroleum 470 and 443 m,u.). It yielded a single band on mixed chromatography with neo-,B-carotene B prepared by HCI treatment of ,-carotene (Sadana, 1949). Results of analyses of six varieties of loquats varying in colour from pale yellow to deep orange are shown in Table 1.
