  • Abstract:

    1. The isolation of an unusual sugar component, viz. a sugar acid derivative, obtained by the hydrolysis of rubellin, is reported. 2. Hydrolysis of pro-rubellidin under various conditions gave products which pointed to the decomposition of pro-rubellidin. 3. Paper chromatography revealed two distinct sugar constituents with low Rf values, in the hydrolysate of rubellin. One constituent which had Rf value 0.14 - 0.16 was the barium salt of the sugar acid obtained by hydrolysis of rubellin, and the other with Rf value 0.28, was obtained on hydrolysis of prorubellidin. 4. The acetylation products of rubellin and pro-rubellidin are described.
