Abstract

By degrading betanidin with alkali under exclusion of oxygen it was possible to demonstrate the formation of 4‐methylpyridine‐2, 6‐dicarboxylic acid (II), 2, 3‐dihydro‐5, 6‐dihydroxyindole‐2‐carboxylic acid (IV) and formic acid. Compounds II and IV were also found after a treatment with acid. In this way all the 18 carbon atoms of betanidin are accounted for by degradation.

## Abstract Two aglucones of betanin, called betanidin and __iso__betanidin, are described. Empirical formulas (C~19~H~18–20~O~8~N~2~) and certain structural features are deduced for them. Degradations of the aglucones are shown to yield indole and pyridine compounds.

## Abstract A choice between structures I and III for betanidin is now possible in favour of I on the basis of the formation of a well‐characterized di‐O‐acetylderivative (II). The instability of betanidin and its ready transformation into other products at elevated pH's are shown to be due to its
