Saccharides II and III were obtained on catalytic hydrogenolysis of carminomycins II and III. The saccharides contained daunosamine and a nitrogen-free fragment of unknown structure. Crotonic aldehyde in the form of 2,4-dinitrophenylhydrazone and 1,2-propylenglycol in the form of 3,5-dinitrobenzoate were isolated on acid hydrolysis of the saccharides. The study on the chemical and spectral properties (PMR-spectra) of the saccharides, their N,O-acetates and hydrolysis products suggested the structure of th carbohydrate moiety of carminomycins II and III as a disaccharide of daunosamine and acyclic semiacetal of 2,4-desoxytetrose.
糖 II 和糖 III 是通过对洋红霉素 II 和洋红霉素 III 进行催化氢解得到的。这些糖含有柔红糖胺和结构未知的无氮片段。在对这些糖进行酸水解时，分离得到了呈 2,4-二硝基苯腙形式的巴豆醛和呈 3,5-二硝基苯甲酸酯形式的 1,2-丙二醇。对这些糖、它们的 N,O-乙酸酯以及水解产物的化学和光谱性质（核磁共振谱）的研究表明，洋红霉素 II 和洋红霉素 III 的碳水化合物部分的结构是柔红糖胺二糖和 2,4-脱氧四糖的无环半缩醛。
