Comparative analysis of the composition and content of phenolic compounds (PC) in the fruits of three wild species of Malus: Malus mandshurica, Malus chamardabanica, Malus sachalinensis, native to Eastern Siberia and the Far East, was carried out. It was established that the tissues of the fruits of the three species, on the whole, had a qualitative composition of PC characteristic of the genus Malus. Quantitative differences in the content of individual PC were found between the species. The fruits of M. chamardabanica showed a high content of anthocyanins and low flavans. A characteristic feature of the fruit of M. sachalinensis was a high content of dihydrochalcones — more than 50% of the total PC content of. A high (about 80%) content of flavans was found in the fruits of M. mandshurica. At the same time, about 20% of their total amount was was accounted for procyanidin B2, which was not found in the other two species studied. Principal component analysis (PCA) revealed that two principal components (PC1, PC2,) together accounted for more than 99% variation of the total observed variations. PC1 strongly integrated with phloridzin. The data obtained may be of interest for pharmacology, selection of agriculturally valuable traits for breeding new apple varieties, as well as for the study of chemosystematics of the genus Malus.

对原产于东西伯利亚和远东的三种野生苹果属植物（Malus mandshurica、Malus chamardabanica、Malus sachalinensis）果实中酚类化合物（PC）的组成和含量进行了比较分析。确定这三个物种的果实组织总体上具有马鲁属的 PC 特征的定性组成。在物种之间发现个体 PC 含量的数量差异。M. chamardabanica的果实表现出高含量的花青素和低黄烷。M. sachalinensis果实的一个特征是高含量的二氢查耳酮——占 PC 总含量的 50% 以上。在M. mandshurica的果实中发现了高含量（约 80%）的黄烷。同时，它们总量的约20%是原花青素B2，在其他两个研究物种中没有发现。主成分分析 (PCA) 显示，两个主成分（PC1、PC2）一起占观察到的总变异的 99% 以上。PC1 与根皮苷紧密结合。获得的数据可能是对药理学的兴趣，为培育新苹果品种，以及为属chemosystematics的研究农业有价值的性状选择苹果。
