"1. Introduction

Studies on the chemical biodiversity of plants are recognized as being
relevant and are carried out with the aim of enriching the assortment of
raw medicinal plant materials and to evaluate their potential application
to the demands of practical medicine. A search for plants accumulating
phenolic compounds, which have recently been considered as an object of
many scientific studies, is especially promising. It is of importance to
assess the composition and content of phenolic compounds in plant
vegetative organs, to determine the patterns of their accumulation and
identify new, promising sources of plant phenolic compounds.

The domestic apple (Malus domestica Borkh.) is one of the most widely
cultivated fruit trees. Although the chemical composition of apples has
been extensively investigated [1, 2], we have failed to find any data on
the composition and content of phenolic compounds in the leaves of
different apple cultivars grown in Lithuania. Comprehensive data of
scientific research on the variation in the composition and content of
phenolic compounds would allow conducting purposeful studies leading to
the usage of the raw material obtained from apple leaves as a potential
source of phenolic compounds in practical medicine. Biologically active
compounds could lead to production of dietary supplements and cosmetic
preparations enriched in phenolic compounds found in apple leaves. Small-
scale studies on the chemical composition of leaves have been published,
where phloretin glycosides, phenolic acids, catechins, and some quercetin
glycosides were identified as the main phenolic compounds [3–5]. Other
studies on the composition and content of phenolic compounds in apple
leaves were conducted in relation to Venturia inaequalis-caused
infections in the vegetative organs of apple trees. Phenolic compounds
accumulated in fruit plants play an important role in the plant defense
mechanism against different fungal diseases and different stresses [6–9]."
