| Outline of Final Research Achievements |
Apple leaves are discarded in large quantities to facilitate the growth of apple fruits. In the study, to beneficially utilize the apple leaves, we tried to isolate some components from the leaves. Form the methanol (MeOH) extract of apple leaves, 10 kinds of components were successfully isolated and identified. Some of the components strongly inhibited catecholamine and/or cortisol secretion called stress hormones from bovine adrenal cells. Further, some disorders induced by stress were avoided in the mouse when the MeOH extract was pre-administered to mouse. Therefore, it is possible that apple leaves discarded in large amounts during the cultivation process of apple fruits are utilized as the resources of medicines.
