Procurement and storage . Leaves (Folia Juglandis regiae), green fertile (Cortex Juglandis regiae fructibus) and green, unripe fruits are used to make medicines. The leaves are collected, pinching them from the central petiole, in dry weather and after the dew disappears, and immediately dried, spreading in a thin layer and turning over from time to time. Blackened leaves are discarded. 23-25% of dry raw material is obtained. Fertilizers are collected during fruit harvesting. They are cut in half and dried in warm rooms or in dryers at a temperature of 30-40°. 20% of dry raw materials are obtained. Dry leaves and fruits are exported. Pharmacies do not release such raw materials. Green, unripe fruits are collected in the period of milk-wax ripeness, when the inner shell is still easily cut with a knife.

Chemical composition. Leaves and fruits contain flavonoids, tannins, alkaloids, vitamins B1 , E, ascorbic acid (up to 3000 mg%), carotene (over 30 mg%), essential oil (0.06%), caffeic acid, trace elements, as well as coloring substance juglone (5-oxy-1,4-naphthoquinone). The kernel of nuts has 52-78% fatty oil, 9-20% protein, 13-20% carbohydrates, tannins and aromatic substances, vitamins and compounds of iron and cobalt.
