The chemical composition of elder
Black elder flowers contain:
- flavonoids (1.5-3.0%): quercetin, kaempferol and their glycosides - hyperoside, isoquercitrin, rutin, astragalin;
- triterpenoids (alpha and beta amyrin, oleanolic and ursolic acids);
- cyanogenic glycoside sambunigrin, hydrocyanic acid, benzaldehyde and glucose;
- essential oil (0.27-0.32%);
- phenolic (para-coumaric, chlorogenic) and organic acids (malic, acetic, and valeric).
Harvesting and storage of raw materials
Harvesting. During the flowering of plants before the beginning of the shedding of corolla (June - July), whole inflorescences are cut with secateurs. At a later harvest, the flowers darken when dried.
Security measures. When harvesting it is forbidden to break the branches of elder, as this leads to the destruction of thickets.
Drying. It is dried in attics or under sheds with good ventilation, putting inflorescences in one layer is no thicker than 1 cm on plain paper. The end of drying is determined by the fragility of the branches of the inflorescence. It can be dried in dryers with artificial heating at a temperature not higher than 40-50 °C. After drying, the inflorescences are threshed (usually manually, with sticks) and the flowers are separated from the twigs of the inflorescence and other impurities on the sieves or fanashes.
Storage. Elder raw materials easily dampen and moldy. Elder flowers are packed in boxes. It is stored on shelves in dry, dark and well-ventilated areas.
