Isolation and Study of Dry Extract from Echinacea Purpurea
Medicines based on echinacea can be attributed to the group of herbal remedies that increase the activity of nonspecific factors of the body’s defence and the immune system. The stimulation of bone marrow haematopoiesis with echinacea preparations increases the number of leukocytes and spleen RES cells. Echinacea preparations have a mild, multivalent effect and practically no side effects. A dry extract was obtained from the herb Echinacea purpurea by polyextraction. The con ditions for extraction and the extractants were selected, and the kinetics of extraction, isolation and purification of the extract from the herb Echinacea purpurea were studied.
