Accumulation of flavonoids in the <i>Epilobium angustifoliumL.</i> raw material depending on the places of collection and part of the plant

The aim. Today we are witnessing the actualization of research on plant sources for pharmaceutical and food industries. It is caused by a significant increase in demand these types resources. Therefore, variety case studies aimed at identifying characteristics resources, becoming more actual too. In accordance with this need, present work aims to identify relationship between content flavonoids raw material such important source as Epilobium angustifolium soil climatic conditions group materials. Methods. At first stage were applied cartographic, geographical methods geobotanical description phytocenoses determine most suitable locations purposes study. second method spectrophotometry amount terms rutin correlation analysis. Results. As result application obtained data materials, collected various conditions, well morphological groups These compared analysis after that positive leaves inflorescences was found. Conclusion. determined, fluctuation, depending place growth, 2.05% 2.5% plant. An average 0.65 found leaf angustifolium. However, latitude growth wasn’t identified.
