COMPARATIVE CHARACTERISTICS OF SOME PLANTS FAMILY HEATHER EXTRACTS AND THE EFFECTIVENESS OF METHODS FOR THEIR PRODUCTION

The paper presents new data related to the comparative study of water-alcohol leaf extracts heather plants family (highbush blueberry, lingonberry, heather). Leaf were obtained by three methods, two which using ultrasonic emitters (an ultrasound bath and a submersible probe), third method, thermal (traditional), was chosen as comparison. are characterized parameters total content extractive substances, sum phenolic compounds, flavonoids, dispersed phase size particles distribution determined method dynamic light scattering, quantitative assessment integral antioxidant activity is given. It has been established that probing highest in extracting compounds flavonoids from lingonberry leaves grass, at same time level their inferior traditional plant raw materials boiled with extractant. values extractives for all types average flavonoids. There observed significant increase <1000 nm "ultrasonic" compared however this pattern not fulfilled other materials. All herb have high polydispersity greatest tendency sediment formation during storage.
