研究了电流作用下从固体植物原料（树皮和根）中提取酚类抗氧化剂。发现了提取的酚类化合物的量和抗氧化活性与植物原料的粒径和研磨程序之间的关系。在研磨样品的实验中实现了最完全的酚类提取。所得的箭木 (Viburnum opulus L.) 树皮和地榆 (Sanguisorba officinalis L.) 根提取物的抗氧化活性优于索氏提取器循环提取的提取物，并且将葵花籽油的氧化稳定性提高了 2-3 倍。
The extraction of phenolic antioxidants from solid plant raw materials (bark and roots) under the action of an electric current was studied. A relationship between the amount and antioxidant activity of extracted phenolic compounds with the particle size and the procedure of grinding plant raw material was found. The most complete extraction of phenols was reached in experiments with ground samples. The resulting extracts from the bark of arrowwood (Viburnum opulus L.) and the root of burnet (Sanguisorba officinalis L.) were superior to the extracts obtained by circulation extraction in a Soxhlet extractor in terms of the antioxidant activity, and they increased the stability of sunflower oil to oxidation by a factor of 2-3.
