This paper presents the results of experimental development of a technology for obtaining an oil extract from a collection of medicinal plants, including the root of the naked sorrel, the herb of the burdock plant, the rhizome of the calamus, the rhizome of the rosehip plant, and the herb of the zeroba plant. Sunflower oil was used as an extractant.
Before matzing, the plant material was treated with ethyl alcohol, and the extraction process itself was intensified using fermentation (cellulose) and ultrasound. Step-by-step, one-factor optimization of key technological parameters was performed: degree of raw material, hydromodule process, temperature, extraction time, and ultrasound performance. The process's effectiveness was assessed by the total flavonoid content, determined spectrophotometrically in comparison with rutin . The resulting extract is promising for both dermatological and nutritive purposes.
