Abstract :
Natural extracts from plants are one of the most important primary sources for the preparation of preservatives, flavorings, cosmetics, perfumery, dyes, and medicines. Extracting effective substances and natural extracts from different plants is a very important thing that researchers in different fields pay special attention to. Considering the need of societies to extract effective plant compounds, it has led to wider researches in the field of introducing extraction processes. There are various extraction methods to extract active plant compounds. Traditional methods of obtaining natural compounds of plants, such as water distillation or steam extraction and extraction with organic solvent, have disadvantages such as loss of volatile compounds, low efficiency, long extraction time, destruction of unsaturated compounds and the remaining toxic solvent. In order to improve the efficiency of extracting effective substances from medicinal plants, new methods have been invented. One of these methods is the use of ultrasound waves. The purpose of this study is to know more about the new method of extraction with the help of ultrasound waves, along with its advantages and disadvantages compared to other methods. According to the results of this study, ultrasonic extraction method is a new, fast, efficient and cost-effective method for extracting effective compounds from plant texture.
