Determination of the content of bioactive components in different extracts of celery leaves (Apium graveolens L.)

Plants with active compounds, i.e. those that have medicinal properties have been used since ancient times both for medicinal purposes and for preserving food. The aim of the work is to determine the most optimal extraction method for obtaining the highest yield of vitamin C and organic acids from celery leaves, which could have potential application in the food industry. Three extraction methods were combined, the density of the obtained extracts, the content of vitamin C and the content of organic acids were measured. The correlation of the content of bioactive components and the density of the obtained extracts was monitored.
