In recent years, researchers are interested and focused on the identification of bioactive
components in plants and food that affects the health, and may also reduce the risk of some
diseases. The research of bioactive components, includes very extensive studies both in
conventional breeding and biotechnological researches, with special reference to the
possibility to increase their content. Alchemilla vulgaris L. is a plant from the Rosaceae
family. Recent scientific research has shown that the source prevents the growth of many
types of bacteria including staphylococci - a bacterium that has become resistant to many
antibiotics. Within the experimental part of this final work, the following analyzes were
performed: preparation of macerates, extraction of samples in the Soxlet apparatus, ultrasonic
extraction and determining the content of vitamin C in the extracts obtained. In determining
the content of vitamin C, we noticed that the highest content of this vitamin, determined in the
extract obtained by maceration (9.75 mg / 100 g), was slightly lower in ultrasonic extraction
(7.50 mg / 100 g), and the smallest content in Soxhlet- of this extract (3.45 mg / 100 g)
