Angelica archangelica (Apiaceae) grows in damp places in northern and eastern Europe and is commonly used in folk medicine as a remedy for nervousness, insomnia, stomach and intestinal disturbances, and arthritis. The plant is generally cultivated for its roots, which are richer in oils than the other organs and whose oil is esteemed for its use in flavouring and in making perfumes. In Europe, the essential oil from Angelica archangelica is employed in liquors, dental preparations and in high-grade perfumery to impart a musky note, which cannot be distinguished easily from that of true musk. Angelica archangelica is a threatened aromatic herb for which ex situ cultivation is recommended as a conservational tool. The aim of this work was to characterize the ecophysiological and edaphic parameters. We measured the leaf gas exchange, assimilatory pigments content, soil pH, hydrolytic acidity (HA), cation exchange bases sum (BC), total cation exchange capacity (CEC), cation saturation level (BS). Physiological determinations were correlated with light intensity, air temperature and humidity. The results of pH soil are part from slightly soil acid reaction category. Hydrolytic acidity value was 4.6 meq/100 g. Results will be used to achieve a nutrient mixture on the propagation of rare medicinal species. At a light intensity of 3000 lux, 64% humidity and a temperature of 20°C, the photosynthetic rate was 1.479 μmol CO2 m-2 s-1, and the respiration rate was 0.425 μmol CO2 m-2 s-1. The present paper deals with improvement of knowledge for the preparation of nutritive substrates used in the technologies for Angelica archangelica.
