Rezumat

The content of known tetra- and pentacyclic diterpenoids in extracts of sunflower (Helianthus annuus L.) dry wastes has been studied using different solvents for extraction. It was established that the largest extracted quantity of ent-kaur-16-en-19-oic acid is obtained when ethanol and diethyl ether are used for extraction of the plant material.

Cuvinte-cheie
ent-kaur-16-en-19-oic acid, 15α-angeloyl-ent-kaur-16-en-19-oic acid, ent-trachiloban-19-oic acid, diterpene, extraction.
