Rezumat

In hyssop feedstock structure the most important component are the flowers which are 36,0% in the production of row material and assures 56,2% of volatile oil production. In pharmaceutical herba production at the beginning of flowering leaves constitute 35,8%, 32,3% at full flowering stage, and drops to 26,9% when hyssop is harvested for obtaining essential oil. Annual semi-lignified hyssop shoots contain very less quantity of volatile oil and therefore their share in the production of essential oil is insignificant. In inflorescences volatile oil content is 0,468% against 0,211% in the leaves, production of volatile oil from leaves and inflorescences being 10,2 and 32,9 kg/ha respectively. Inflorescences have, as in raw material production as in volatile oil production, the highest share.

In structura materiei prime la isop cea mai importantă componentă sunt inflorescențele care constituie 36,0% in producția de materie primă și asigură obținerea a 56,2% in producția de ulei volatil. In producția de herba farmaceutică la inceput de inflorire frunzele alcătuiesc 35,8%, in faza infloririi depline 32,3%, scăzand pană la 26,9% cand isopul se recoltează pentru obținerea uleiului volatil. Lăstarii anuali semi-lignificați la isop conţin numai urme de ulei volatil şi deci ponderea lor in producerea uleiului volatil este nesemnificativă. La inflorescenţe conţinutul de ulei volatil este de 0,468% contra 0,211% in frunze, producţia de ulei volatil din frunze şi inflorescenţe fiind 10,2 şi 32,9 kg/ha respectiv. Ponderea cea mai mare atat in producţia de materie primă, cat şi de ulei volatil o au inflorescenţele.
