Uticaj brzine hidrodestilacije i hidromodula na hemijski sastav etarskog ulja kleke (Juniperus communis L.)

Izvod U radu su prikazane promene hemijskog sastava etarskog ulja dobijenog hidrodestilacijom ploda kleke u zavisnosti od brzine destilacije i odnosa mase kleka−voda (hidromodula). Odabrane su 23 komponente (od ukupno 58 određenih) sa masenim udelom većim od 0,5%. Najzastupljeniji su bili monoterpeni, zatim seskviterpeni i mnogo manje oksigenovani ugljovodonici. Prema isparljivosti, najviše je bilo lakoisparljivih, zatim teškoisparljivih i najmanje srednjeisparljivih komponenata. Sa povećanjem brzine destilacije, maseni udeo lakoisparljivih i srednjeisparljivih komponenti se smanjuje, dok se maseni udeo teškoisparljivih komponenti povećava. Promene hidromodula su znatno manje uticale na maseni sastav nego promene brzine destilacije. Eksperimente hidrodestilacije treba nastaviti pri različitim brzinama destilacije, uključujući istovremenu rektifikaciju, uticaj pripreme kleke i određivanje optimalne potrošnje energije.
