Abstract

Kamilica (Matricaria chamomilla L.) je poznata ljekovita, jednogodišnja biljka iz porodice Asteraceae koja se često naziva „zvijezda među ljekovitim vrstama“. Eterično ulje prisutno u cvatu sadrži azulen i koristi se u parfumeriji te farmaceutskoj industriji. Suhi cvat kamilice u velikoj je potražnji za upotrebu u biljnim čajevima. Kamilica sadrži veliku skupinu terapijski zanimljivih i biološki aktivnih spojeva od seskviterpena, flavonoida, kumarina do vitamina, fenolnih kiselina i glukozida. Cilj ovog istraživanja bio je istražiti sadržaj bioaktivnih spojeva u etanolnom i vodenom ekstraktu cvijeta kamilice i ispitati utjecaj ultrazvučne ekstrakcije na prinos istih. Analizirani su vodeni i etanolni ekstrakti, i to: gustoća, topljiva suha tvar, ukupne kiseline, pH-vrijednost, volumni alkoholni sadržaj, vitamin C, ukupni fenoli (flavonoidi i neflavonoidi) i antioksidacijski kapacitet. Primjena ultrazvuka visokog intenziteta značajno je smanjila vrijeme potrebno za ekstrakciju biljnog materijala. Ultrazvuk visokog intenziteta u usporedbi s klasičnim načinom ekstrakcije bioaktivnih spojeva iz cvijeta kamilice utječe na povećanje sadržaja ukupnih fenola i flavonoida.

Abstract (english)

Camomile (Matricaria chamomilla L.) is well known as therapeutic, annual plant from Asteraceae kind which is often called “star among therapeutic sorts”. Essential oil present in floral fronts contains azulene and is used in drugstores and pharmaceutical industry. Dry inflorescence of camomile is in demand for use in herbal tea. Camomile contains great group of therapeutically interesting and biological active compounds of sesquiterpenes, flavonoids, coumarins, vitamins, phenol acids and glucosides. The aim of this research was to examine content of bioactive compounds in ethanol and water extract of camomile flower. Moreover, examine the influence of ultrasound extraction on productivity of the same. In water and ethanol extracts have been analysed: density, dry matter content, total acids, pH- value, volume alcohol content, vitamin C content, total phenols (flavonoids and nonflavonoids) and antioxidant capacity. The use of high intensity ultrasound has significantly decreased time necessary for extraction of herbal material. High intensity ultrasound compared to the classic method of extracting bioactive compounds from the chamomile flower affects on the increase in the content of total phenols and flavonoids.
