Response surface methodology (RSM) was applied to predict optimum conditions for extraction of lavonoid from Coreopsis tinctoria Nutt. A central composite design (CCD) was used to monitor the effect of extraction temperature, extraction time, and water-to-material ratio on yield of total lavonoids. The optimal extraction conditions were obtained as water-to-material ratio of 55 ml g-1, extraction temperature of 80 °C and extraction time of 70 minutes. Under these conditions, the average total lavonoids yield, according to the mass of raw material, was 9.0 ± 0.6 %, which corresponds to the predicted value of 8.9 %. Thus, the extraction method was applied successfully to extract total lavonoids from C. tinctoria. [ABSTRACT FROM AUTHOR] |
| Abstract (Croatian): |
Metodom odzivne površine (RSM) utvrđeni su optimalni uvjeti za ekstrakciju flavonoida iz Coreopsis tinctoria. Središnje kompozitni plan (CCD) primijenjen je za praćenje utjecaja temperature, vremena te omjera vode i sirovog materijala na prinos ukupnih flavonoida. Optimalni ekstrakcijski uvjeti su omjer vode i materijala 55 ml g-1, temperatura 80 °C i ekstrakcijsko vrijeme 70 min. Pri tim uvjetima prosječno iskorištenje ekstrakcije ukupnih flavonoida u odnosu na sirovi materijal bilo je 9,0 ± 0.6 %, što se slaže s predviđenom vrijednosti 8,9 %. Ekstrakcija je uspješno primijenjena za ekstrakciju ukupnih flavonoida iz C. tinctoria. [ABSTRACT FROM AUTHOR] |
