A study of the chemical composition and biological activity of extracts from wild carrot (Daucus carota l.) seeds waste
2015
Waste (wild carrot seeds, Daucus carota L.) formed after the industrial extraction of 96% ethanol were re-extracted with 40% and 70% ethanol in order to recover of valuable substances for potential use as a safe food additives and functional food ingredients or nutraceuticals. In this study we compared chemical composition and activity of two obtained extracts (70% EtOH and 40% EtOH). The results indicated that the 70% EtOH extract has a higher total phenol and flavonoid content than 40% EtOH extract. The antioxidant activity of 70% EtOH extract was 86.88 % ± 3.018, whereas of 40% EtOH extract scavenging activity was 78.72% ± 3.276. The extracts were also active against bacteria with MIC ag…

Studied the antimicrobial activity of secondary extract from oregano herbs waste (Origanum vulgare)against 7 standard test strains of microrganisms. Minimum bactericidal concentration of the extract to Staphylococcus aureus ATCC 6538 P-is 3.125-6.25 mg/ml and 6.25-12.5 mg/ml to gram-negative bacteria and Candida albicans ATCC 10231.Total antioxidant activity determined by DPPH, secondary extract at a concentration of 400 ug/ml was 92 %. The tested extract had photoprotective activity. Obtained results confirm the perspective of using waste of oregano herbs for making extracts and creation on their basis of pharmaceuticals, veterinary drugs and cosmetics.
