Bioactive compounds in nettle leaves influenced by pressurized liquid extraction
Nettle leaves possess valuable bioactive compounds with potential application in food and pharmaceutical industries. Various extraction techniques are used for the bioactive compounds isolation, among which pressurized liquid extraction (PLE) represent very effective and eco-friendly technique. Hence, this study aimed to determine the conditions for the highest yield of total phenols and total pigments from nettle leaves (Urtica dioica L.) during PLE with 96% ethanol as solvent. Parameters varied during the experiment were: extraction temperature (20, 50, 80 and 110 ℃), static extraction time (5, 10 min) and number of extraction cycles (1, 2, 3 and 4). Obtained extracts were spectrophotometrically analyzed for content of total phenols, total chlorophylls and total carotenoids. Furthermore, all obtained data were statistically analyzed (MANOVA). Results showed that total phenols content in nettle leaves ranged from 106, 44 - 1199, 7 mg GAE/100 g of dry material, total chlorophylls were determined in the range of 161, 31 - 936, 43 mg/100 g of dry material, while total carotenoids content ranged from 38, 62 - 154, 89 mg/100 g of dry material. Statistical analysis showed that the highest content of total phenols and total pigments from nettle leaves extracted by PLE were achieved at 110 ℃/10 min/4 cycles.
