# Extraction of Bioactive Compounds from _Ulva lactuca_
## 5 Highlights  
* _U. lactuca_ is a rich source of bioactive compounds and dietary supplements
* High polysaccharides content (49.9 wt%) was found
* Ethanol/water 70:30 _v/v_ was the most efficient solvent. The optimum extraction parameters were 60 \({}^{\circ}\)C, biomass to solvent ratio 1:10 and 3 h extraction time
* The best extract maintained its high antioxidant capacity for 5 days
