Effect of aqueous extract of Colpomenia sinuosa on some secondary products in lupine

Colpomenia sinuosa was gathered, and the location was near the Red Sea coast of Egypt at Hurghada.. Seeds of Lupinus termis were primed in distinctive concentrations (0, 50, 100, 150, 200, 250 ml/L) of aqueous extract from C. sinuosa followed by growing in Hogland’s solution. The different bioactive substances, such as total phenols, total flavonoids, total flavonols, and total tannins, were identified using lupine leaf extracts.The findings show that, based on the concentration of the examined C. sinuosa extract, the four bioactive components were elevated at varying rates.The results suggest priming of plant seeds in seaweed extracts during germination to enhance the antioxidant compounds which have various biological activites particulerly the antioxidant activity
