Kadar Flavonoid dan Fenolik Ekstrak Daun Waru (Hibiscus tiliaceus) Serta Aktivitasnya Sebagai Antioksidan

Waru leaf (Hibiscus tiliaceus) is plant that contains natural flavonoids and phenolic compounds useful as an antioxidant. Flavonoids phenolics can be extracted optimally if using a suitable extraction solvents. This study aims to determine the total flavonoid, phenolic, antioxidant levels of waru extract several The flavonoid content was tested AlCl3 colorimetric method, Folin-Ciocalteu DPPH method. with methanol, ethanol, water solvents respectively 121,630 ± 2,014 gQE/g; 133,190 1,434 78.320 1.799 gQE/g. were 9,151,480 58,969 gGAE/g; 7,978,610 84,845 4,789,690 14,576 gGAE/g.
