Recently, 6-(2-naphthyl)-2, 3-dihydro-as-triazine-3-thione (NDTT) was synthesized in laboratory and used successfully for the spectrophotometric determination of nanogram levels of Cu2+ in aqueous solution. This reagent forms a specific red complex with Cu2+ ions after the extraction by chloroform at alkaline pH. The absorption of the complex in the UV region (313 nm) is about 8 times as strong...

This study is focused on the valorization of sugar beet leaves (Beta vulgaris L.), a prominent by-product wasted during process sugar. For doing so, Ultrasound-Assisted Extraction (UAE), Pressurized Liquid (PLE), and Maceration (ME) methods were compared by evaluating extraction yield, Total Phenolic Compounds (TPC), Flavonoid Content (TFC), individual phenolic profile, antioxidant activity (e....
