Penentuan Komposisi Fenolik Dan Antiokstoan Pada Kangkung (Ipomea Reptans Poir) Yang Ditanam Secara Organik Dan Konvensional

Abstract

Antioxidant as represent chemical compound that fungtion as resistor of oxidation which cause of free radical. The highest of antioxidant activity influenced by the highest of total size of phenolics or other compound that act as antioxidant in crop. Treatment of crop influence content of total phenol and antioxidant activity. Kangkong {Ipomea reptans Poir) which planted organically with biocontrol which use random group method with three treatment, consist of: 1. FPE grass pahitan {Paspalum conjagatum P.J. Bergius); 2. FPE babadotan {(Ageratum conyzoides Linn); 3. Control. Data analyzed by statistically use ANOVA and continued by DNMRT test level 5%, and compared with plant that planted in conventional. This research purpose to determine profiles of phenolics and antioxidant activity from kangkong {Ipomea reptans Poir) which plant organically (use FPE babadotan and FPE grass pahitan) and conventional. Result of this research indicates that content of total phenolics of kangkong that plant as conventional about 0,982 mg/g fresh weight and antioxidant activity about 41,82%.
