Variability total phenolic content and antioxidant activity of Curcuma zanthorrhiza and C. aeruginosa cultivated in three different locations in West Java, Indonesia

Abstract. Suryani, Al Anshory AC, Marlin, Artika IM, Ambarsari L, Nurcholis W. 2022. Variability total phenolic content and antioxidant activity of Curcuma zanthorrhiza C. aeruginosa cultivated in three different locations West Java, Indonesia. Biodiversitas 23: 1998-2003. Roxb. are medicinal plants belonging to the Zingiberaceae family, which contained compounds. Phenolic is one This study aimed investigate variation on varieties twenty genotypes Total was determined using Folin-Ciocalteu reagent, whereas used spectrophotometry DPPH method. The ranged from 2.403 7.539 mg GAE/ g DW) differed significantly among varieties/genotypes, with highest concentration found Cursina 3 variety Cianjur. 2.443 14.960 µmol TE/g DW, maximum identified 2 Bogor location. G1, G6, G13, G16 were as stable for production. Three cultivars demonstrated higher than all planting areas. most promising source thus recommended mass plantation at suitable Indonesia maximize potential.
