Effect of Different Light Intensities on Total Phenolics and Flavonoids Synthesis and Anti-oxidant Activities in Young Ginger Varieties (Zingiber officinale Roscoe)

摘要: Nowadays, phytochemicals and antioxidants in plants are raising interest consumers for their roles the maintenance of human health. Phenolics flavonoids known health-promoting properties due to protective effects against cardiovascular disease, cancers other disease. Ginger (Zingiber officinale) is one traditional folk medicinal it widely used cooking Malaysia. In this study, four levels glasshouse light intensities (310, 460, 630 790 μmol m−2s−1) were order consider effect intensity on production, accumulation partitioning total phenolics (TP), (TF) antioxidant activities two varieties Malaysian young ginger officinale). TF biosynthesis was highest Halia Bara variety under 310 m−2s−1 TP high a m−2s−1. The amount these components accumulated leaves after that rhizomes. Also, determined by 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) assay both varieties, increased significantly (p ≤ 0.01) with increasing concentration, activity observed grown ferric reducing (FRAP) rhizomes higher than sun light. This study indicates ability different enhance Zingiber officinale varieties. Additionally, also validated potential based contents.
