Dracaena trifasciata (Snake plant) and Zamioculcas zamiifolia (ZZ plant) are widely used ornamental plants. This research aimed to investigate the phytochemistry and in vitro antioxidant activity of D.trifasciata and Z. zamiifolia leaves. Freshly prepared juice of D. trifasciata contains flavonoids, phenol, glycosides, terpenoids, monosaccharides, and amino acids, and Z. zamiifolia contains only carbohydrates. In vitro antioxidant studies have shown potential effects in scavenging DPPH and hydrogen peroxide in a concentration-dependent manner. These activities may be due to phytochemicals present in the selected ornamental plants. Keywords: Dracaena trifasciata, Zamioculcas zamiifolia, ornamental plants, DPPH, Hydrogen Peroxide
