In this study, the phyto- constituents in Zebrina pendula plant species for dye compounds was established. The phytochemical screening revealed the presence of flavonoids, anthraquinones (emodols) and tannins (both types) as the potential color compounds. Color fastness of the dye on cotton and silk fabrics were also established viz: wash fastness, rub fastness and light fastness. Silk fabrics registered fastness grade of (3) to (4) on a scale of 1 to 5 for both wash and rub fastness with light fastness between (5) and (6) on scale of 1 to 8. Dyed cotton fabrics registered poor wash and rub fastness of (2) with rub and light was of four (4). The toxicological property of plant was studied using  the  Acute  Dermal  Toxicity  test  administered  on  healthy  albino  wistar rat models and female Swiss albino mice in accordance with the OECD test guidelines for analysis  of  chemicals No. 402(1987).  The plant extract registered no dermal  irritation  effects  at  sites  of  application  even  up  to  the  high  dose  levels  of  3200mg/kg  bogy  weight.
