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.
