This present work described the chick embryo cell line fibroblast toxicity on control and induced cells. Observation
was made on selected plant extract on fibroblast during 2013-14 under laboratory condition. Twenty plant species
were selected for their establishment and three species were found high percent viability such as Tinospora
cardifolia (82.33%), Plumbago zeylanica (76.66%) and Withania somnifers (69.81%). Species Crosandrin
fundibulformis (23.07%) and Cathranthus rosae (18%) were reported lowest viability. The viability varies species
to species and discussed.
