The present study included the cytotoxic effects of aqueous crude extracts of Vinca rosea leaves , flowers and seeds on cell line (L20B Cell line)in vitro , by using double dilution series (concentration between 1.95 – 1000 µg/ ml.
The results showed that the cytotoxic effect of extract is dependent on type of extract, amount of dose and exposure time. The concentration 1000 µg/ml gave higher growth inhibition (IR) (74 and 74%) to leaves and flowers respectively compared with control 100% after 24 hours exposure time, but seeds were (49%) after 48 hours. However, low concentrations of aqueous extracts were found to induce the L20B cells growth and proliferation (PR), which recorded (122, 123) % by treatment with flowers extract in 1.95 µg/ ml after 72 hours. Crude aqueous extract of Vinca rosea had hormetic effect (Hormesis), because it also induced the proliferation of cancer cells by using low concentrations of the extract.
