title: Cytotoxic activity of plants of family zygophyllaceae and euphorbiaceae.
abstract: The methanolic and n-hexane extracts of studied plants showed significant toxicity to brine shrimps. The methanolic extract of Fagonia cretica had highest LD50 (117.72) value, while Peganum harmala showed low LD50 value (41.70) compared to n-hexane extract. The methanolic and n-hexane extracts of Tribulus terrestris showed similar LD50 values. The methanolic extract of Chrozophora tinctoria showed low LD50 value than the n-hexane extract. The methanolic extract of Ricinus communis showed highest LD50 value while the n-hexane extract showed lowest LD50 value. The LD50 value less than 100 was obtained for n-hexane extracts of Fagonia cretica, Peganum harmala and Ricinus communis. The n-hexane extracts of these plants also showed the highest toxicity as compare to methanolic extracts. The chemical constituents detected in the present investigation might be responsible for cytotoxic activity.
