Plant species screened in cell viability and alkaline phosphatase assay. Species were separated into plant parts and extracted in methanol. Following the removal of the methanol, extracts were suspended in water and partitioned with hexane, ethyl acetate, and butanol to make 4 distinct fractions (including aqueous) for each plant part. Approximately 100 fractions were initially obtained and assayed for alkaline phosphatase activity and cytotoxicity.
