文摘

Comprehensive study on elemental contents in medicinal plants from Kenya exceeding the number of samples and elements compared to previous studies. Comparison of samples of the same plant species collected from different locations using multivariate data analysis. Determination of the elemental extraction efficiencies for hot water treatment of the plants to estimate metal dose in traditionally prepared medicine. Sequential (ultra)filtration of aqueous plant extracts for fractionation of the elemental species according to their molecular size.
