Analysis of Alocasia Macrorrhiza Solutions and Extracts
The aim of this research is to analyze solutions and extracts of Alocasia Macrorrhiza, a houseplant of Araceae family which is used in traditional medicine to treat respiratory diseases, tuberculosis, osteoarthritis, as a wound healing and anti-inflammatory agent. Leaves and petioles (aerial part) of Alocasia cultivated in the cities of Barnaul, Pavlovsk and Belokurikha have been used in research. Fresh and dry raw materials as well as solutions and extracts have been analyzed. For qualitative analysis the extract of aerial parts of Alocasia makrorrhiza has been obtained by one-month macerating of a medium size leaf in 0.5 l of 40% (or 70%) alcohol solution (prepared by analogy with tinctures of traditional medicine). Chromatographic methods of extraction and systematic qualitative analysis have revealed ions of mercury (II), iron, potassium, ammonium, nitrate, sulfate, bromide. The quantitative content of iron has been estimated by means of photometric method with the formation of a complex with sulfosalicylic acid, and potentiometric titration with sodium ethylenediaminetetraacetate.
