Micromorphological and phytochemical analysis on the tubers of Typhonium trilobatum

Abstract

Microscopic, morphological and qualitative phytochemical analysis were conducted in the tubers of Typhonium trilobatum (Linn.) Schott, member of the botanical family Araceae. Tubers are eaten in some tribal societies and the plant also has various medicinal uses. Parameters presented in this paper may establish the authenticity of this plant and can possibly help to differentiate the drug from its closely related plants, like Sauromatum or Lazarum which show similarity morphologically but differ anatomically. Sections were taken and camera lucida diagrams were drawn, powder microscopy showed the presence of cork, abundant starch grains and raphides. Phytochemical tests revealed presence of proteins, fats, flavonoids, phenols and alkaloids, while steroids, tannin and glycosides were negligible in the alcoholic and chloroform extracts. The uses of this plant in traditional medicine is for various ailments but its flavonoid content opens doors for treatment in cancer of all types.
