Phytochemistry Thin layer Chromatography and Antioxidant activity of Typhonium trilobatum (L.) Schott, Amorphophallus paeoniifolius (Dennst.) Nicolson, Colocasia esculenta (L.) Schott

Abstract

           Typhonium trilobatum (L.) Schott , Amorphophallus paeoniifolius (Dennst.) Nicolson ,Colocasia esculenta (L.) Schott. Found throughout all regions of Thailand.  Has  medicinal properties in treating diseases such  as skin symptoms, suppurative abscess, cure constipation,resolve inflam mation  and  pain , so  this  research is to study the phytochemicals of all three plants by soxhlet extraction method , it was found that it T. trilobat um and A. paeoniifolius found flavonoid substances.                                                   And steroids are found in all 3 plants. Studies of antioxidant activity found  that  T. trilobatum  and   A. paeoniifolius have antioxidant activity with IC₅₀ value at 140.58,193.89 microgram/milliliter respectively,but also less free radicals than the standard ascorbic acid with IC₅₀ value at  2.300 micrograms/milliliter.                                                                                                          IC₅₀  values of  C. esculenta may be found at the concentration of the extracts tested greater than 500 micrograms/milliliter.                                Thin layer Chroma tography showed that all 3 plant extracts did not find the band when reading with UV 254 nm but have band at UV 366 nm.
