Preliminary Phytochemical Screening of Different Extracts of Whole Plant of Enicostemma littorale Blume

Abstract

Enicostemma littorale Blume (Gentianaceae family), which is commonly known as Mamajaka (Sanskrit), Vellarugu (Tamil) and Indian gentian (English). E. littorale is a perennial herb which grows in coastal areas of Northern and Eastern province of Sri Lanka. The whole plant is dried and powdered and used to treat rheumatism, swelling, back pain, diabetes mellitus, constipation, and skin diseases. The aim of this study is to evaluate the phytochemical constituents in different extracts of E. littorale according to the standard procedures. Quantitative estimation of some of the active constituents like alkaloids, flavonoids and saponins were also carried out. The preliminary phytochemical screening of hot and cold ethanol, methanol and aqueous extracts showed the presence of alkaloids, saponins, flavonoids, steroids, tannins, proteins, reducing sugar coumarins and quinones and absence of anthraquinones. Cold and hot water extracts showed the presence of fat and fixed oil. The total alkaloid and flavonoid contents were found to be 2.25
