|Abstract:||Tagara is an important drug used in Ayurvedic medicine for the treatment of several diseases. The accepted botanical source of Tagara is Valeriana jatamasni Jones, although different species of Nymphoides Hill are used by the physicians. The pharmacognostical evaluation of the root and rhizome of Nymphoides hydrophylla, a potential alternative source for Tagara is presented in this paper. Important details like morphology of the plant, macro-, microscopical characters, macerate, histochemical tests, UV studies of the root and rhizome along with physico-chemical constants, phytochemical analysis and HPTLC finger print profile are presented, all of which will be useful in the standardization of this drug. Isolation of β-sitosterol, betulinic, salicylic and tannic acids are reported for the first time from N. hydrophylla. The pharmacognostical and phytochemical studies help in the identification of N. hydrophylla from other species used as Tagara.|
