Preliminary pharmacognostic and phytochemical standardization of Dhataki [Woodfordia fruticosa (L.) Kurz.] leaves.

Abstract

Background:Woodfordia fruticosa (L.) Kurz., known as Dhataki, is an important medicinal plant used in Ayurveda. Recent studies on leaf showed that it contains important chemical constituents responsible for biological activities. The ethnic folk from India and Nepal are using the leaf to treat ulcers, rheumatism, fever, hemoptysis and as a disinfectant. It is also reported to be used in perfume, leather and textile industries.Aim:To investigate preliminary pharmacognostical and phytochemical parameters of leaf to standardize the drug.Materials and Methods:Identification of plant was done as per the standard guidelines given in the floras. Macro and microscopic evaluation performed as per the routine laboratory procedures. Phytochemical, physico-chemical, florescence analysis, behavior of powdered drug have been conducted as per the WHO guidelines.Results:Unique arrangement of the vascular bundle in mid rib region is observed. Aqueous and alcoholic extracts showed the presence of alkaloids, phenols, tannins, and flavonoids.Conclusion:The findings of this study will be helpful in the identification of Dhataki leaf.
