Background: Homonoia riparia Lour. (Family: Euphorbiaceae) is an important medicinal plant in Indian and Chinese systems of medicine used in the treatment of various medical conditions like urolithiasis, renal problems, and inflammation. This is the first report on the pharmacognostical standardisation and phytochemical evaluation of whole plant of Homonoia riparia Lour. Objective: To establish the pharmacognostical and physicochemical standardisation parameters of whole plant of Homonoia riparia Lour. Materials and Methods: The plant was studied for the morpho-anatomical characters, standardisation parameters such as ash value, extractive value, fluorescence analysis, loss on drying, swelling index, foaming index according to Indian Pharmacopoeia and WHO guidelines. Phytochemical analysis was also performed by standard methods. Quantification of gallic acid in Homonoia riparia was carried out using HPTLC technique. Results: The detailed microscopy of root revealed the presence of cork, cork cambium, pericyclic fibres, thick walled parenchyma and starch granules. The distinguishing characters of stem are presence of sclereids, xylem, phloem, fibres. Leaf microscopy showed the presence of anomocytic stomata, bicollateral vascular bundles ensheathed by fibres. Rosette crystals are present in all the parts of the plant. Starch grains are abundantly present in root and stem but absent in leaves. Various physicochemical parameters were also determined. Phytochemical screening of the extract and HPTLC quantification of gallic acid was also performed. Conclusion: The present study provides pharmacognostical, physicochemical and phytochemical details of the whole plant of Homonoia riparia which are useful in laying down standardization and pharmacopoeia parameters.
