Aim: The aim of the present study was to evaluate a poly herbal syrup (PHS) including; powder microscopy, preliminary phytochemical screening and stability studies.
Material and methods: Powder microscopy and other pharmacognostic parameters like length and width of starch grains, length of trichome, ash value, and extractive value of individual drugs were performed to confirm the authenticity. Preliminary phytochemical screening was done by standard procedure. Formulation stability was determined by measuring its density, particle size and viscosity.
Results: The individual drug of the formulation was authenticated based on the powder microscopy, and other pharmacognostical parameter coincided with standard values. The preliminary phytochemical screening showed the presence of various chemical constituents in the individual drug. Stability studies showed PHS formulations were stable.
Conclusion: The results of the present study can be used for the genuine identification of the plant from its adulterants and subsequent screening for potent bioactivity in polyherbal formulations.
