Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2012, Vol 3, Issue 8
Abstract
Drug consists of nutgalls of Quercus infectoria (Family-Fagaceae), commonly known as “Mazuphal”. Standardization parameters like, physical constants, ash content, solvent residues, phytochemical screening, fluorescence and microscopical analysis were carried out for the quality, strength and purity of the drug. The present work is an also attempt to evaluate contamination parameters for safety of an herbal drug Quercus infectoria such as microbial contamination, aflatoxins, pesticide residues and heavy metals. Result revealed that the total ash content and acid insoluble siliceous matter were found 2.11% and 0.22% respectively in the drug. The extractive values were varies at different solvent at different condition. Loss on drying and pH at 25(ºC) were 9.97 and 6.1 respectively. Study revealed that total bacterial count and total fungal count were found to be within the permissible limit. Heavy metal like cadmium and mercury were not detected in the drug but arsenic (0.31 mg/kg) and lead (0.70 mg/kg) were found under permissible limit. Pesticide residue such as o, p- DDD, p, p- DDD, o p- DDE, p, p- DDE, o, p- DDT, p, p- DDT, α- Endosulfan, β – Endosulfan, Parathion, α- HCH, β- HCH, γ- HCH, δ- HCH was absent in the nutgalls.
