Standardization of Barg-e-neem (Azadirachta indica)
Abstract
The leaves of Azadirachta indica are commonly used medicinally in number of herbal products and herbal medicines The objective of the current study is to standardise Azadirachta indica leaves through qualitative and quantitative evaluation of various extracts. Physio-chemical analysis like determination of the pH value, determination of loss on drying, total ash value, acid insoluble ash value, different extractive values and presence of heavy metal was done on powdered leaves of the drug. The readings of the test sample were discovered to be within the suggested normal range. The refractive values of Thin layer chromatography of Azadirachta indica leaves alcoholic & hydroalcoholic extract also matched with control samples. The leaves of Azadirachta indica which were obtained from local market of khari baoli in Delhi are up to the mark and matched well with control values for the drug. Macroscopic evaluation of neem leaves was performed physically and the physical characteristics of sample found to match standard characters of Azadirachta indica plant.
