Microscopic Illustration of Pelargonium x hortorum (Geraniaceae)
Asian Journal of Research in Botany,
For identification of a crude drug, there are several parameters which standardize it for sure. Microscopic features describe a crude drug very well. Chances of adulteration are very common due to morphological similarities in different species of drugs and to avoid such confusions, standardization via microscopy helps to create a valuable profile of a given crude drug. Involving different parts of plant drug in microscopy viz leaves, stem, roots and flower etc. helps a lot in identifying the original drug. Transverse section of different parts of plant, powder microscopy and determination of leaf constants like stomatal number, stomatal index, vein islet number, vein termination number and palisade ratio of Pelargonium x hortorum describes the basic features of the drug and authenticate it as the original one.
