In recent years there is a spurt in the interest regarding survival of
traditional herbal drug medication. At the same time in the global
perspective, the authenticity, purity and standardization are important
aspects with respect to herbal drugs. As the name implies authenticity
relates to providing the materials is true and corresponds to right
identity. This book describes the chemotaxonomic markers including
organoleptography (color, taste, odor, appearance, texture, clarity),
morpho-palynology {macro and microscopic features based on light
microscope (LM) and scanning electron microscopy (SEM), leaf epidermal
anatomy (LM), chromatographic analysis (TLC)} and fluorescence quenching
(UV and IR analysis) used as an aid in the identification of genuine
source of herbal drugs. Because of gravity of problems like
adulteration, nomenclatural confusion, morphological similarities and
lack of knowledge about genuine source, these chemotaxonomic techniques
are of utmost importance for wider acceptance according to World Health
Organization (WHO).
