Medicinal plants are sources of unknown chemical substances with potential therapeutic effects. It is essential to know the proper use, curative dose concept and role of their active ingredients in current treatment system. The high cost of modern drug and inaccessibility of medicinal health care facilities in rural areas, compel the local people to rely on medicinal plants. Studies revealed that the use of drugs based on folk knowledge without any scientific screening is dangerous. The book covers wide information of methods to analyse, identify and determine the authenticity of the selected drug in herbal industry. The methods of analysis mentioned in the book help in quality control check of the crude drugs in future for maintaining quality, safety and reproducibility and act as a major tool for obtaining a qu...

According to Ayurveda it has stimulant, astringement, haemostatic aphrodisiac, diuretic, antidiarrheal, cardiotonic, emetic, demulcent, antidysenteric, al ternative and antipyretic properties 1. The roots of the plant also possess a number of medicinal properties. However there is a lack of data corresponding to the standardization and phytochemical profile of roots of the plant. Therefore the parameters related to physico-chemical properties like extractive values, ash values, loss on drying have been evaluated and were analysed as per WHO guidelines. Preliminary phytochemical screening was performed using standard chemical reagents. The preliminary phytochemical screening of the alcoholic extract extract validate d the presence of carbohydrates, glycosides, alkaloids, sterols, phenolics and tannins, saponins, flavonoids and amino acidsThe presence of different phytochem ical constituents were confirmed by performing TLC and HPTLC screening. TLC and HPTLC analysis revealed the presence of various phyto-constituents along with flavonoids, steroids and amino acids. HPTLC analysis revealed the presence of Quercetin, Kaempferol, Cholesterol a nd Glutamic acid. Detection was done under 254 and 366 nm. The data generated may be used as a diagnostic feature to ascertain the authenticity and quality of the crude drug.
