One of the most widely used herbs in Ayurvedic medicine is Ashwaghanda, Withania somnifera, a shrub commonly found on the Indian subcontinent. As this plant is increasingly becoming a popular adaptogenic in the western world, analytical methods for its identification and quality control are in demand. Thus, a HPLC method for the determination of withaferin A and withanolide D was developed. The system was successfully used to investigate the presence of the markers in different W. somnifera plant parts as well as to analyze their content in market products.
