Forest resources in the Western Ghats of India are facing several threats including habitat destruction, forest fragmentation, regeneration problems, illegal and selective felling of commercially important trees as well as extraction of non-wood medicinal forest products. This has instigated a recent trend to adulterate/ substitute the existing resources to satisfy the demand of the growing industries. Adulteration/ substitution compromises the therapeutic value and are extremely difficult to authenticate using taxonomic tools. The ability to track and authenticate forest resources of economic value is thus critically essential for the effective management of the natural resources and appropriate regulation of the trade. DNA barcoding, as facilitated by the Consortium for the Barcode of Life (CBOL), is the process of identification of a species using short conserved standard set of gene regions and is proposed to precisely identify species at all the lifecycle stages. Developments over the last 10 years in the development of successful barcode even from dried and processed plant samples offer a promising molecular tool for the authentication of forest wood and non-wood forest produce and thereby to curb illegal and adulteration activities. In this paper, we demonstrate the potentialities of DNA barcodes to authenticate original timber species East Indian sandalwood (Santalum album) and red sandalwood (Pterocarpus santalinus) as well as Ayurvedic raw drugs in the Western Ghats of India from their market adulterants/ substitutes.
