title: A comparative analytical study of Prasarani [Merremia tridentata Hallier. f. and Paederia foetida Linn].
abstract: Prasarani is one of the drugs used in Vata Rogas such as Amavata, Avabahuka, etc. Among the different source plants of Prasarani, the plant Merremia tridentata Haller.f. is mostly used in South India and the plant Paderia foetida Linn. in North India, hence taken in the present work for comparative analytical study. It was observed that there is a common constituent (having 350 mm absorbance maxima) present in both the drug samples indicating that both works on a similar disease. It was also found that the whole plant powder sample of P. foetida has more number of constituents than that of M. tridentata which indicates P. foetida may have a better efficacy than M. tridentata.
