In developing nations, the healthcare sector is mainly dependent on medicinal plants which are the major source of curative molecules to treat various diseases. Rheum emodi Wall. The therapeutic benefit of Rheum emodi exMeisn is well known in the Indian system of medicine, the modern pharmaceutical industry, and the local system of medicine, leading to excessive and illegal extraction and habitat loss. The species is now limited to a few pockets and faces extinction. Keeping this in view, there is needed to study the different sites of R. emodi to get more information to take up their conservational strategies. The present study deals with the variation observed in the number of phyto-constituents and soil NPK content in the plant R. emodi at two different altitudes; Baniyakund (2582 m) and Tungnath (3460 m) representing lower and higher altitudes respectively. The sample result reveals that total nitrogen content and total organic carbon content increase with altitude while available nitrogen content and potassium content decrease with increasing altitude. The result reveals that the amount of total phenolic content, and overall alkaloid content increase with increasing altitudes. To a certain level, this study gives proof that altitude is one of the environmental factors that can influence the number of phytochemicals.
