VARIABILITY IN PRIMARY METABOLITES IN SOME TUBEROUS MEDICINAL PLANTS FROM THE SITAMATA WILDLIFE SANCTUARY, PRATAPGARH (RAJASTHAN)

Abstract
Primary metabolites such as total chlorophylls, carotenoids, proline, osmotic potential, total sugars, phosphorus and crude protein are important for plant growth, development and their reproductions. These are simple molecules synthesized by plants, generally do not possess therapeutic as such but essential for the life of plants, which contain high-energy bonds and used for the biosynthesis of secondary metabolites. Three tuberous medicinal plants, viz Arisaema tortuosum (Wall.) Schott, Chlorophytum tuberosum Baker. and Curculigo orchioides Gaertn. are selected for the present study. A. tortuosum is a tuberous herb which is mainly used in snake-bite and considered as anthelmic, anti-nematodal, anti-inflammatory, etc. The roots of C. tuberosum and C. orchioides plant roots are considered as aphrodisiac. Experiments on primary metabolites were conducted during different months to find out the monthly variability in accumulation of these products. In A. tortuosum and C. orchioides, the maximum amount of total chlorophylls and total sugars were obtained during September. C. tuberosum exhibits less variability in all products during different months.
