Evaluation of secondary metabolites in three tuberous medicinal plants during different months from south-eastern part of Rajasthan

Abstract

Arti Soni and Pawan K Kasera The present paper deals with variations in total alkaloid and phenol contents during different months (June-October) in three medicinally important tuberous plants, i.e. Arisaema tortuosum, Chlorophytum tuberosum and Curculigo orchioides from south-eastern part of Rajasthan. Secondary metabolites are organic compounds that are not are known to play a major role in the adaptation of plants to their environment, but represent an important source of active pharmaceuticals. Results revealed that peak concentrations of total alkaloids in A. tortuosum and C. tuberosum were observed during August, whereas during September in C. orchioides. However, total phenols in A. tortuosum, C. orchioides and C. tuberosum were reported during October, September and June, respectively.
