Abstract
Ethnobotanical survey plays a vital role for the discovery of novel crude drugs from reported medicinal plants. In folklore traditions the plant extracts or decoctions have been used to treat different diseases representing a basis of chemical entities but without knowledge of their nature. The present study was planned to conduct biochemical profiling of five indigenous medicinal plants of Cholistan desert of Pakistan to be used as potential chief constituents in the drug discovery practice. Qualitative phytochemical analysis of these plants confirmed the presence of various important secondary metabolites viz isoflavones, sesquiterpene lactones, phenolics, flavonoids and non-alkaloids. Methanolic extracts of Suaeda fruticosa and Solanum surattense showed significant antibacterial activities with mean halo diameters of 19.5 ± 0.3 mm and 14.8 ± 0.5 mm respectively, and inhibited the growth of Escherichia coli. Biochemical profiling of selected plants is reported for the first time. The methanolic extracts of Fagonia indica and S. fruticosa were found to have maximum numbers of phytochemicals. The occurrence of various bioactive compounds confirmed the studied plants against various diseases as local people of Cholistan desert still have a solid belief on herbal remedies for their elementary healthcare issues. Isolation of individual active constituents from each plant reported here may proceed to find some novel natural drugs. Key words: Medicinal plants; Cholistan desert; Biochemical profiling; Antibacterial activity; Secondary metabolites.
