Macrotyloma uniflorum (Lam.) Verdc. (family Fabaceae) is traditionally important pulse used for kidney stone degradation, cold,cough, asthma and in bronchial issues. It is well reported for the antilithiatic activity and nutritional profiling but no attempt has been made to find out the mechanism and nutrient responsible for the activity in its seed decoction. Therefore, lead high altitude variety responsible for the highest nutrient content and antilithiatic activity was selected for the study. Boiled spray dried extract (M1), lead fractionation (Spray dried residual water fraction: M2), and crude powder extract (M3) were nutritionally profiled using proximate composition analysis, Atomic absorption spectroscopy (minerals and trace elements), Ion exchange chromatography (carbohydrate analysis) and NMR spectroscopy (polar and non polar metabolite analysis). These extracts were also screened for the antilithiatic activity and found significantly important. M1 showed more activity than M3. Further, boiled extract was fractionated with different polarity of solvents (hexane, chloroform, n-butanol, residual water extract). All fractions and reference standard (cystone) were screened for the antilithiatic activity. M2 showed highest activity followed by ethyl acteate while hexane and chloroform did not show any activity in comparison to standards. Thus, lead fraction and market reference standard (cystone) were validated for the presence of nutritional components. Moreover, the selected nutritional components were individually and in combinations screened for the activity which revealed that kidney stone degradation was due to the synergetic action of components than the individual. The results clearly pave a way that Macrotyloma uniflorum is best for combating with malnutrition and kidney stone related problems.
