Steroidal alkaloids are usually classified with other alkaloids as the former are similar in structure but they resemble biosynthetically with terpenoids. The nitrogen is incorporated therein from ammonia or ammonium compounds. The application of nitrogen, therefore, could enhance the uptake of nitrogen and in turn the yield of Solasodine in the fruits of Solanum nigrum L. The correlation studies between the leaf-nitrogen content and the Solasodine content of the fruits of S. nigrum were made in three pot experiments. The nitrogen was estimated in leaves and Solasodine in fruits at different stages of growth using spectrophotometric methods. A statistical model for the prediction of the alkaloid at the early stages of growth (85 days after sowing) by estimating the nitrogen content in the leaves is hereby proposed. If leaf-N at early stage of growth predicts the low value of fruit-Solasodine, the corrective measures, like top- dressing or foliar spray could be employed immediately, for higher yield.
