Effect of Green House Condition on Development of Soybean Seed Saponins, Sphingolipids, and Phytosterols Concentrations and Compositions

This study investigated the effect of green house conditions (temperature and soil moisture) on soybean [Glycine max (L.) Merr.] seeds bioactive compound concentrations. The analyses included plant characters and bioactive compounds contents. There were a good relationship between maturity date and total sphingolipids. Jack and Queen, among the latest and earliest had maturing entries, respectively. Jack had the highest concentrations of total saponins and total phytosterols. Imari had the lowest total saponins, total sphingolipids, and total phytosterols concentrations but Queen had the lowest total sphingolipids among all cultivars. Each cultivar had specific characters and maintained its level along different analyses. Under controlled conditions, sphingolipids levels had changed more than saponins and phytosterols.
