Phenolic compounds from the stem bark of Erythrina orientalis and their cytotoxic and antioxidant activities
Two prenylated pterocarpans, phaseollin (1), shinpterocarpin (2) together with flavonoids, 4’-O-methyl licoflavanone (3), alpinumisoflavone (4), 8-prenyl daidzein (5), have been isolated from the stem bark of Erythrina orientalis. The structures of these compounds were determined based on UV, IR,...

| الملخص: | Two prenylated pterocarpans, phaseollin (1), shinpterocarpin (2) together with flavonoids, 4’-O-methyl
licoflavanone (3), alpinumisoflavone (4), 8-prenyl daidzein (5), have been isolated from the stem bark of Erythrina orientalis. The structures of these compounds were determined based on UV, IR, HRESIMS, 1D and 2D NMR data. Compounds 1–5 were evaluated for their cytotoxic properties against P-388 cells, their IC values 2.55, 2.43,17.98, 4.31, and 5.82 µg/mL, respectively. Compounds 1, and 5 exhibited very high antioxidant activity against
DPPH radical scavenging. |
