STEROID ALKALOID AND SAPOGENIN CONSTITUENTS OF SOLANUM LACINIATUM

Abstract

The leaves and stalks of Solatium laciniatum Ait grown in Egypt were found by isolation to contain the steroid alkaloid solasodine (25 R)–22 α N–spirosol–5–en–3β–ol (I) and two steroid sapogenins, diosgenin (25 D)–spirost–5–en–3β–ol (II) and chlorogenin (25 D)–5α–spirostane–3β–6α–diol (III).
