Steroid and terpenoid constituents of 3 species of genus Phytolacca have been examined by TLC. All contained ${\alpha}$-spinasterol, its glucoside and acylated glucoside, jaligonic acid and its methylester, esculentic acid and its methylester, and 10 phytolaccosides. Jaligonic acid was the major free triterpenoid and phytolaccoside E was the major saponin in all plants. Bayogenin, oleanolic acid, spergulagenic acid, acinosolic acid, hederogenin, and their derivatives contained in other Phytolacca spp. were not found in these plants.
