Abstract For the first time, the phytochemical constituents of the leaves of Polyscias fruticosa (L.) Harms. cultivating in An Giang Province, Viet Nam were investigated and led to purify two new oleanane-type triterpenoid saponins, named polyscioside J (1) and polyscioside K (2) together with two known saponins, ladyginoside A (3) and chikusetsusaponin IVa (4) using variously chromatographic methods. Saponin (4) was reported for the first time from this species. Their structures were verified by IR, UV, HR-ESI-MS, NMR 1D and 2D experiments and compared with previous literatures.
