Five new triterpenoids, serrulatins A–E ( 1 – 5 ), including two new artifacts, together with ten known serrulatins, were isolated from the edible leaves of Photinia serrulata after extraction and purification. Their structures were identified on the basis of spectroscopic methods including 2D NMR experiments. Compounds 1 and 3 are unusual ursolic triterpenoids characterized by the occurrence of a C(13)C(18) bond.
