This study aimed to investigate the chemical constituents of the twigs of Aglaia perviridis and their potential health benefits. A total of 29 triterpenoids, including eight previously undescribed dammarane triterpenoids, perviridisins A (1) and D-J (4-10), two unusual abeo-dammarane triterpenoids, perviridisins B (2) and C (3), and five unidentified nordammarane triterpenoids, perviridisins K-O (11-15), along with 14 known analogues (16-29), were isolated from the twigs of A. perviridis. Their structures with absolute configurations were elucidated based on a combination of extensive spectroscopic data analyses, chemical methods, electronic circular dichroism (ECD), Mo
