Two new triterpenoid glucosides, Heritiera A (1) and Heritiera B (2), and six known triterpenoid analogs (3–8) were isolated from Heritiera littoralis Dryand. Their structures were identified by comprehensive spectroscopic analyses and comparisons with the literature. The anti-inflammatory activity of the isolates from H. littoralis was evaluated using a lipopolysaccharide (LPS) stimulated RAW 264.7 cells model. The result showed that four triterpenoids exhibited potent anti-inflammatory activity. Among these compounds, compound 2 substantially inhibits the release of nitric oxide (NO) with an IC50 value of 10.33 μM. The triterpenoids from H. littoralis could be used as potential candidates for the development of new anti-inflammatory agents.
