Chemical constituents from Vietnamese mangrove Calophyllum inophyllum and their anti-inflammatory effects

In a search for anti-inflammatory activity in resources from Vietnamese mangroves, we found that a methanolic extract from the leaves of Calophyllum inophyllum (CIL) showed significant anti-inflammatory effects in vitro. Using various chromatographic techniques, we subsequently isolated 12 compounds (1–12) from a methanolic extract of CIL, including two novel compounds (1–2). The inhibitory effects of these compounds on...
