A limonoid, clausenolide‐1‐ethyl ether (1) and two coumarins, dentatin (2) andnor‐dentatin (3), were isolated fromClausena excavata. Limonoid 1 was obtained from the crude ethanol extract of the rhizomes and the roots but had not previously been isolated fromC. excavataand exhibited HIV‐1 inhibitory activity. Coumarins 2 and 3, with their structures related to an anti‐HIV‐1 substance, (+)‐calanolide A (4), were obtained from the crude chloroform extract of the rhizomes. Both induced toxicity to cells used in a syncytium assay for anti‐HIV‐1 activity. These compounds, 1–3, did not show any cytotoxic effect against KB and BC‐1 cell lines (IC50value > 20 µg/mL).
