A new daphnane diterpenoid, rediocide F (1), was isolated together with three known compounds, rediocides A (2), C (3) and E (4), from the hexane extract of Trigonostemon reidioides roots by bioassay-guided fractionation for acaricidal activity on Dermatophagoides pteronyssinus, Thai common house dust mite. The structure of rediocide F (1) was established as the demethyl analog of rediocide C (3) on the basis of spectral analysis. Compounds 1—4 exhibited potent activity against D. pteronyssinus with respective LC₅₀ values of 2.53, 0.78, 5.59 and 0.92 μg/cm².
