ARCINIEGAS, Amira et al. Chemical Constituents of Psacalium sinuatum. J. Mex. Chem. Soc [online]. 2009, vol.53, n.4, pp.229-232. ISSN 1870-249X.

A chemical study of Psacalium sinuatum afforded the furanoeremophilane decompostine, the modified eremophilanes: cacalol, cacalol acetate, dehydrocacalol, maturinin, cacalohastin, dehydroca-calohastin, adenostin B, cacalone-epi-cacalone mixture, dimaturin, adenostylide, radulifolin F, and epi-radulifolin F, in addition to hyperin, sucrose and a mixture of sitosterol-stigmasterol. Extracts and isolated compounds were tested for anti-inflammmatory activity. The hexanic extract of root showed a dose dependent activity (IC₅₀ 0.20 mg/ear).

Keywords : Psacalium; Asteraceae; Senecioneae; Tussilagininae; Modified Eremophilanes; Anti-inflammatory Activity.
