Cinnamomum rupestre Kosterm. (Lauraceae) is an endemic species in the Philippines originally discovered in Palawan [1], while Cinnamomum nanophyllum Kosterm. is a widespread endemic species in the country. In Cebu, the local people collect and prepare the leaves and the bark as a decoction for relief of stomach and abdominal ailments. There are no reported chemical and biological studies on C. rupestre and C. nanophyllum. These are two of the 21 species of Cinnamomum found in the Philippines, of which 16 are known to be endemic [1]. This study was conducted as part of our research on the chemical constituents of Cinnamomum species found in the Philippines. We earlier reported the isolation of eugenol and safrole from the bark, polyprenol from the leaves, and trilinolein from the roots of Cinnamomum cebuense [2].

Silica gel chromatography of the dichloromethane (DCM) extract of the bark of C. rupestre afforded 4'-hydroxy5,7,3'-trimethoxyflavan-3-ol (1),...
