The genus Michelia (Magnoliaceae) consists of about 30 species. One of the species is native to Taiwan. Michelia compressa var. formosana is an evergreen tree, especially distributed in Taiwan, Japan, and Ryukyu Islands. Michelia species have been used by indigenous peoples for the treatment of cancer. For example, Michelia champaca has been used in India for the treatment of abdominal tumors and M. hypoleuca and M. officinalis for carcinomatous sores and leukemia, respectively, in China [1]. There is only one paper describing a constituent (ceryl alcohol) from the leaves of M. compressa [2]. Recently, we reported four aporphines, one oxoaporphine, two amides, one lignan, two neolignans, one benzenoid and two steroids from the stems of this plant [3]. In continuation of a program studying chemotaxonomy and biologically active components from Magnoliaceous plants [3–7], four aporphines, (–)-anonaine [8], (–)-N-acetylanonaine [9], (–)-N-formylanonaine [10], (–)-N-acetylnornuciferine [11]; two oxoaporphines, liriodenine [8], oxoxylopine [12]; one lignan, (+)-syringaresinol [13]; two amides, N-trans-feruloyltyramine [14], N-cis-feruloyltyramine [15]; seven benzenoids, 4-hydroxybenzaldehyde [16], 4-hydroxybenzoic acid [16], methylparaben [16], syringaldehyde [16], syringic acid [16], eugenol [17], ferulic acid [16]; two chlorophylls, pheophorbide a [18], aristophyll-C [19]; and two steroids, β-sitosterol, stigmasterol [20], are isolated from the leaves of M. compressa. In addition to (–)-anonaine, liriodenine, (+)-syringaresinol, N-trans-feruloyltyramine, N-cis-feruloyltyramine, β-sitosterol, and stigmasterol, all of these compounds were isolated for the first time from this source [21–27].
