“…Furthermore, Michelia spp. has been used by indigenous peoples of India for the treatment of cancer and abdominal tumors (Chen et al, 2008). The presence of phenolics was detected in callus from decoated seed fragments, indicating its competence for synthesis of secondary metabolites (Iyer et al, 2005).…”

Michelia champaca callus was induced from axillary bud explants cultured onto Murashige and Skoog (MS) basal medium supplemented with different concentrations of auxins (IAA and 2,4-D) and cytokinin (BAP) as plant growth regulators. It was observed that callus of M. champaca could be induced on MS media supplemented with 0.0-2.0 mg/l IAA, 0.0-2.0 mg/l 2,4-D, and 0.0-2.0 mg/l BAP, respectively. All growth regulators that were used in this study are capable of inducing callus from explants. 0.10 mg/l IAA and 0.10 mg/l 2,4-D were found to be the suitable concentrations for the induction of callus. The survival rate of explants in the media supplemented with IAA was found to be 81%. MS Media supplemented with different concentrations of BAP combined with IAA and 2,4-D were tested for callus proliferation. The callus growth showed good response to all growth regulators combinations tested in this study, except the combination BAP/IAA with 0.2/0.10 mg/I which exhibited low response with dark brown callus. The combination 2.00 mg/l BAP with 0.50 mg/l IAA and all the combinations of BAP with 2,4-D showed the highest rate of callus proliferation with cream colour. This study suggests that auxins along with cytokinins have a critical role on the callus and shoot proliferation of this plant.

“…The bark is used for the treatment of fever, syphilis, gonorrhoea and malaria, and the white fragrant flower is used traditionally as an abortive agent (Asaruddin et al, 2003). In previous studies, we found four aporphines, two oxoaporphines, three sesquiterpene lactones, one amide, one lignan, one neolignan, three benzenoids, two steroids, three aliphatic compounds and two chlorophylls from M. alba (Chen et al, 2008). As part of our continuing investigation into the phytochemical and bioactive compounds of Magnoliaceous plants (Lo et al, 2004), a new chlorophyll, michephyll A (10), together with 9 known compounds, (À)-N-formylanonaine (1) (Bentley, 1999), (À)-oliveroline (2) (Perez, Saez, Blair, Franck, & Figadere, 2004), (þ)-nornuciferine (3) (Cava, Rao, Douglas, & Weisbach, 1968), lysicamine (4) (Zhang et al, 2002), (þ)-cyperone (5) (Sonwa & Konig, 2001), (þ)-epi-yangambin (6) (Chao et al, 2002), ficaprenol-10 (7) (Aoki, Matsuo, Suga, & Oiita, 1997), pheophytin a (8) (Walkera, Squiera, Hodgsonb, & Keelya, 2002) and aristophyll C (9) (Chan, Leu, & Wu, 1999) were obtained via chromatographic fractionation of the methanolic extract of the leaves of this plant.…”

(-)-N-Formylanonaine (1), (-)-oliveroline (2), (+)-nornuciferine (3), lysicamine (4), (+)-cyperone (5), (+)-epi-yangambin (6), ficaprenol-10 (7), pheophytin a (8), aristophyll C (9) and michephyll A (10) were isolated from the leaves of Michelia alba DC (Magnoliaceae). Among them, 10 is a new compound. The structures of these compounds were characterised and identified by spectral analyses. We have also presented the antioxidation activity of 10.

“…Recently, we reported four aporphines, one oxoaporphine, two amides, one lignan, two neolignans, one benzenoid and two steroids from the stems of this plant (Lo et al, 2004). To further understand the chemotaxonomy of the Michelia species (Chen et al, 2008a(Chen et al, , 2008bLo et al, 2004;Lo, J. Huang, L. Huang, & Chen, 2010;H. Wang, Lo, Huang, Y.
