The Skyscraper Index, created by economist Andrew Lawrence shows a high level of correlation between skyscraper construction and the business cycle. Is this just a coincidence, or perhaps do skyscrapers cause business cycles? A theoretical foundation of “Cantillo...

this study was carried out to evaluate the in vitro and in vivo antifungal efficacy of essential oil and extracts derived from the flower and leaves of magnolia liliflora, respectively, against plant pathogenic fungi. the oil (750 μg disc-1) and various leaf extracts such as hexane, chloroform, ethyl acetate and methanol (1,500 μg disc-1) revealed promising antifungal effects against botrytis c...

From the ethyl acetate soluble fraction of twigs of Magnolia denudata (Magnoliaceae), seven new neolignan derivatives, 1-7, were isolated along with eighteen known lignan and neolignan derivatives, 8-25. The structures of the new neolignans were elucidated by means of spectral methods, especially by 1H-NMR and 13C-NMR spectra, and two dimensional NMR methods such as 1H-detected heteronuculear m...

In this study, eight endophytic fungi were isolated from the leaves, stems and roots of Michelia champaca. The isolates were screened and evaluated for their antifungal, anticancer and acetylcholinesterase (AChE) inhibitory activities. All of the extracts exhibited potent activity against two evaluated phytopathogenic fungi. Chemical investigation of EtOAc extracts of the endophytic fungus Coll...

Little is known about the ecology and demography of the genus Magnolia. Magnolia dealbata Zucc. is an endangered species endemic to Mexico. Two contrasting populations of M. dealbata (one from the grasslands and other from a secondary cloud forest) were studied. We asked the following questions: (a) Are size structure (diameter at breast height, DBH) and infrutescence production significantly d...
