Species belonging to the Michelia genus are arboreous plants growing in temperate zones of oriental India, southern China, Malaysia, and Indonesia. Various chemical constituents isolated from different species of the genus Michelia include aporphines, oxoaporphines, steroids, benzenoids, and terpenoids. The important biological activities of constituents isolated from Michelia are anticancer, antiplasmodial, and antibacterial activities . Less known species, as Michelia crassipes Y.W. Law, are used as ornamental plants and to obtain essences . M. crassipes, a small evergreen shrub tree in Magnoliaceae, is a great ornamental plant with fragrant and dark purple flowers. It became a useful cross breeding germplasm resource. Field observation in Changsha (China) indicated that its flowers started blooming in late March and continued into early May for about 50 days . To further understand the chemotaxonomy of the Michelia species [3, 4, 5, 6, 7, 8, 9, 10, 11], M. crassipeswas...
