In 1991, McChesney and El-Feraly described the isolation and structural elucidation of 3-formyl-6-methoxycarbazole (97) from the roots of C. lansium (23). The roots of this ornamental tree are used in traditional medicine in Taiwan to treat bronchitis and malaria (23). In 2005, Franzblau et al. isolated the same natural product from the stem bark of Micromelum hirsutum (103). They reported that 3-formyl-6-methoxycarbazole (97) shows in vitro anti-TB activity against the H37RV strain of Mycobacterium tuberculosis. 

The compounds and their sources are listed in chronological order of isolation in Table I. The majority of the Rutaceae oxazoles have been isolated from the Old World genera Halfordia, Aegle, Aeglopsis, and Micromelum Amyris is the...

Taxonomically the Rutaceae carbazole alkaloids are of interest as they have been isolated exclusively from four closely related genera GlycosmiSf Murraya, Clausena and Micromelum)... 

Carbazole alkaloids are found in the genera Clausena, Gly-cosmis, Micromelum, and Murray a of the Rutaceae. There is a single report from the genus Ekebergia of the Meliaceae (Bhattacharyya and Chakraborty, 1987 Chakraborty and Roy, 1991).

Phlorizin is a dihydrochalcone. Apart from its common occurrence in rosaceous trees, and especially in the root bark, it is otherwise reported as occurring only in Micromelum teprocarpum, a relative of Citrus. Although present in the seeds, shoots, and leaves of apples, it appears to be entirely absent from the flesh—a fortunate fact in view of its poisonous character.
