The N-oxide of the alkaloid dihydrocorynantheol (21) has also been mentioned as a natural product from the leaves of Mitragyna parvifolia (Roxb.) Korth. however, it was detected only by mass spectroscopy and no further evidence for the structure has been given (31).

Studies on Helietta parvifolia. In the northern arid region of Mexico, Rovalo e al. (23) carried out a study of the potential uses of Helietta parvifolia. They demonstrated that the essential oil of Helietta acts as a fungicide upon Penicillium, Rhlzopus, Fusarlum, and Aspergillus and also acts as an insecticide upon Anastrepha ludens (fruit fly). The allelopathic potential of Helietta leaves was demonstrated upon a common weed Convolvulus arvense.

From the plant Agathis robusta a group of labdane isomers at C-13 have been isolated and related to 13-e/n-manool after interconvertion using lithium in diaminoethane [110]. The Hymenaea species, i.e H. ablongifolia and H. parvifolia, have been studied and enantiopinifolic acid as well as guamaic acid have been isolated, while enantio-13-ep/-labdanolic acid has been isolated from Trachylobium verrucosum [111].

The genera Mitragyna and Ourouparia (Uncaria) (Rubiaceae) flourish in widely distributed tropical and subtropical regions. Several Mitragyna species that are large trees indigenous to West Africa, Southeastern Asia, and the Philippines find commercial use in the timber and paper industries. The leaves of M. speciosa Korth. are chewed as a narcotic in Siam, and, in common with leaves of M. parvifolia Korth., enjoy an undeserved reputation as a cure for opium addiction. In West Africa the bark of M. africana Korth. is used as a febrifuge. 

The occurrence of alkaloids in Mitragyna species was first reported by Hooper, who isolated a crystalline alkaloid in 0.15% yield from the leaves of M. parvifolia (1) this alkaloid was not named and has not since been reinvestigated. The leaves of M. speciosa contain the amorphous alkaloid mitragynine, mp 105°-115° (2, 3), while the bark contains mitraspecine, C23H30N2O5, mp 244°-245°, [a]ff° -59.15° (4, 5). A third base, giving an amorphous picrate, mp 123°-127°, is also present, but this has not been studied further, since no crystalline derivatives could be obtained (6). The alkaloid mitraphylline, C21H24N2O4, mp 270°,... 

Because most elms are susceptible to so many insects and diseases, you might want to avoid using them in the landscape. If you do decide to grow elms, consider planting lacebark elm (U. parvifolia), which is more resistant to Dutch elm disease and elm leaf beetles. Plant elms in spring or fall as bare-root or balled-and-burlapped trees. Full sun and well-drained soils are best.
