TL;DR: From a literature search for reports on the chemical constituents of these plants, most constituents were found to be quinone derivatives or other compounds with unsaturated carbonyl groups.
Abstract: Seventy-five Myanmar timber extracts belonging to 27 families were examined for their leishmanicidal activities. Some timber extracts had significant leishmanicidal activity, especially extracts of Millettia pendula, which exhibited the most potent activity (MLC 3.1 μg/ml, MIC 1.6 μg/ml). Other timber extracts showing potent activity included those from Cedrela serrata, Cedrela toona, Cordia fragrantissima, Calophyllum kunstleri, Dalbergia cultrate, Grevillea robusta, Haplophragma adenophyllum, Michelia champaca, and Tectona grandis. From a literature search for reports on the chemical constituents of these plants, most constituents were found to be quinone derivatives or other compounds with unsaturated carbonyl groups.

TL;DR: The chemistry of the limonoids was reviewed in this series by Dreyer (84); a more recent review is by Connolly, Overton and Polonsky (73), and taxonomic aspects have been reviewed recently by the present author.
Abstract: The purpose of this article is to review the chemistry of the limonoids isolated from plants of the natural order Meliaceae; limonoids from the Rutaceae and Cneoraceae are not included. The chemistry of the limonoids was last reviewed in this series by Dreyer (84); a more recent review is by Connolly, Overton and Polonsky (73). Taxonomic aspects have been reviewed recently by the present author (199), and chemistry and phyto-chemistry have been discussed at a recent meeting (81). The present article sets out to review advances in limonoid chemistry since the last review in this series (84); the tables however are intended to be comprehensive.

TL;DR: Diploid and polyploid forms of Ambrosia dumosa Gray have been found to differ markedly in chemical constitution, and the only identifiable lactonic constituent that is found in both forms is parthenolide.
