摘要: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.
