Description

Appendix 2 (continued on next page). List of identified volatile compounds emitted by flowers of Xylopia aethiopica Dunal (A.Rich) and Uvariodendron molundense (Diels) R.E.Fr. (Annonaceae). Compounds are sorted by chemical family. Numbers indicate the percentage of each compound in the floral scent, based on the peak areas in Mass Spectrometry analyses. Compounds that could not be identified are listed as “unknown compounds”. When their chemical structure provides enough information, they are assigned to a chemical family and listed as unknown within that family.
