Growth-inhibitory activities of selected natural benzofurans (4-9), trans-cinnamic acid derivatives (10-13), chromene compounds (14 and 16), and some semisynthetic derivatives were determined in last instar larvae of Tenebrio molitor via topical administration in Me2CO. The mast inhibitory of the tested compounds were 3-gamma,gamma-dimethylallyl-p-coumaric acid (10) and the benzofuran derivative 12-(p-cumaroyloxy)-tremetone (5), the former compound acting on the pupae and the latter on the last instar larvae. Several developmental deficiencies were observed, and some structure-activity relationships are discussed.

The present invention refers to achemical process for separation of different kinds of substances which are present in Brazilian propolis, by means of HPLC and GC-MS combined techniques. This provided a process for a HPLC separation which is able to identify the majority components of the propolis sample by using a suitable analysis software for this end.
