Abstract
In recent years biologically active compounds isolated from insects call special interest of drug researchers. According to some Polish etnopharmacological observations, secretion from the grasshopper's abdomen (Orthoptera family) is believed to speed up the process of wound healing.In the present work we focused on determination of main components of the lipid fraction of material from grasshopper abdomen using GC–MS/MS. Samples were qualitatively analyzed using gas chromatography coupled with mass spectrometry. Both liquid–liquid extraction and solid-phase extraction pretreatment methods were used to concentrate and fractionate the compounds from the insect. In the derivatized fractions ca. 350 compounds were identified, including substances of known biological activity. The potential agents affecting wound healing have been indicated.A set of compounds characteristic for all the studied Chorthippus spp., have been identified. Data analysis revealed different lipidomic profiles of grasshoppers depending on the insects origin and collection area.
