“…The compounds 1-pentadecene, 2-ethyl-pbenzoquinone, limonene, and 1-tridecene identified in the extracts of U. dermestoides have been previously reported in studies to determine the chemical characteristics of the defensive secretions and sex-specific pheromones of U. dermestoides (17,18). The monoterpene hydrocarbons alpha-pinene, alpha-terpinene, phellandrene, and dimethylquinones have been reported in the defensive secretions of some Australian tenebrionid beetles (19,20).…”

Background: In traditional medicine of Central and South America, the tenebrionid beetle Ulomoides dermestoides is used as an a phrodisiac, for the treatment of inflammatory diseases and cancer. Recently was reported cytotoxic and genotoxic properties of non-polar extract of U. dermestoides; also anti-inflammatory and immunomodulatory activity of aqueous whole body extract of beetle was reported, it suggests the existence of components with potential pharmacology use. On the other hand, it is necessary to identify those polar and non-polar extracts of U. dermestoides with anti-irritant properties for the membranes and blood vessels, which will be used in subsequence biological test and clinical assays. Objectives: The purpose of this research was to identify the chemical composition of methanolic and hexanic extracts of U. dermestoides, and to assess their anti-irritant capacity. Methods: The extracts were obtained from adult beetles of U. dermestoides. The chemical composition of the extracts was determined by gas chromatography-mass spectrometry (GC-MS) and the anti-irritant effect of each extract was evaluated by means of a modified assay of irritation of the chorioallantoic membrane (CAM) of fertilized chicken eggs (HET-CAM); the results were expressed as irritation index (IR). Results: Six common compounds were identified in both extracts: limonene, myristic, palmitic, estearic, oleic, and linoleic fatty acids. But in the alone methanolic extract were found: 1-pentadecanol, alpha-pinene, beta-phellandrene and alpha-terpinene, whereas in the hexanic extract were found: 2-methyl-p-benzoquinone, 2,4-dihidroxy-1-ethylbenzene, 2,5-dimethylquinone, saturated and unsaturated hydrocarbons and alcohols. The methanolic extract of U. dermestoides showed potential anti-irritant effect in the HET-CAM test (IR = 3.09 ± 0.11), similar to that observed with Nimesulida (IR = 2.05 ± 0.14), a non-steroid anti-inflammatory drug (NSAID) used as positive control for irritation inhibition reaction. The hexanic extract did not show anti-irritant capacity. Conclusions: The results demonstrated the anti-irritant effect of the methanolic extracts of U. dermestoides that could be attributed to compounds with anti-inflammatory activity as oleic acid and limonene.

“…A few isomers of the alkenes provisionally identified in our analyses have been implicated as semiochemicals or semiochemical components for beetles and honey bees. For example, 1‐undecene is a sexual pheromone for Bruchinae (Bruce, Martin, Smart, & Pickett, 2011) and an attractant for Carabidae (Evans, 1988); 1‐tridecene is a sexual pheromone for Tenebrionidae (Martins, Zarbin, & Almeida, 2010); 1‐pentadecene is an aggregation pheromone for Tenebrionidae (Martins et al, 2010) and an attractant for Carabidae (Evans, 1988); and cis ‐jasmone is an attractant of Scarabaeidae (Dötterl, David, Boland, Silberbauer‐Gottsberger, & Gottsberger, 2012; Loughrin, Potter, & Hamilton‐Kemp, 1998), and is also found in the floral scent of X ylopia benthamii , which is pollinated by Nitidulidae and Staphylinidae (Jürgens, Webber, & Gottsberger, 2000). Likewise, a few isomers of the alkenes retrieved in our analyses have been reported as semiochemical components for honey bees, viz.…”

Artabotrys comprises a species-poor early divergent grade (EDG) and a main species-rich clade ("main Artabotrys clade," MAC). All members of the MAC exhibit a remarkably well-conserved floral Bauplan characterized by a tightly enclosed floral chamber with an elaborate rim between the inner petal blade and claw. Conversely, EDG resembles the sister genus Xylopia in lacking the inner petal rim, with one species (Artabotrys brachypetalus) bearing petals that lack the distinction between blade and claw altogether. The floral phenology and pollination ecology of two exemplar species-Artabotrys brachypetalus from the EDG and Artabotrys blumei from the MAC-are compared, including assessment of effective pollinators and their activity patterns, scent chemistry and thermogenesis. Our study revealed that Artabotrys blumei exhibits abbreviated anthesis (c. 27 hr), with a floral phenology and morphology that are clearly consistent with pollinator trapping, and may be pollinated by small beetles. Artabotrys brachypetalus has a typical anthetic duration (c. 45 hr), lacks a pollinator trapping mechanism, and is pollinated by honey bees and curculionid beetles. The "xylopioid" traits of the EDG are likely to be plesiomorphic, whereas the tightly enclosed floral chamber is likely to be apomorphic for the MAC and functionally significant in trapping pollinators.

“…Consistent with earlier studies of other Tenebrionids, the chemical constituents of the defensive secretions of U. dermestoides were determined to contain 1,4-benzoquinones, and long-chain 1-alkenes (11, 127-129 in Fig. 20 ) along with other, minor constituents, including limonene ( Eisner et al ., 2005 ; Francke and Dettner, 2005 ; Villaverde et al ., 2009 ; Martins et al ., 2010 ). Tests of extracts from U. dermestoides and closely related species, along with some of the individual compounds that make up the defensive secretions, have shown a wide-range of bioactivities, including cytotoxicity ( Crespo et al ., 2011 ), anti-diabetes ( Jasso-Villagomez et al ., 2018 ), anti-senility ( Yan et al ., 2009 ), anticoagulatory ( Wu et al ., 1996 ), and anti-asthma/anti-inflammatory (Wahrendorf and Wink, 2006; Santos et al ., 2010 ).…”

Traditional Chinese medicine (TCM) was the primary source of medical treatment for the people inhabiting East Asia for thousands of years. These ancient practices have incorporated a wide variety of materia medica including plants, animals and minerals. As modern sciences, including natural products chemistry, emerged, there became increasing efforts to explore the chemistry of this materia medica to find molecules responsible for their traditional use. Insects, including beetles have played an important role in TCM. In our survey of texts and review articles on TCM materia medica, we found 48 species of beetles from 34 genera in 14 different families that are used in TCM. This review covers the chemistry known from the beetles used in TCM, or in cases where a species used in these practices has not been chemically studied, we discuss the chemistry of closely related beetles. We also found several documented uses of beetles in Traditional Korean Medicine (TKM), and included them where appropriate. There are 129 chemical constituents of beetles discussed.
