“…The response of each compound was normalized to the response of an internal standard (9:0 ME or 15:0 ME), which was added to the sample at the constant concentration of 100 mg L −1 . The concentrations of individual FAs in each sample were converted to percentage contributions of the total FAs [22,23].…”

Fatty Acids from Paracentrotus lividus Sea Urchin Shells Obtained via Rapid Solid Liquid Dynamic Extraction (RSLDE)

Sea urchins (Echinodermata, Echinoidea) are good a source of bioactive compounds belonging to different classes of natural substances. The edible Mediterranean sea urchin Paracentrotus lividus is a renowned animal model for study in different fields of biology, but it is intensively harvested for high commercial value due to the delicacy of its gonads. Most studies have focused on the composition and the nutritional value of P. lividus gonads (the edible part), but little interest has been taken in the other body parts, such as the shells and spines, which are generally considered waste material. The purpose of this study was to obtain an extract from sea urchin shells, with a green methodology of extraction, and to characterize the lipophilic components for potential applications. The shells of P. lividus were extracted via a very well performing technology based on rapid solid liquid dynamic extraction (RSLDE) implemented via an automated device (Naviglio Extractor®). The obtained extract shows the presence of fatty acids and their esters (methyl, ethyl and 1-glycerol esters). Gas chromatography-mass spectrometry (GC-MS) measurements were used to determine fatty acid abundance in the chromatographic fractions of the extract. Arachidonic acid (ARA), 5,8,11,14,17-eicosapentanoic acid (EPA), and 11-eicosenoic acids and their esters are the most abundant components. The presence of many polyunsaturated fatty acids (PUFA) in the extract, even in low percentages allows a future application in nutrition or medical use.

“…Azelaic acid was the only compound identified to be exclusively produced by M. phaseolina PE35 grown in the presence of the host tissue. This dicarboxylic acid was recently detected in cultures of Neofusicoccum vitifusiforme, a fungus frequently associated to Botryosphaeria dieback of grapevine [40]. Azelaic acid has antimicrobial and anti-inflammatory properties finding application in the treatment of skin diseases.…”

In the course of investigations on the role of secondary metabolites in plant-microbe interactions, the production of secondary metabolites by Macrophomina phaseolina isolates from Eucalyptus globulus, was studied. This fungus is responsible for several plant diseases which affect crop productivity and industry. Although secondary metabolites may play a role in disease development, there are very few reports on M. phaseolina metabolomics and, as far as we know, isolates from eucalypts have not been investigated for secondary metabolites production. In the present paper, metabolites typical of fungi, from the family Botryosphaeriaceae, were identified for the first time as products of M. phaseolina. Furthermore, the isolate under examination was grown in the presence and absence of host stem tissue, and metabolite profiles were compared. Five products are reported for the first time in this species and azelaic acid was exclusively produced in the presence of eucalypt stem. Finally, phytotoxicity and cytotoxicity tests of culture filtrates and crude organic extracts were also performed. Key Contribution: Lipophilic metabolites produced by M. phaseolina might play a role in the plant-fungus interactions responsible for serious diseases of E. globulus.

“…Diverse species, such as Neofusicoccum australe, Neofusicoccum luteum, Neofusicoccum parvum, and Neofusiccocum vitifusiforme, have been isolated from grapevine (Vitis vinifera) and shown to be pathogenic to this host [15][16][17][18][19][20][21][22][23]. In fact, a long list of secondary metabolites has been identified from these strains and the structural variability might be associated with the role of these compounds in the grapevine diseases.…”

“…Fatty acids are essential storage molecules and the starting material for the synthesis of many secondary metabolites [39]. Some long chain fatty acids and their esters ( Figure 3) have been detected in culture extracts of strains of N. vitifusiforme and N. parvum [23,34]. Particularly relevant is the finding of linoleic acid (12) as a product of species of Neofusicoccum isolated from grapevine [23].…”

Secondary Metabolites Produced by Neofusicoccum Species Associated with Plants: A Review

The genus Neofusicoccum is comprised of approximately 50 species with a worldwide distribution and is typically associated with plants. Neofusicoccum is well-known for the diseases it causes on economically and ecologically relevant host plants. In particular, members of this genus are responsible for grapevine diseases, such as leaf spots, fruit rots, shoot dieback, bud necrosis, vascular discoloration of the wood, and perennial cankers. Many secondary metabolites, including (−)-botryoisocoumarin A, botryosphaerones, cyclobotryoxide and isosclerone, were identified from species of Neofusicoccum and their structural variability and bioactivities might be associated with the role of these compounds in the fungal pathogenicity and virulence. In this review, we summarize the secondary metabolites from Neofusicoccum species focusing on the role of these compounds in the interaction between the fungus and host plant.
