There are two species of plant that grow flourishing all around Indonesia including in Banten and West Java which are Merremia vitifolia and Bidens pilosa. In this study we evaluate how these plants could be potentially used as natural preserver of fish product especially Auxis thazard, to inhibit the histamine formation, and to find out how this activity correlates to the substances in polar extract of B. pilosa flowers and M. vitifolia leaves. Liquid chromatography with tandem mass spectrometry (LC-MS/MS) and gas chromatography-mass spectrometry (GC-MS) were used to identify the substances of the plant’s part extracts. There are 27 chemicals in M. vitifolia extract and 14 chemicals in B. pilosa extract that have been detected. A triglyceride has been detected, isolated, and characterized by FTIR, 1H-NMR and 13C-NMR from n-hexane extract of M. vitifolia supported by LC-MS/MS data. Histamine formation in fish was determined after 30 min treatment with 4-hydroxybenzoic acid solution is around 40 – 51 mg / 100 g of fish, while treatment with M. vitifolia and Bidens pilosa extracts were less than 10 mg / 100 g of fish. This is the indication of high potential of both extract as preserver of fish products. Many of the identified substances have bioactivity like antimicrobial, anticancer, anti-inflammatory, antioxidant, and more, which influence the extracts’ ability to inhibit the formation of histamine in fish.

“…In this study, the structure of six closely related carotenoids was successfully characterized and quantified from a mixture. In another study, NMR and GC-MS techniques in combination were used to investigate the quality of lipids and corresponding FAMEs composition in Chlorella vulgaris , Spirulina platensis and Tetraselmis affchuii after treatment in different media composition, to explore their biodiesel potential [ 98 ].…”

Complementary Analytical Platforms of NMR Spectroscopy and LCMS Analysis in the Metabolite Profiling of Isochrysis galbana

This study was designed to profile the metabolites of Isochrysis galbana, an indigenous and less explored microalgae species. 1H Nuclear Magnetic Resonance (NMR) spectroscopy and Liquid Chromatography-Mass Spectrometry (LCMS) were used to establish the metabolite profiles of five different extracts of this microalga, which are hexane (Hex), ethyl acetate (EtOAc), absolute ethanol (EtOH), EtOH:water 1:1 (AqE), and 100% water (Aq). Partial least square discriminant analysis (PLS–DA) of the generated profiles revealed that EtOAc and Aq extracts contain a diverse range of metabolites as compared to the other extracts with a total of twenty-one metabolites, comprising carotenoids, polyunsaturated fatty acids, and amino acids, that were putatively identified from the NMR spectra. Meanwhile, thirty-two metabolites were successfully annotated from the LCMS/MS data, ten of which (palmitic acid, oleic acid, α-linolenic acid, arachidic acid, cholesterol, DHA, DPA, fucoxanthin, astaxanthin, and pheophytin) were similar to those present in the NMR profile. Another eleven glycerophospholipids were discovered using MS/MS-based molecular network (MN) platform. The results of this study, besides providing a better understanding of I.galbana’s chemical make-up, will be of importance in exploring this species potential as a feed ingredient in the aquaculture industry.

Biodiesel made from renewable energy sources is gaining popularity due to its environmental and economic benefits. In this work, the effect of the most important reaction variables was investigated during the acid‐catalyzed of Spirulina sp. microalgae oil to biodiesel. Results showed that the biodiesel was obtained at 60°C for 8 h using 30 g of dry Spirulina sp. powder in 300 mL of n‐hexane. Physical characteristics of the biodiesel produced from Spirulina sp. were confirmed using, evaporation temperature, flash point, freeze point, and fire point. The presence of bonds of CH3, ROH, RC≡C‐H, ‐CH = CH‐CH2)n, R‐CH2‐X, and ArOH in the biodiesel 1H NMR spectrum. Further, the biodiesel produced from the Spirulina sp. subjected to FT‐IR and GC MS which revealed the aliphatic hydrocarbons and the list of compounds such as Oleic acid, 9‐octadecenal etc.
