“…As examples, Liu et al and Ćirić et al have developed methods based on the coupling of a triple quadrupole (QqQ) mass spectrometer to a liquid chromatograph for quantitative analysis of five and six of the main flavonoids, respectively, in orange peel [21,22]. A more ambitious research was developed by Delpino-Rius et al, who proposed a method for quantitation of fourteen flavonoids in processed fibers from the citrus juice industry by LC-DAD/Fluorescence detection with confirmatory analysis by LC-QqQ MS/MS [23]. Similarly, LC-DAD-QqQ MS/MS coupling was critical in the study carried out by Abad-García et al, who identified and relatively quantified 58 phenolic compounds in juices from orange, tangerine, lemon and grapefruit, including 54 flavonoids [24].…”

“…84 In a previous study, the TPC recovery during spray drying of one 85 type of citrus peel extract (orange peel extract) has been reported 86 [11]. Several authors have also previously reported the antioxidant 87 contents of different types of citrus peel extracts [3,5,[12][13][14] in a refrigerator at 4°C until extraction that the same day. 113 The extraction was carried out in a Soxhlet extraction unit using The operating conditions were shown in Table 1, which were 135 determined to provide a peak yield, as reported in a previous study 136 [11].…”

“…The flow rate was 0.500 ml/min. A linear gradient elution was performed by varying the proportion of solvent A to solvent B, according to Delpino-Rius et al [26]. The data were acquired using the chromatographic behavior and UV-vis absorption spectra, together with published data on the main phenolic compounds in the samples.…”

Objective:The main objective of this study is to evaluate the chemical and bioactive properties of Eugenia stipitata (Myrtaceae) fruit seeds collected in the Andean region of Colombia using an ethanolic extract, a dichloromethane fraction (DF), and a hydroalcoholic residue.Methods: E. stipitata seeds were evaluated using bromatological analysis; these were macerated (ethanol 96%) and partitioned (dichloromethane). Phytophenols composition of the samples was tested by high-pressure liquid chromatography-mass spectrometry and Folin-Ciocalteu method, then calculated as gallic acid equivalents (GAEs). Antiradical capacity was tested by 2,2-diphenyl-1-picrylhydrazyl (DPPH • ) and 3-ethylbenzthiazoline-6sulfonic acid (ABTS •+ ) and inhibitory concentration 50% (IC 50 ) was calculated; antioxidant capacity was determined using ferric reducing antioxidant power, oxygen radical absorbance capacity, and OH • radical and hemolysis inhibition assays. Anthelmintic activity against Panagrellus redivivus and ovine gastrointestinal (GI) nematodes and toxicity on human blood cells were tested.Results: E. stipitata seeds contain protein, sulfur, boron, iron, and copper. The ethanolic extract exhibited significant anthelmintic activity against freeliving and GI nematodes, which would be associated with the phytophenols content, mostly tannins (29.14 g GAE/100 g). DF displayed the highest antiradical capacity in DPPH • and ABTS •+ (IC 50: 2.65 and 0.33 mg/l, respectively) methods, antioxidant capacity, and hemolysis inhibition of human erythrocytes (IC 50: 200 mg/l). There were no toxic metabolites to human blood cells. Conclusion:These findings would be useful for promoting the use of E. stipitata seeds, collected in the Colombian Andean region, in biotechnological processes. This is the earliest paper showing a study carried out in Colombia with an interest in evaluating chemical and biological characteristics of E. stipitata seeds.
