“…Compound 1 showed the characteristic fragmentation pattern of an ellagitannin with two HHDP units. The [M − H] − molecular ion at m / z 783.3 amu, and MS 2 fragment ions at m / z 480.7 and 300.6 allowed the tentative identification of this compound as a pedunculagin isomer [31]. Compound 6 showed a [M − H] − molecular ion at m / z 633.9 amu and MS 2 fragment ions at m / z 462.7 [M – H − galloyl] − and 300.8 amu [M − H − galloyl hexose] − .…”

Polyphenol Composition and (Bio)Activity of Berberis Species and Wild Strawberry from the Argentinean Patagonia

et al. 2019

View full text Add to dashboard Cite

The Argentinean Patagonia berries Berberis microphylla, Berberis darwinii, and Fragaria chiloensis ssp. chiloensis f. patagonica were investigated for their polyphenol content and composition by means of liquid chromatography coupled to diode array detection and electrospray ionization tandem mass spectrometry. The in vitro antioxidant activity and inhibition of metabolic syndrome-associated enzymes (α-glucosidase, α-amylase, and lipase) of the fruit extracts was assessed. The most complex polyphenol profile was found in the Berberis samples, with 10 anthocyanins, 27 hydroxycinnamic acids, 3 proanthocyanidins, 2 flavan-3-ol, and 22 flavonols. Fragaria presented four anthocyanins, nine ellagitannins, two proanthocyanidin dimers, one flavan-3-ol, and five flavonols. The Berberis samples showed the best antioxidant capacity, while Fragaria displayed better activity against α-glucosidase and lipase. The phenolic content and composition of the Argentinean Patagonia berries was similar to that reported for Chilean samples but with some chemical differences between Eastern (Argentina) and Western (Chile) Patagonia. The data obtained supports the consumption of these berries as sources of beneficial polyphenols.

“…Despite the differences and advantages reported for tandem mass spectrometers, multiple types of mass spectrometers can be used for polyphenol analysis, such as quadrupole (single or triple) [49,50], ion trap mass spectrometer [80][81][82], time-of flight or quadrupole-time-of-flight [10,79,80,83], and Orbitrap [33] among others. In the consulted literature there are studies demonstrating efficacy in polyphenols detection and quantification with different mass analyzers (Table 3).…”

“…In this regard, Nijat et al [ 33 ] combined the ultra-high performance liquid chromatography coupled to quadrupole-orbitrap high resolution mass spectrometry (UHPLC–Q–orbitrap–HRMS) and high performance liquid chromatography triple-quadrupole linear ion trap mass spectrometry (HPLC–QqQ–LITMS) to detect and quantify polyphenols in Meiguihua oral solution; Jin et al [ 83 ] studied the identification of polyphenols in mulberry cultivars with both TOF/MS and QqQ–MS, while Quatrin et al [ 80 ] reported the characterization and identification of tannins, flavonols, anthocyanins, and matrix-bound polyphenols from jaboticaba fruit peel with two different mass spectrometer analyzers (LC–TRAP–MS/MS and LC–Q–TOF–MS/MS), while the quantification was carried out using HPLC–DAD technique. For quantitative analysis, the use of triple quadrupole mass spectrometers (QqQ) is common, which are capable of performing multiple reaction monitoring (MRM) [ 84 , 85 ].…”

Determination of Polyphenols Using Liquid Chromatography–Tandem Mass Spectrometry Technique (LC–MS/MS): A Review

et al. 2020

View full text Add to dashboard Cite

In recent years, the consumption of polyphenols has been increasing, largely due to its beneficial effects on health. They are present in a wide variety of foods, but their extraction and characterization are complicated since they are mostly in complex matrices. For this reason, the use of selective, sensitive, and versatile analytical techniques such as liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) is necessary. In this review, the most relevant studies of the last years regarding the analysis of polyphenols in different matrices by comprehensive LC–MS/MS are discussed. Relevant steps such as extraction, sample purification, and chromatographic analysis methods are emphasized. In particular, the following methodological aspects are discussed: (a) the proper selection of the extraction technique, (b) the extraction and elution solvents, (c) the purification step, (d) the selection of both stationary and mobile phases for the chromatographic separation of compounds, and (e) the different conditions for mass spectrometry. Overall, this review presents the data from the most recent studies, in a comprehensive way, thus providing and simplifying the information of the great variety of works that exist in the literature on this wide topic.

“…The extraction procedure is the most important step for recovering phenolic compounds from vegetables, directly affecting the yield of the bioactive compounds [ 11 , 12 ]. According to Wijngaard et al [ 13 ], different techniques are used to extract these compounds, as determined by conventional and non-conventional methods.…”

Obtaining Bioactive Compounds from the Coffee Husk (Coffea arabica L.) Using Different Extraction Methods

et al. 2020

View full text Add to dashboard Cite

Coffee husks (Coffea arabica L.) are characterized by exhibiting secondary metabolites such as phenolic compounds, which can be used as raw material for obtaining bioactive compounds of interest in food. The objective of this study is to evaluate different methods for obtaining the raw material and extracting solutions of bioactive compounds from coffee husks. Water bath and ultrasound-assisted extraction methods were used, using water (100%) or ethanol (100%) or a mixture of both (1:1) as extracting solutions and the form of the raw material was in natura and dehydrated. The extracts were evaluated by their antioxidant potential using DPPH radicals, ABTS, and iron reduction (ferric reducing antioxidant power (FRAP)), and later total phenolic compounds, total flavonoids, and condensed tannins were quantified the phenolic majority compounds were identified. It was verified that the mixture of water and ethanol (1:1) showed better extraction capacity of the compounds with antioxidant activity and that both conventional (water bath) or unconventional (ultrasound) methods showed satisfactory results. Finally, a satisfactory amount of bioactive compounds was observed in evaluating the chemical composition (total phenolic compounds, total flavonoids, condensed tannins, as well as the analysis of the phenolic profile) of these extracts. Corroborating with the results of the antioxidant activities, the best extracting solution was generally the water and ethanol mixture (1:1) using a dehydrated husk and water bath as the best method, presenting higher levels of the bioactive compounds in question, with an emphasis on chlorogenic acid. Thus, it can be concluded that the use of coffee husk as raw material to obtain extracts of bioactive compounds is promising. Last, the conventional method (water bath) and the water and ethanol mixture (1:1) stood out among the methods and extracting solutions used for the dehydrated coffee husk.
