Kaur K, Schmitt-Kopplin P, Malik AK. Green and efficient extraction of phenolic compounds from Neem leaves using deep eutectic solvents based ultrasonic-assisted extraction. Food Chem 2024; 451:139500. [PMID: 38696941 DOI: 10.1016/j.foodchem.2024.139500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 04/15/2024] [Accepted: 04/24/2024] [Indexed: 05/04/2024]
Abstract
Deep eutectic solvent (DES) combined with ultrasonic-assisted extraction was employed as an environmentally friendly technique for extracting antioxidant phenolic compounds from Neem leaves in place of organic solvents. Choline chloride-Ethylene glycol (1:2) with 40% V/V water content (DES-1) was investigated as a potential total phenolic content extractant (38.2 ± 1.2 mg GAE/g DW, where GAE: gallic acid equivalent, DW: dry weight). The optimal operational parameters assessed using single-factor experiments to maximize the total phenolic compounds content were as follows: extraction time of 30 min, 40% V/V water content, liquid-solid ratio of 15:1, and room temperature. Additionally, the in-vitro antioxidant experiments (2,2-diphenyl-1- picrylhydrazyl radical scavenging assay and ferric reducing antioxidant power assay) demonstrated the DES-1-based extract of Neem leaves as a potent antioxidant agent, compared to traditional solvents. Moreover, microscopic morphological analysis supported the effectiveness of DES-1 for the noticeable alteration in the fiber surface structure of Neem leaves after extraction which benefited in the release of polyphenols from these leaves. Eventually, the mass analysis of the extract disclosed the presence of eleven polyphenols in the extract. The Green Analytical Procedure Index revealed the greenness of the extraction method.

Abstract
Curcumin is the major bioactive component in turmeric with potent antioxidant activity. Little is known about how pulsed light (PL) technology (an emerging non-thermal food processing technology relying on high intensity short duration flashes of light) can affect the chemical stability and antioxidant capacity of curcumin. This study found that PL treatment of fluence levels from 0 to 12.75 J/cm2 produced a fluence-dependent reduction in curcumin content. These results paralleled the production of a tentative curcumin dimer, identified as a potential photochemical transformation product. PL-treated curcumin at relatively higher fluence levels decreased chemical-based ORAC and ABTS antioxidant capacity, relative to control (P < 0.05). This contrasted the effect observed to increase coincidently both intracellular antioxidant capacity (e.g., DCFH-DA (P < 0.05)) and GSH/GSSG ratio (P < 0.05), respectively, in cultured differentiated Caco-2 cells. In conclusion, the application of PL on curcumin results in photochemical transformation reactions, such as dimerization, which in turn, can enhance biological antioxidant capacity in differentiated Caco-2 cells.

Integrative omics analyses of the ligninolytic Rhodosporidium fluviale LM-2 disclose catabolic pathways for biobased chemical production. BIOTECHNOLOGY FOR BIOFUELS AND BIOPRODUCTS 2023; 16:5. [PMID: 36624471 PMCID: PMC9830802 DOI: 10.1186/s13068-022-02251-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Accepted: 12/18/2022] [Indexed: 01/11/2023]
Abstract
BACKGROUND Lignin is an attractive alternative for producing biobased chemicals. It is the second major component of the plant cell wall and is an abundant natural source of aromatic compounds. Lignin degradation using microbial oxidative enzymes that depolymerize lignin and catabolize aromatic compounds into central metabolic intermediates is a promising strategy for lignin valorization. However, the intrinsic heterogeneity and recalcitrance of lignin severely hinder its biocatalytic conversion. In this context, examining microbial degradation systems can provide a fundamental understanding of the pathways and enzymes that are useful for lignin conversion into biotechnologically relevant compounds. RESULTS Lignin-degrading catabolism of a novel Rhodosporidium fluviale strain LM-2 was characterized using multi-omic strategies. This strain was previously isolated from a ligninolytic microbial consortium and presents a set of enzymes related to lignin depolymerization and aromatic compound catabolism. Furthermore, two catabolic routes for producing 4-vinyl guaiacol and vanillin were identified in R. fluviale LM-2. CONCLUSIONS The multi-omic analysis of R. fluviale LM-2, the first for this species, elucidated a repertoire of genes, transcripts, and secreted proteins involved in lignin degradation. This study expands the understanding of ligninolytic metabolism in a non-conventional yeast, which has the potential for future genetic manipulation. Moreover, this work unveiled critical pathways and enzymes that can be exported to other systems, including model organisms, for lignin valorization.

Identification of Oxindoleacetic Acid Conjugates in Quinoa (Chenopodium quinoa Willd.) Seeds by High-Resolution UHPLC-MS/MS. Molecules 2022; 27:molecules27175629. [PMID: 36080392 PMCID: PMC9458244 DOI: 10.3390/molecules27175629] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 08/23/2022] [Accepted: 08/26/2022] [Indexed: 11/17/2022] Open
Abstract
Quinoa (Chenopodium quinoa Willd.) has a high nutritional value and it contains a high number and high amounts of specialized metabolites. These metabolites include, for example, phenolic acids, flavonoids, terpenoids and steroids. In addition, it is known to contain N-containing metabolites, such as betalains. Here, we report the presence and identification of 14 new oxindoleacetate conjugates in quinoa by high-resolution ultrahigh-performance liquid chromatography quadrupole-time-of-flight tandem mass spectrometry (UHPLC-QTOF-MS/MS) and ultrahigh-resolution UHPLC-QOrbitrap-MS/MS. The oxindoleacetate conjugates were extracted from dried and ground quinoa seeds using either methanol/water or acetone/water (4:1, v/v) and were further concentrated into aqueous phase and analyzed by UHPLC with reverse-phase chromatography using acetonitrile and 0.1% aqueous formic acid as eluents. High-resolution hybrid LC-MS/MS techniques, including full scan MS with in-source collision, induced dissociation, and data dependent-MS2(TopN) with stepped normalized collision energies using N2 as collision gas and data-independent acquisition (MSE) using ramped collision energies and argon as collision gas enabled their analysis directly from the crude quinoa seed extract. The oxindoleacetate conjugates were found to be present in both conventional and organic farmed seeds. According to our best knowledge, this is the first time hydroxy-oxindoles have been reported in quinoa.

Abstract
Bagasse is a byproduct generated during the process of making the traditional Andean drink named “chicha de jora” in Peru, which is a potential source for the extraction of ferulated arabinoxylan (FAX). The aim of this study was to extract and characterize the FAX from bagasse and determine its antioxidant and antihyperglycemic capacity in vitro. As a result, FAX of molecular weight ≥3.5 kDa presented moisture content, pH, total ash, proteins, and total phenolic content with values of 8.00%, 5.81, 2.68%, 3.78%, and 5.72 mg EAG/g, respectively. Thin-layer chromatography identified the monosaccharides L-arabinose and D-xylose. HPLC-MS/MS analysis of FAX confirmed the presence of methyl-pentofuranosides or methyl-pentopyranosides. The FT-IR spectrum presented characteristic bands of FAX. The FAX showed antioxidant capacity determined by the DPPH assay (IC50 = 6.59 mg/mL and TEAC = 7.7844 μmol/g sample), ABTS (IC50 = 6.50 mg/mL and TEAC 35.34 μmol/g sample), and FRAP (14.08 μmol AA/g and 36.63 μmol FeSO4/g). On the other hand, FAX showed glucose adsorption capacity, inhibition of glucose diffusion, and inhibition of the enzyme α-amylase (IC50 = 4.73 mg/mL). The results showed that the FAX extracted from the bagasse generated during the production of the “chicha de jora” has in vitro antioxidant and antihyperglycemic capacity.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2021; 2021:2809004. [PMID: 34992663 PMCID: PMC8727101 DOI: 10.1155/2021/2809004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 11/29/2021] [Accepted: 12/09/2021] [Indexed: 11/17/2022]
Abstract
Migraine is a disease whose aetiology and mechanism are not yet clear. Chuanxiong Rhizoma (CR) is employed in traditional Chinese medicine (TCM) to treat various disorders. CR is effective for migraine, but its active compounds, drug targets, and exact molecular mechanism remain unclear. In this study, we used the method of systems pharmacology to address the above issues. We first established the drug-compound-target-disease (D-C-T-D) network and protein-protein interaction (PPI) network related to the treatment of migraine with CR and then established gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. The results suggest that the treatment process may be related to the regulation of inflammation and neural activity. The docking results also revealed that PTGS2 and TRPV1 could directly bind to the active compounds that could regulate them. In addition, we found that CR affected 11 targets that were more highly expressed in the liver or heart but were the lowest in the whole brain. It also expounds the description of CR channel tropism in TCM theory from these angles. These findings not only indicate that CR can be developed as a potential effective drug for the treatment of migraine but also demonstrate the application of systems pharmacology in the discovery of herbal-based disease therapies.

Abstract
ETHNOPHARMACOLOGY RELEVANCE The combination of Chuanxiong Rhizoma (Ligusticum chuanxiong Hort., umbelliferae) with Xiangfu Rhizoma (the rhizoma of Cyperus rotundus L., Cyperaceae), is deemed as CR-XR herb-pair (Yaodui) in China. Their compatible mechanism needs a further research using modern analytical techniques and bioinformatic tool. METHODS Head Space- Solid Phase Micro Extraction coupled with Gas Chromatography/Mass Spectrometer detection (HS-SPME-GC/MS) and Liquid Chromatography coupled to quadrupole Time of Flight - Mass Spectrometry (LC-qTOF-MS) were applied in an accurate identification of the absorbed phytochemicals in mice serum; Their potential targets were available after compound-protein interaction (CPI) prediction and molecular docking verification; Then the corresponding disease types, as well as the relevant Traditional Chinese Medicine (Zhongyi) syndromes (Zheng), were matched from databases and references. RESULTS Resolution from hyphenated chromatographic datasets, thirty-eight phytochemicals were detected in serum samples from mice. Seventy potential target proteins were thereby found through a bioinformatic calculation, which mainly focused on circulatory, endocrine and nervous diseases in Western medicine, also related with Qizhi and Xueyu Zheng from the perspective of Zhongyi. Part of the relationships among compound-Target-Disease have been confirmed by literatures. These virtual data were sketched out as 'The active Compound - potential Target' network, 'Target - Disease' network and 'Target - Zhongyi Disease' network, in which the network topology was used to analyze them. CONCLUSIONS Our work successfully explained the compatible mechanism of CR-XR Yaodui, which exert 'multi-components, multi targets' in treating Qizhi and Xueyu Zheng.
