Phenolic Compounds Characterization of Caryocar brasiliense Peel with Potential Antioxidant Activity. PLANTS (BASEL, SWITZERLAND) 2024; 13:2016. [PMID: 39124134 PMCID: PMC11314331 DOI: 10.3390/plants13152016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/10/2024] [Revised: 07/13/2024] [Accepted: 07/15/2024] [Indexed: 08/12/2024]
Abstract
The pequi (Caryocar brasiliense) fruit peel, despite being frequently discarded, has a high content of bioactive compounds, and therefore has a high nutritional value. The present study aimed to explore the bioactivities in the pequi peel, particularly their potential health benefits at the level of antioxidant activity. The exploitation of this fruit could also present significant economic benefits and applications of pequi by-products would represent a reduction in waste, having a positive impact on the environment. Phenolic compounds present in the pequi exocarp and external mesocarp were identified by paper spray mass spectrometry (PS-MS) and quantified by HPLC. The total phenolic content (TPC) along with the amount of 2,2-diphenyl-1-picrylhydrazyl (DPPH), Ferric Reducing Antioxidant Power (FRAP), and the amount of 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) were also determined in peel extracts. Epicatechin was the most abundant phenolic compound found, followed by the caffeic, salicylic, and gallic acids. In addition, fingerprinting revealed compounds related to several beneficial health effects. In short, the results obtained were encouraging for potential applications of pequi peel in the field of functional foods.

[PMID: 38046170 PMCID: PMC10686867 DOI: 10.1016/j.heliyon.2023.e22060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 11/01/2023] [Accepted: 11/03/2023] [Indexed: 12/05/2023] Open
Abstract
The Amazon rainforest encompasses one of the largest biodiversities of the world and is home to a wide variety of food and therapeutic plants. Due to the diversity of components, the fruits of the Amazon biome possess essential physicochemical, nutritional, and pharmacological properties, strengthening the idea that fruit consumption may provide benefits to human health. Thus, the objective of this study was to investigate the current scenario of the use of Amazonian fruits on the development of food, pharmaceutical, nutraceutical, or cosmetic products through the study of filed patents. A prospecting strategy conducted focusing on patents was used to investigate the application of the following fruits: Euterpe oleracea, Oenocarpus bacaba, Caryocar brasiliense, Garcinia gardneriana, Nephelium lappaceum, and Astrocaryum vulgare. A total of 264 patent documents were found. In 2016, a peak of 33 applications was reached, followed by a peak in 2019 with 32 applications. The study is distributed in three main application areas: cosmetics, pharmaceuticals, and food. The Asian continent was the region with the world leadership in this theme, followed by Brazil. Thus, technological prospection studies can foster investments in translational research to elucidate the effects and properties of Amazonian fruits, which can generate sustainable development of new products with industrial potential.

Protective Effect of Alpinia oxyphylla Fruit against tert-Butyl Hydroperoxide-Induced Toxicity in HepG2 Cells via Nrf2 Activation and Free Radical Scavenging and Its Active Molecules. Antioxidants (Basel) 2022; 11:1032. [PMID: 35624896 PMCID: PMC9137508 DOI: 10.3390/antiox11051032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 05/19/2022] [Accepted: 05/20/2022] [Indexed: 11/16/2022] Open
Abstract
Alpinia oxyphylla Miq. (Zingiberaceae) extract exerts protective activity against tert-butyl hydroperoxide-induced toxicity in HepG2 cells, and the antioxidant response element (ARE) luciferase activity increased 6-fold at 30 μg/mL in HepG2 cells transiently transfected with ARE-luciferase. To identify active molecules, activity-guided isolation of the crude extract led to four sesquiterpenes (1, 2, 5, 6) and two diarylheptanoids (3 and 4) from an n-hexane extract and six sesquiterpenes (7-12) from an ethyl acetate extract. Chemical structures were elucidated by one-dimensional, two-dimensional nuclear magnetic resonance (1D-, 2D-NMR), and mass (MS) spectral data. Among the isolated compounds, eudesma-3,11-dien-2-one (2) promoted the nuclear accumulation of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) and increased the promoter property of the ARE. Diarylheptanoids, yakuchinone A (3), and 5'-hydroxyl-yakuchinone A (4) showed radical scavenging activity in 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assays. Furthermore, optimization of extraction solvents (ratios of water and ethanol) was performed by comparison of contents of active compounds, ARE-inducing activity, radical scavenging activity, and HepG2 cell protective activity. As a result, 75% ethanol was the best solvent for the extraction of A. oxyphylla fruit. This study demonstrated that A. oxyphylla exerted antioxidant effects via the Nrf2/HO-1 (heme oxygenase-1) pathway and radical scavenging along with active markers eudesma-3,11-dien-2-one (2) and yakuchinone A (3).

Abstract
Abstract Curcuma longa L., also known as turmeric, has been widely studied for its various therapeutic properties, including antineoplastic action. The ethanolic extract of the plant contains several phenolic compounds, especially curcumin. Osteosarcoma is a predominant bone tumor in dogs and humans, characterized by high metastatic potential and an unfavorable prognosis. The aim of this study was to investigate the effects of turmeric ethanol extract on canine osteosarcoma cells from established culture. The cells were cultured and treated with different curcumin concentrations (0, 10 μM, 20 μM, 50 μM, 100 μM, and 1000 μM) and exposure times (24h, 48h, and 72h). We first performed tetrazolium reduction technique (MTT) assay and calculated IC50. An immunocytochemistry assay was performed after extract treatment to verify the expression of mutated p53 and therefore study the proliferative potential of malignant cells; Bcl-2 and Ki-67 were used to assess apoptosis and the degree of malignancy, respectively. The extract enhanced the proliferation of canine osteosarcoma cells, reaching 3,819.74% at 50 μM of curcumin. The extract also significantly altered the expression of mutated p53 and Ki-67 proteins but not that of Bcl-2, suggesting that it did not induce this antiapoptotic pathway. Overall, these results are prerequisite to better understanding how natural compounds such as turmeric ethanolic extract affect cell proliferation and could be used to treat various diseases.

Abstract
Resumo A Curcuma longa L., planta conhecida popularmente como açafrão, tem sido amplamente estudada por suas diversas propriedades terapêuticas, incluindo a ação antineoplásica. O extrato etanólico da planta contém diversos compostos fenólicos, com destaque para a curcumina. O osteossarcoma é um tumor ósseo predominante em cães e humanos, caracterizado por apresentar alto potencial metastático e prognóstico desfavorável. Procurou-se investigar os efeitos de diferentes concentrações de curcumina do extrato etanólico de açafrão sobre células de osteossarcoma canino de cultura estabelecida. As células foram cultivadas e submetidas ao tratamento com extrato com diferentes concentrações de curcumina (0, 10 μM, 20 μM, 50 μM, 100 μM e 1000 μM) e tempos de exposição (24h, 48h e 72h) pelo EEA. Inicialmente, foram realizados: técnica de redução do tetrazólio (MTT) e cálculo da IC50. Posteriormente, após o tratamento com o extrato, realizou-se o ensaio de imunocitoquímica para verificar a expressão de p53 mutada e estudar o potencial proliferativo das células malignas; Bcl-2, com intuito de averiguar o estímulo de via antiapoptótica; e o marcador Ki-67, que sinaliza aumento no grau de malignidade. O extrato promoveu proliferação de células de osteossarcoma canino, com incremento de até 3819,74% na concentração de 50μM de curcumina. O composto também alterou a expressão das proteínas p53 mutante e Ki-67 significativamente, mas não alterou a expressão de Bcl-2, mostrando que não induziu a via antiapoptótica mediada por esta. Estes resultados demonstram que o extrato etanólico do açafrão apresenta potencial proliferativo sobre células de osteossarcoma canino, sugerindo a necessidade de conscientização e conhecimento dos reais efeitos de determinados compostos naturais, considerados seguros ao serem utilizados como tratamento de diversas enfermidades.
