Rapid extraction method followed by a d-SPE clean-up step for determination of phenolic composition and antioxidant and antiproliferative activities from berry fruits

Publication date: Available online 19 October 2019Source: Food ChemistryAuthor(s): Carina Alexandra Rodrigues, Antonio Eduardo Nicácio, Joana Schuelter Boeing, Franciele Pelegrin Garcia, Celso Vataru Nakamura, Jesuí Vergílio Visentainer, Liane MaldanerAbstractDespite the numerous studies that have shown a wide range of biological activities to berry fruits, scientific data focusing on modern, rapid and simple extraction methods followed by a clean-up step is still lacking. Therefore, the present work was aimed at investigating the use of a fast one-step liquid–solid extraction procedure followed by a dispersive solid-phase extraction (d-SPE) clean-up step to evaluate the phenolic composition, antioxidant and antiproliferative activities from three of the principal berries found in Brazil, pomegranate (Punica granatum L.), blackberry (Rubus ulmifolius Schott.), and strawberry (Fragaria x ananassa Duch.). Under the optimized extraction conditions, sixteen phenolic compounds were determined by UHPLC-MS/MS analysis and all berry extracts showed antioxidant activity and antiproliferative effects on cervical (HeLa) and colon (HT-29) cancer cells. Overall, these results highlight the importance of the clean-up step for more reliable data in studies of health-promoting proprieties from berry fruits.

Conclusion: Since stage-specific survival is similar in Kuwait and the US, late stage at diagnosis is likely to be a major contributing factor to the overall lower survival in Kuwait than in the US. Increasing public awareness of cancer risk factors and symptoms and investment in early detection will be vital to reduce the proportion of patients diagnosed at a late stage and to improve survival.

rik The present study aimed to identify the chemical constituents and to assess the in-vitro, antimicrobial, anticancer, antioxidant, metabolic enzymes and cyclooxygenase (COX) inhibitory properties of essential oil (EO) of Stachys viticina Boiss. leaves. The S. viticina EO was isolated and identified using microwave-ultrasonic and GC-MS techniques, respectively. Fifty-two compounds were identified, of which endo-borneol was the major component, followed by eucalyptol and epizonarene. The EO was evaluated against a panel of in-vitro bioassays. The EO displayed antimicrobial activity against methicillin-resistant Staphy...

Creatine, the organic acid that is popularly taken as a supplement by athletes and bodybuilders, serves as a molecular battery for immune cells by storing and distributing energy to power their fight against cancer, according to new UCLA research.The study, conducted in mice and published in the Journal of Experimental Medicine, is the first to show that creatine uptake is critical to the anti-tumor activities of CD8 T cells, also known as killer T cells, the foot soldiers of the immune system. The researchers also found that creatine supplementation can improve the efficacy of existing immunotherapies.“Because oral ...

This study aimed to study the travel distance to cancer patient's GP and to the hospital of diagnosis and the association with tumour stage for 12 cancer types. A cohort study was conducted including cancer patients in Denmark diagnosed between 2005 and 2016 with rectum, malignant melanoma, breast, testis, oesophageal, colon, cervix, prostate, stomach, pancreatic, lung and ovary cancer (n = 256,663). Distance to each patient's GP and to the hospital of diagnosis were calculated using ArcGIS, Network Analyst. The results showed that for most easy-to-diagnose cancer types (rectum cancer, malignant melanoma, testis cancer...

Conclusions: Our data support that COX-2 is involved in the early stages of colorectal cancer development, initially affecting the tumor’s stromal microenvironment, and, subsequently, the epithelial cells. They also highlight an inverse correlation between COX-2 expression and telomerase activity in CRC, as well as differentially methylated patterns within the promoter regions of COX-2 and TERT.
