Adolescents' dietary polyphenol intake in relation to serum total antioxidant capacity: the HELENA study. Int J Food Sci Nutr 2022; 73:71-81. [PMID: 33858286 DOI: 10.1080/09637486.2021.1910631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Revised: 03/18/2021] [Accepted: 03/26/2021] [Indexed: 10/21/2022]
Abstract
We evaluated the association between intake of total polyphenols, polyphenol classes and the 10 most consumed individual polyphenols with serum total antioxidant capacity (TAC) in 749 European adolescents (53% girls; 15% overweight; 12.5-17.5 years-old) from the cross-sectional HELENA study of 2006-2007. Dietary polyphenol intake was calculated from two non-consecutive 24-h recalls matched with the Phenol-Explorer database. Multilevel linear models examined the associations between dietary polyphenols and TAC. Polyphenol intake was rather low (median = 321mg/day; p25 = 158; p75 = 536) and TAC was comparable to other literature findings (median = 1.57 mmol/L; p25 = 1.45; p75 = 1.74). Total polyphenol intake, polyphenol classes and the top 10 compounds were not associated with TAC in a linear, quadratic or cubic way in partially or fully confounder-adjusted models. A direct anti-oxidative effect of dietary polyphenol intake was not observed in European adolescents. Polyphenol biomarkers and additional antioxidant measures are needed in future prospective studies to confirm these results.

Rajamani K, Thirugnanasambandan SS. Polyphenols from brown alga, Padina boergesenii (Allendar & Kraft) decelerates renal cancer growth involving cell cycle arrest and induction of apoptosis in renal carcinoma cells. ENVIRONMENTAL TOXICOLOGY 2018; 33:1135-1142. [PMID: 30126067 DOI: 10.1002/tox.22619] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2018] [Revised: 06/23/2018] [Accepted: 06/24/2018] [Indexed: 06/08/2023]
Abstract
In our previous work, we assessed the ameliorative effect of crude extract from Padina boergesenii. In this report, we have extended these study by fractionating the methanol extract with methanol:ethylacetate (1:3,v/v) (MME-F) and assessed the cytotoxic effect of MME-F fraction in human renal carcinoma cell lines (A498 and ACHN). The fraction had time-and dose-dependent inhibition of cancer cell proliferation, migration with deceleration of cancer growth at EC50 -22.73 μg in A498 and 26.43 μg in ACHN cells. Cells treated at EC50 value 25 μg displayed twofold greater ability to induce early and late stage of apoptosis. The cells treated with polyphenolic fraction (MME-F) induced cell cycle arrest at G2/M phase. HPLC/DAD chromatographic procedures quantified polyphenols from active fraction (MME-F). These data revealed the functional activity of polyphenols from brown alga, P. boergesenii as a potent inhibitor of cancer proliferation with induction of apoptosis, it suggest their applicability in preventing cancer metastasis.

Chin J Integr Med 2016; 24:117-124. [PMID: 28000096 DOI: 10.1007/s11655-016-2270-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2014] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To investigate the relationship between tissue distributions of modified Wuzi Yanzong prescription (, MWP) in rats and meridian tropism theory. METHODS A high-performance liquid chromatography with Fourier transform-mass spectrometry (HPLC-FT) method was used to identify the metabolites of MWP in different tissues of rats after continued oral administration of MWP for 7 days. The relationship between MWP and meridian tropism theory was studied according to the tissue distributions of the metabolites of MWP in rats and the relevant literature. RESULTS Nineteen metabolites, mainly flavanoid compounds, were detected in the different rat tissues and classified to each herb in MWP. Further, it was able to establish that the tissue distributions of the metabolites of MWP were consistent with the descriptions of meridian tropism of MWP available in literature, this result might be useful in clarifying the mechanism of MWP on meridian tropism. In the long run, these data might provide scientific evidence of the meridian tropism theory to further promote the reasonable, effective utilization, and modernization of Chinese medicine. CONCLUSION The tissue distributions of MWP in vivo were consistent with the descriptions of meridian tropism of MWP.
