Turmeric powder (Curcuma longa L.) that contained 2·55 % TCMN was used as a source of TCMN. Six cage replicates of five chicks each were assigned to each of six dietary treatments, which included: basal diet; basal diet supplemented with 444 mg/kg TCMN; basal diet supplemented with 1·0 mg/kg AFB1; basal diet supplemented with 74 mg/kg TCMN and 1·0 mg/kg AFB1; basal diet supplemented with 222 mg/kg TCMN and 1·0 mg/kg AFB1; basal diet supplemented with 444 mg/kg TCMN and 1·0 mg/kg AFB1. The addition of 74 and 222 mg/kg TCMN to the AFB1 diet significantly (P,0·05) improved weight gain and feed efficiency. Increase (P,0·05) in relative liver weight in birds fed AFB1 was significantly reduced (P,0·05) with the addition of 74, 222 and , subject to the Cambridge Core terms of use, available at 444 mg/kg TCMN to the AFB1 diet. The inclusion of 222 mg/kg TCMN ameliorated the adverse effects of AFB1 on serum chemistry in terms of total protein, albumin and g-glutamyl transferase activity. The decreased antioxidant functions due to AFB1 were also alleviated by the inclusion of 222 mg/kg TCMN. It is concluded that the addition of 222 mg/kg TCMN to the 1·0 mg/kg AFB1 diet demonstrated maximum antioxidant activity against AFB1.

Gabriela Mazzanti * and Silvia Di Giacomo Department of Physiology and Pharmacology, Sapienza - University of Rome, P.le Aldo Moro 5, 00185 Rome, Italy. * Correspondence: gabriela.mazzanti@uniroma1.it; Tel.: +39-064-991-2903 Academic Editor: Luigia Trabace Received: 26 July 2016; Accepted: 12 September 2016; Published: 17 September 2016 Abstract: A growing body of in vitro and in vivo evidences shows a possible role of polyphenols in counteracting neurodegeneration: curcumin and resveratrol are attractive substances in this regard. In fact, epidemiological studies highlight a neuroprotective effect of turmeric (rhizome of Curcuma longa L.), the main source of curcumin. Moreover, the consumption of red wine, the main source of resveratrol, has been related to a lower risk of developing dementia. In this review, we analyzed the published clinical trials investigating curcumin and resveratrol in the prevention or treatment of cognitive disorders. The ongoing studies were also described, in order to give an overview of the current search on this topic. The results of published trials (five for curcumin, six for resveratrol) are disappointing and do not allow to draw conclusions about the therapeutic or neuroprotective potential of curcumin and resveratrol. These compounds, being capable of interfering with several processes implicated in the early stages of dementia, could be useful in preventing or in slowing down the pathology. To this aim, an early diagnosis using peripheral biomarkers becomes necessary. Furthermore, the potential preventive activity of curcumin and resveratrol should be evaluated in long-term exposure clinical trials, using preparations with high bioavailability and that are well standardized.

Cancer onset and progression have been linked to oxidative stress by increasing DNA mutations or inducing DNA damage, genome instability, and cell proliferation and therefore antioxidant agents could interfere with carcinogenesis. It is well known that conventional radio-/chemotherapies influence tumour outcome through ROS modulation. Since these antitumour treatments have important side effects, the challenge is to develop new anticancer therapeutic strategies more effective and less toxic for patients. To this purpose, many natural polyphenols have emerged as very promising anticancer bioactive compounds. Beside their well-known antioxidant activities, several polyphenols target epigenetic processes involved in cancer development through the modulation of oxidative stress. An alternative strategy to the cytotoxic treatment is an approach leading to cytostasis through the induction of therapy-induced senescence. Many anticancer polyphenols cause cellular growth arrest through the induction of a ROS-dependent premature senescence and are considered promising antitumour therapeutic tools.

Despite the initial challenges associated with the robust and irregular structure of lignin, the valorization of this intriguing aromatic biopolymer has come a long way: recently, many creative strategies emerged that deliver defined products via catalytic or biocatalytic depolymerization in good yields. The purpose of this review is to provide insight into these novel approaches and the potential application of such emerging new structures for the synthesis of biobased polymers or pharmacologically active molecules. Existing strategies for functionalization or defunctionalization of lignin- based compounds are also summarized. Following the whole value chain from raw lignocellulose through depolymerization to application whenever possible, specific lignin-based compounds emerge that could be in the future considered as potential lignin- derived platform chemicals.

Additionally, large depositions of amyloid ␤-peptide (A␤) are observed, and many researchers opine that A␤ is central to the pathogenesis of AD. Our laboratory combined these two observations in a comprehensive model for neurodegeneration in AD brains centered around A␤-induced oxidative stress. Given the oxidative stress in AD and its potentially important role in neurodegeneration, considerable research has been conducted on the use of antioxidants to slow or reverse the pathology and course of AD. One source of antioxidants is the diet. This review examines the literature of the effects of endogenous and exogenous, nutritionally-derived antioxidants in relation to AD. In particular, studies of glutathione and other SH-containing antioxidants, vitamins, and polyphenolic compounds and their use in AD and modulation of A␤-induced oxidative stress and neurotoxicity are reviewed. © 2002 Elsevier Science Inc.

Moreover, evaluate the effect of the bleached turmeric extract on dentin microhardness compared to sodium hypochlorite as an endodontic irrigant. Methods: Quantification of curcuminoids was done by HPLC/MS test, evaluation of total phenols percentage was done using Folin-Ciocalteu reagent while antioxidant properties were evaluated using DPPH free scavenging ability. For the evaluation of microhardness, a total of 14 teeth were used. Mechanical preparation with intervening irrigation according to the corresponding group was done. Each tooth was then sectioned vertically into two halves and equally divided into two groups to be immersed in the corresponding irrigant solution. VHN was recorded before and after immersion. Statistical analysis of data obtained from each test was performed on basis of p-value<0.05 for significance. Results: Quantification by HPLC/MS test showed that the amount of the curcuminoid was lower in the bleached turmeric extract than the unbleached turmeric extract. Also, total phenols percent in the bleached turmeric extract was the least among the test samples while the antioxidant properties of the bleached turmeric extract was the highest among the tested samples.

Curcuminoids, as the principle active compounds of turmeric, consist of curcumin (about 77%), demethoxycurcumin (about 17%), and bisdemethoxycurcumin (about 3%). Studies showed that curcuminoids, especially curcumin, possesses antioxidant, free radical scavenging activities, and thus have a health-promoting effect in human and animals. Of the three curcuminoids, extensive research on the biological activity of curcumin was carried out for decades. However, its natural analogues bisdemethoxycurcumin was relatively less investigated. Based the records, there was still controversy regarding the relative potency of antioxidant activity of curcuminoid that is dependent on different cell types and animal models, which ultimately affected their beneficial effects on the intestinal health and animal production as well. Thus, whether curcumin and bisdemethoxycurcumin shared the same efficiency of antioxidant activity in chicken erythrocytes and broiler chickens remains unknown.

Six cage replicates of five chicks each were assigned to each of six dietary treatments, which included: basal diet; basal diet supplemented with 444 mg/kg TCMN; basal diet supplemented with 1·0 mg/kg AFB1; basal diet supplemented with 74 mg/kg TCMN and 1·0 mg/kg AFB1; basal diet supplemented with 222 mg/kg TCMN and 1·0 mg/kg AFB1; basal diet supplemented with 444 mg/kg TCMN and 1·0 mg/kg AFB1. The addition of 74 and 222 mg/kg TCMN to the AFB1 diet significantly (P,0·05) improved weight gain and feed efficiency.

COMPARISON OF BIOACTIVITIES AND COMPOSITION OF CURCUMIN- FREE TURMERIC (CURCUMA LONGA L.) OILS FROM DIFFERENT SOURCES A Thesis Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Master of Science Food, Nutrition and Culinary Science by Yongxiang Yu December 2006 Accepted by: Dr. Feng Chen, Committee Chair Dr. Xi Wang Dr. Felix H Barron Dr. Jeff Adelberg ABSTRACT Composition, antioxidant capacities and cell inhibition properties of curcumin- free turmeric (Curcuma longa L.) oils from different sources were evaluated by chromatographic method, two different in vitro antioxidative activity assays (DPPH* free radical scavenging assay and reducing power assay) and two different cancer cell lines (Caco-2 and MCF-7). Turmeric oil A (TOA) contains zingiberene, turmerone, and ar- turmerone, while turmeric oil B (TOB) contains 1-phellandrene and α-terpinolene as the major compounds.
