Abstract
Alcoholic liver disease (ALD) is a serious and challenging health issue. In the past decade, natural components possessing hepatoprotective properties have gained more attention for ALD intervention. In this study, the phytochemical components of anthocyanins from purple potato were assessed using UPLC-MS/MS, and the hepatoprotective effects of purple potato anthocyanins (PPAs) were investigated in the ALD mouse model. Serum and liver biochemical parameters were determined, along with histopathological changes in liver tissue. In addition, the major contributors to alcohol-induced oxidative stress were assessed. The results indicated that the levels of aspartate transaminase and alanine transaminase were lower in the serum of the PPA-treated group than the alcohol-treated group. PPAs significantly inhibited the reduction of total cholesterol and triglycerides. Higher levels of superoxide dismutase and reduced glutathione enzymes as well as a reduction in the formation of malondialdehyde occurred in mice fed with PPAs. In addition, PPAs protected against increased alcohol-induced levels and activity of cytochrome P450 2E1 (CYP2E1), which demonstrates the effects of PPAs against alcohol-induced oxidative stress and liver injury. This study suggests that PPAs could be an effective therapeutic agent in alcohol-induced liver injuries by inhibiting CYP2E1 expression and thereby strengthening antioxidant defenses.

Abstract
The aim of this study was to investigate the anti-obesity effects of germinated waxy black rice (GWBR) extract in 3T3-L1 adipocytes. The inhibitory effect of GWBR extract against adipocyte differentiation was evaluated using Oil Red O staining and glycerol-3-phosphate dehydrogenase (GPDH) assay. GWBR extract inhibited adipocyte differentiation, but was not found to elicit any cytotoxicity. The mRNA levels of adipogenic transcriptional factors such as C/EBP-α and -β, PPAR-γ, and SREBP-1c, as well as adipogenic enzymes, including aP2, LPL, and FAS were significantly downregulated by treatment with GWBR extract compared to untreated control cells. However, mRNA levels of lipolytic genes such as HSL and ATGL, β-oxidation related genes CPT1, and UCP2 involved in thermogenesis were significantly up-regulated by treatment with GWBR extract. These data suggest that GWBR extract may be a potential functional food, and may have pharmacological applications in both the prevention and treatment of obesity.

Abstract
Liver fibrosis is a wound-healing process in response to repeated and chronic injury to hepatocytes and/or cholangiocytes. Ongoing hepatocyte apoptosis or necrosis lead to increase in ROS production and decrease in antioxidant activity, which recruits inflammatory cells from the blood and activate hepatic stellate cells (HSCs) changing to myofibroblasts. Injury to cholangiocytes also recruits inflammatory cells to the liver and activates portal fibroblasts in the portal area, which release molecules to activate and amplify cholangiocytes. No matter what origin of myofibroblasts, either HSCs or portal fibroblasts, they share similar characteristics, including being positive for α-smooth muscle actin and producing extracellular matrix. Based on the extensive pathogenesis knowledge of liver fibrosis, therapeutic strategies have been designed to target each step of this process, including hepatocyte apoptosis, cholangiocyte proliferation, inflammation, and activation of myofibroblasts to deposit extracellular matrix, yet the current therapies are still in early-phase clinical development. There is an urgent need to translate the molecular mechanism of liver fibrosis to effective and potent reagents or therapies in human.

Abstract
CONTEXT The incidence of drug-induced liver disease associated with oxidant-antioxidant imbalance is increasing. Colored rice can potentially improve these hepatic disorders through antioxidative and glutathione-restoring effects. OBJECTIVES The objective of this study is to determine the in vitro antioxidant properties of extracts from red (Hom-Dang and Hom-Kularb-Dang) and black (Hom-Dum-Sukhothai and Kum-Doi-Saket) Thai rice cultivars [Oryza sativa L. (Poaceae)] and to examine the in vivo hepatoprotective potential of Hom-Dang extract in paracetamol-treated mice. MATERIALS AND METHODS The in vitro antioxidant properties of the extracts were determined by ABTS, [Formula: see text], [Formula: see text], metal chelating capacity, and lipid peroxidation assays. To investigate hepatoprotective effects in vivo, mice administered 60 mg/kg/d paracetamol were given Hom-Dang extract (128, 256, and 512 mg/kg/d) and/or control antioxidant N-acetyl-cysteine (NAC, 150 mg/kg/d) for 7 and 30 d. Liver health was ascertained by measuring levels of hepatic transaminases (GPT/GOT), determining the glutathione profile (GSH/GSSG ratio), and histomorphological examination of liver tissue. RESULTS Hom-Dang extract showed the highest in vitro antioxidant potency (an IC50 value of 36.50 ± 0.46, 12.98 ± 0.23, 21.83 ± 2.58, 15.87 ± 0.30, and 86.21 ± 2.45 mg/mL for ABTS, OH(•), [Formula: see text], metal chelating, and lipid peroxidation, respectively). Mice administered paracetamol exhibited increases in GPT/GOT with decreases in GSH and GSH/GSSG ratio followed by histomorphological signs of liver injury. In the presence of the Hom-Dang extract, the GPT/GOT values were normalized, GSH production was induced, and the GSH/GSSG ratio was increased. CONCLUSION Thai colored rice cultivars, especially the Hom-Dang variety, are promising candidates for health supplements due to their antioxidative and hepatoprotective properties.

Abstract
This study investigated whether cyanidin-3-O-β-glucoside (Cy-3-G), a predominant anthocyanin, could exert a protective role on liver injury and its further mechanisms of the anti-fibrosis actions in mice. The results demonstrated that the treatment of Cy-3-G (800 mg/kg diet) for 8 weeks significantly attenuated hepatotoxicity and fibrosis in carbon tetrachloride (CCl4) administered mice. Cy-3-G strongly down-regulated the expression of α-smooth muscle actin (α-SMA), desmin, and matrix metalloproteinase (MMPs), which showed its suppression effect on the activation of hepatic stellate cells (HSCs). In addition, Cy-3-G favorably regulated oxidative stress and apoptosis in liver. Furthermore, Cy-3-G ameliorated the infiltration of inflammatory cells such as neutrophils and leukocytes and meanwhile suppressed the production of pro-inflammatory cytokines and growth factors. In conclusion, daily intake of Cy-3-G could prevent liver fibrosis progression in mice induced by CCl4 through inhibiting HSC activation, which provides a basis for clinical practice of liver fibrosis prevention.

Abstract
Background For a long time, honey was purportedly helpful to prevent drunkenness and relieve hangover symptoms. However, few of the assertions have experienced scientific assessment. The present study examined the effects of honey on intoxicated male mice. Methods Low or high doses of lychee flower honey (2.19 or 4.39 g/kg body weight, respectively) were single orally administrated 30 min before the ethanol intoxication of mice, followed by recording the locomotor activity by autonomic activity instrument and observing the climbing ability after alcohol. On the other hand, 2.19 g/kg honey was single orally administrated 5 min after the ethanol intoxication of mice, followed by determining the ethanol concentration in mice blood. In addition, subacute alcoholism mice models were developed and after the treatment of 2.19 g/kg honey s.i.d for successive three days, the level of serum malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) activity were detected in the models. Results Both of the two doses of honey increased the autonomic activity of alcoholized mice. Furthermore, the treatment of 2.19 g/kg honey could decrease significantly the blood ethanol concentration in intoxicated mice. The anti-intoxication activity of honey could be due to the effect of the fructose contained in the honey. Meanwhile, honey could not affect the serum MDA level and GSH-Px activity in alcoholism mice models. Conclusion Honey indeed possesses anti-intoxication activity.

Abstract
Black rice contains many biologically active compounds. The aim of this study was to investigate the protective effects of black rice extracts (whole grain extract, WGE and rice bran extract, RBE) on tert-butyl hydroperoxide (TBHP)-induced oxidative injury in HepG2 cells. Cellular reactive oxygen species (ROS), antioxidant enzyme activities, malondialdehyde (MDA) and glutathione (GSH) concentrations were evaluated as biomarkers of cellular oxidative status. Cells pretreated with 50 and 100 μg/mL of WGE or RBE were more resistant to oxidative stress in a dose-dependent manner. The highest WGE and BRE concentrations enhanced GSH concentrations and modulated antioxidant enzyme activities (glutathione reductase, glutathione-S-transferase, catalase, and superoxide dismutase) compared to TBHP-treated cells. Cells treated with RBE showed higher protective effect compared to cells treated with WGE against oxidative insult. Black rice extracts attenuated oxidative insult by inhibiting cellular ROS and MDA increase and by modulating antioxidant enzyme activities in HepG2 cells.

Abstract
Bitter gourd (Momordica charantia L.) is a common vegetable grown widely in Asia that is used as a traditional medicine. The objective of this study was to investigate whether wild bitter gourd possessed protective effects against chronic alcohol-induced liver injury in mice. C57BL/6 mice were fed an alcohol-containing liquid diet for 4 weeks to induce alcoholic fatty liver. Meanwhile, mice were treated with ethanol extracts from four different wild bitter gourd cultivars: Hualien No. 1', Hualien No. 2', Hualien No. 3' and Hualien No. 4'. The results indicated that the daily administration of 500 mg kg body weight(-1) of a Hualien No. 3' extract (H3E) or a Hualien No. 4' extract (H4E) markedly reduced the steatotic alternation of liver histopathology. In addition, the activation of serum aminotransferases (AST and ALT) and the accumulation of hepatic TG content caused by alcohol were ameliorated. The hepatoprotective effects of H3E and H4E involved the enhancement of the antioxidant defence system (GSH, GPx, GRd, CAT and SOD), inhibition of lipid peroxidation (MDA) and reduction of pro-inflammatory cytokines (TNF-α, IL-1β and IL-6) in the liver. Moreover, H3E and H4E supplementation suppressed the alcohol-induced elevation of CYP2E1, SREBP-1, FAS and ACC protein expression. These results demonstrated that ethanol extracts of Hualien No. 3' and Hualien No. 4' have beneficial effects against alcoholic fatty liver, in which they attenuate oxidative stress and inflammatory responses.

Abstract
The antioxidant potential of jujube honey, one of the most widely consumed honeys in China, has never been determined fully. In this study, jujube honey from six geographical origins in China was analyzed for individual phenolic acid, total phenolic content, and the antioxidant effect in chronic alcohol-related hepatic disease in mice. The results showed that jujube honey from Linxian of Shanxi province contained higher phenol levels, exhibited DPPH antioxidant activity, ferric ion reducing antioxidant power (FRAP) and protective effects against DNA damage. Treatment with jujube honey (Shanxi Linxian) for 12 weeks significantly inhibited serum lipoprotein oxidation, reduced the impact of alcoholism on aspartate aminotransferase (AST) and alanine aminotransferase (ALT). It also inhibited the generation of 8-hydroxy-2-deoxyguanosine (8-OHdG), lowered the levels of malondialdehyde (MDA) and increased the activity of hepatic glutathione peroxidase (GSH-Px). The study indicates that jujube honey exerts potent antioxidant activity and significant protection in hepatic disorders associated with chronic alcoholism. The protective effect is attributed to its antioxidant mechanisms and inhibition of oxidative degradation of lipids.

Abstract
This study evaluated the protective effects of purple rice (Oryza sativa L.) extract (PRE) and its major constituent, cyanidin, and their underlying mechanisms against Aβ 25-35-induced neuronal cell death in SK-N-SH cells. Aβ 25-35-induced neuronal toxicity is characterized by decrease in cell viability, the release of lactate dehydrogenase (LDH), decrease superoxide dismutase (SOD) activity, increase in reactive oxygen species (ROS) production, morphological alteration, and activation of mitochondrial death pathway. Pretreatment with PRE and cyanidin significantly attenuated Aβ 25-35-induced loss of cell viability, apoptosis, and increase in ROS and RNS production in a dose-dependent manner. In addition, PRE and cyanidin also helped to bring about the downregulation of the expression of Bax, cytochrome c, cleavage caspase-9, and cleavage caspase-3 proteins, and the upregulation of the Bcl-XL protein in cascade. Therefore, it is evident that PRE and its major constituent, cyanidin, were successful in protecting from the cytotoxic effect of Aβ 25-35 through attenuation ROS and RNS production and modulation of mitochondrial death pathway in SK-N-SH cells. This result suggests that PRE and its major constituent, cyanidin, might be beneficial as potential therapeutic agents in preventing neurodegenerative diseases.

Abstract
In the present study, hepatoprotective and antioxidant properties of aqueous extract of Phyllanthus fraternus (AEPF 200, 300, and 400 mg/kg body weight (bw), orally) were investigated against cyclophosphamide (CPA 200 mg/kg, bw, intraperitoneally administered) induced liver damage in mice. Histopathological studies of CPA administration cause liver injury, featuring substantial increase in serum glutamic oxaloacetic transaminase, serum glutamate pyruvate transaminase, lactate dehydrogenase, alkaline phosphatase, acid phosphatase, and total bilirubin. Moreover, CPA intoxication also causes strong oxidative stress, which is evident from significant increase in lipid peroxide level. These changes were coupled with a decline in superoxide dismutase and catalase as well as albumin, cholesterol level, red blood cell (RBC), and white blood cell (WBC) count. AEPF-treated mice displayed a significant inhibition of lipid peroxidation and augmentation of endogenous antioxidants. The study emphasizes the hepatoprotective effect of AEPF against CPA-induced oxidative liver injury, which may serve as a promising medicinal herb in complementary chemotherapeutic modalities.

Abstract
Rice (Oryza sativa L.) can produce black grains as well as white. In black rice, the pericarp of the grain accumulates anthocyanin, which has antioxidant activity and is beneficial to human health. We developed a black rice introgression line in the genetic background of Oryza sativa L. 'Koshihikari', which is a leading variety in Japan. We used Oryza sativa L. 'Hong Xie Nuo' as the donor parent and backcrossed with 'Koshihikari' four times, resulting in a near isogenic line (NIL) for black grains. A whole genome survey of the introgression line using DNA markers suggested that three regions, on chromosomes 1, 3 and 4 are associated with black pigmentation. The locus on chromosome 3 has not been identified previously. A mapping analysis with 546 F2 plants derived from a cross between the black rice NIL and 'Koshihikari' was evaluated. The results indicated that all three loci are essential for black pigmentation. We named these loci Kala1, Kala3 and Kala4. The black rice NIL was evaluated for eating quality and general agronomic traits. The eating quality was greatly superior to that of 'Okunomurasaki', an existing black rice variety. The isogenicity of the black rice NIL to 'Koshihikari' was very high.

Abstract
Black rice (Oryza sativa L.) is often associated with blood lipid control. This study systematically assessed the inhibition of cholesterol absorption in vitro by black rice and explored cholesterol-lowering compounds present in this rice. Our results indicated that black rice extracts (BRE), which were aqueous, ethanol extracts and a fraction of macroporous resin caused the reduction of cholesterol absorption by inhibiting pancreatic lipase, decreasing the micellar cholesterol solubility and suppressing cholesterol uptake in Caco-2 cells. The inhibitory activity was positively associated with anthocyanin (cyanidin-3-glucoside (Cy-3-G) and peonidin-3-glucoside (Pn-3-G)) contents of the extracts. Therefore, the cholesterol absorption inhibiting properties of anthocyanins were further explored. The IC50 values of Cy-3-G and Pn-3-G against pancreatic lipase were 42.53 ± 4.45 and 18.13 ± 4.22 μg mL(-1), respectively. Kinetic analysis suggested that the enzymatic inhibitory mode of Cy-3-G and Pn-3-G belonged to the competitive type. In mixed micelles, Cy-3-G and Pn-3-G dose dependently reduced the solubility of cholesterol. Meanwhile, a potential mechanism of cholesterol reduction by anthocyanins was investigated. Results showed that anthocyanins led to precipitation of cholesterol from micellar solution, which may induce the reduction of cholesterol. In Caco-2 cells, Cy-3-G and Pn-3-G (40 μg mL(-1)) exhibited a significant reduction in cholesterol uptake, and the degree of this reduction was almost the same as that observed in the group treated with Ezetimibe at the same concentration. These findings provide important evidence that anthocyanins may partly contribute to the inhibitory effects of black rice on cholesterol absorption, and thus may be applied for the prevention and treatment of hypercholesterolaemia.

Abstract
Whey fermented liquid (WFL) was studied for its hepatoprotective effects by using chronic alcohol-induced mice. Whey fermented liquid, prepared by inoculating whey with 4% (vol/vol) Lactobacillus casei and then incubating at 41°C for 8h, was used to orally treat alcohol-induced mice at 3 dosages for 5 wk. Ethanol consumption significantly reduced the activity of superoxide dismutase and glutathione peroxidase, while lowering glutathione content and increasing levels of aspartate aminotransferase, alanine aminotransferase, total triglyceride, malondialdehyde, and cytochrome P450 2E1. Treatment with WFL significantly attenuated the increased levels of alanine aminotransferase, aspartate aminotransferase, triglyceride, and cytochrome P450 2E1, while decreasing superoxide dismutase, glutathione peroxidase, malondialdehyde, and glutathione levels. Pathological changes in the livers of mice who had ingested alcohol were improved by the administration of WFL. These results suggest that WFL may exert a protective effect against alcoholic liver disease by increasing antioxidant activity, which supports the use of WFL as an antialcoholic liver disease treatment.

Abstract
Northern Peru represents the center of the Andean "health axis," with roots going back to traditional practices of Cupisnique culture (1000 BC). For more than a decade of research, semistructured interviews were conducted with healers, collectors, and sellers of medicinal plants. In addition, bioassays were carried out to evaluate the efficacy and toxicity of plants found. Most of the 510 species encountered were native to Peru (83%). Fifty percent of the plants used in colonial times have disappeared from the pharmacopoeia. Market vendors specialized either on common and exotic plants, plants for common ailments, and plants only used by healers or on plants with magical purposes. Over 974 preparations with up to 29 different ingredients were used to treat 164 health conditions. Almost 65% of the medicinal plants were applied in these mixtures. Antibacterial activity was confirmed in most plants used for infections. Twenty-four percent of the aqueous extracts and 76% of the ethanolic extracts showed toxicity. Traditional preparation methods take this into account when choosing the appropriate solvent for the preparation of a remedy. The increasing demand for medicinal species did not increase the cultivation of medicinal plants. Most species are wild collected, causing doubts about the sustainability of trade.

Abstract
BACKGROUND Black rice is rich in anthocyanins, especially cyanidin-3-glucoside (C3G). This study examined the effects of a C3G-rich extract from black rice on hyperlipidaemia induced by a high fat/cholesterol diet (HFCD) in rats. RESULTS Male Sprague-Dawley rats were fed either HFCD or HFCD containing 150 mg kg⁻¹ body weight C3G (HFCD+C3G) for 4 weeks. We found that C3G significantly decreased serum levels of total cholesterol, free cholesterol, triglycerides, and free fatty acids in rats fed a HFCD. Similarly, hepatic cholesterol and triglyceride levels and the activities of hepatic lipogenic enzymes (malic enzyme and glucose-6-phosphate dehydrogenase) were significantly reduced by C3G supplementation. CONCLUSION These results suggest that C3G can ameliorate HFCD-induced hyperlipidaemia in part by modulating the activities of hepatic lipogenic enzymes.

Abstract
Black soybean seed coat is a rich source of polyphenols that have been reported to have various physiological functions. The present study investigated the potential protective effects of polyphenolic extracts from black soybean seed coat on DNA damage in human hepatoma HepG2 cells and ICR mice. The results from micronucleus (MN) assay revealed that black soybean seed coat extract (BE) at concentrations up to 25μg/mL was non-genotoxic. It is noteworthy that BE (at 4.85μg/mL) and its main components, procyanidins (PCs) and cyanidin 3-glucoside (C3G), at 10μM significantly reduced the genotoxic effect induced by benzo[a]pyrene [B(a)P]. To obtain insights into the underlying mechanism, we investigated BE and its main components on drug-metabolizing enzyme expression. The results of this study demonstrate that BE and its main components, PCs and C3G, down-regulated B(a)P-induced cytochrome P4501A1 (CYP1A1) expression by inhibiting the transformation of aryl hydrocarbon receptor. Moreover, they increased expression of detoxifying defense enzymes, glutathione S-transferases (GSTs) via increasing the binding of nuclear factor-erythroid-2-related factor 2 to antioxidant response elements. Collectively, we found that PCs and C3G, which are the main active compounds of BE, down-regulated CYP1A1 and up-regulated GST expression to protect B(a)P-induced DNA damage in HepG2 cells and ICR mice effectively.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Long-term excess alcohol exposure leads to alcoholic liver disease (ALD)-a global health problem without effective therapeutic approach. ALD is increasingly considered as a complex and multifaceted pathological process, involving oxidative stress, inflammation and excessive fatty acid synthesis. Over the past decade, herbal medicines have attracted much attention as potential therapeutic agents in the prevention and treatment of ALD, due to their multiple targets and less toxic side effects. Several herbs, such as Cnidium monnieri (L.) Cusson (Apiaceae), Curcuma longa L. (Zingiberaceae) and Pueraria lobata (Willd.) Ohwi (Leguminosae), etc., have been shown to be quite effective and are being widely used in China today for the treatment of ALD when used alone or in combination. AIM OF THE REVIEW To review current available knowledge on herbal medicines used to prevent or treat ALD and their underlying mechanisms. MATERIALS AND METHODS We used the pre-set searching syntax and inclusion criteria to retrieve available published literature from PUBMED and Web of Science databases, all herbal medicines and their active compounds tested on ALD induced by both acute and chronic alcohol ingestion were included. RESULTS A total of 40 experimental studies involving 34 herbal medicines and (or) active compounds were retrieved and reviewed. We found that all reported extracts and individual compounds from herbal medicines/natural plants could be beneficial to ALD, which might be attributed to regulate multiple critical targets involved in the pathways of oxidation, inflammation and lipid metabolism. CONCLUSIONS Screening chemical candidate from herbal medicine might be a promising approach to drug discovery for the prevention or treatment of ALD. However, further studies remain to be done on the systematic assessment of herbal medicines against ALD and the underlying mechanisms, as well as their quality control studies.

Abstract
Black rice (Oryza sativa L. Japonica) contains high levels of anthocyanins in the pericarp and is considered an effective health-promoting food. Several studies have identified the molecular species of anthocyanins in black rice, but information about the localization of each anthocyanin species is limited because methodologies for investigating the localization such as determining specific antibodies to anthocyanin, have not yet been developed Matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS) is a suitable tool for investigating the localization of metabolites. In this study, we identified 7 species of anthocyanin monoglycosides and 2 species of anthocyanin diglycosides in crude extracts from black rice by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) analysis. We also analyzed black rice sections by MALDI-IMS and found 2 additional species of anthocyanin pentosides and revealed different localization patterns of anthocyanin species composed of different sugar moieties. Anthocyanin species composed of a pentose moiety (cyanidin-3-O-pentoside and petunidin-3-O-pentoside) were localized in the entire pericarp, whereas anthocyanin species composed of a hexose moiety (cyanidin-3-O-hexoside and peonidin-3-O-hexoside) were focally localized in the dorsal pericarp. These results indicate that anthocyanin species composed of different sugar moieties exhibit different localization patterns in the pericarp of black rice. This is the first detailed investigation into the localization of molecular species of anthocyanins by MALDI-IMS.

Abstract
In this paper, the hepatoprotective effects of 2',4'-dihydroxy-6'-methoxy-3',5'-dimethylchalcone (DMC) on CCl(4)-induced acute liver injury in Kunming mice were investigated. DMC was administered intraperitoneally (ip) (5, 10, or 20 mg/kg of body weight) for 7 days prior to the administration of CCl(4) (0.1%, ip). Pretreatment with DMC significantly decreased activities of serum hepatic enzymes, namely alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, alkaline phosphatase, γ-glutamyl transferase, and total bilirubin, and decreased the elevation of lipid peroxidation, malondialdehyde, reactive oxygen species, and protein carbonyl content. Pretreatment with DMC markedly increased activities of enzymatic antioxidants such as superoxide dismutase, catalase, glucose-6-phosphate dehydrogenase, glutathione peroxidase, glutathione S-transferase, and glutathione reductase and increased levels of nonenzymatic antioxidant markers such as reduced glutathione, total sulfhydryl groups, vitamin C, and vitamin E in liver. These results combined with liver histopathology demonstrate that DMC has potential hepatoprotective effects, which may be related to the attenuation of oxidative stress, accelerating the antioxidant cascade and inhibition of lipid peroxidation.

Phytother Res 2011; 26:106-12.

Abstract
Hull blackberries were purified using solid phase extraction to obtain anthocyanin-rich methanol fractions. This method concentrated phenolics and anthocyanins, recovering 97% and 76% of the total yield in puree or powder extracts, respectively, which represented a 24-63 fold increase of the total antioxidant capacity when compared with either the water fraction or the original extract. The ability of these fractions to protect primary keratinocytes against UV-induced oxidative damage was assessed. Anthocyanin-rich methanol fractions derived from either blackberry powder or puree exhibited strong antioxidant properties, protecting against UV-induced ROS nearly as efficiently as N-acetyl cysteine. Furthermore, the fractions up-regulated the expression of catalase, MnSOD, Gpx1/2 and Gsta1 antioxidant enzymes. Thus, it is concluded that blackberry extracts may protect keratinocytes against UV-mediated oxidative damage.

Abstract
This study evaluated the protective effects of purple rice ( Oryza sativa L.) bran extract (PRE) and its major anthocyanidins (cyanidin and peonidin) against light-induced retinal damage. In an in vitro experiment, cultured murine photoreceptor cells (661W) were damaged by a 24 h exposure to light. Viability of 661W after light treatment, assessed by the tetrazolium salt (WST-8) assay and Hoechst 33342 nuclear staining, was improved by the addition of PRE, cyanidin, and peonidin. Intracellular radical activation in 661W, evaluated using the reactive oxygen species (ROS) sensitive probe 5-(and 6)-chloromethyl-2,7-dichlorodihydrofluorescein diacetate acetyl ester (CM-H(2)DCFDA), was reduced by PRE and its anthocyanidins. Electron spin resonance (ESR) measurements showed that PRE, peonidin, and cyanidin all exhibited radical scavenging activities against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, superoxide anion radical ((•)O(2)(-)), and hydroxyl radical ((•)OH). In an in vivo mouse experiment, intravitreous injection of PRE significantly suppressed photoreceptor degeneration induced by exposure to light as revealed by histological analysis using hematoxylin-eosin staining. These findings suggest that PRE and its anthocyanidins possess protective effects with antioxidation mechanism in both in vitro and in vivo models of retinal diseases.
