Effects of drying methods on the physicochemical characteristics and bioactivities of polyphenolic-protein-polysaccharide conjugates from Hovenia dulcis. Int J Biol Macromol 2019; 148:1211-1221. [PMID: 31758998 DOI: 10.1016/j.ijbiomac.2019.10.211] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2019] [Revised: 10/08/2019] [Accepted: 10/24/2019] [Indexed: 02/06/2023]
Abstract
Four drying methods, including freeze drying, hot air drying, vacuum drying, microwave drying at 400, 600, and 800 W, were applied to dry the peduncles of Hovenia dulcis. Then the effects of different drying methods on physicochemical characteristics and bioactivities of polyphenolic-protein-polysaccharides conjugates extracted from H. dulcis (PPPs) were investigated and compared. Results showed that different drying methods affected the physicochemical characteristics and bioactivities of PPPs. Noticeable variations in extraction yields, contents of total proteins, contents of total polyphenolics, contents of total flavonoids, contents of uronic acids, molecular weights, apparent viscosities, molar ratios of constituent monosaccharides, ratios of constituent amino acids, and degrees of esterification were observed in PPPs obtained by different drying methods. Besides, a total of 13 phenolic compounds in PPPs were identified by UPLC-ESI-QTOF-MS. In addition, PPPs, especially PPP-M6 and PPP-V dried by microwave drying at 600 W and vacuum drying, respectively, exhibited remarkable antioxidant activities, antiglycation activities, and inhibitory activities on α-amylase and α-glucosidase. Results suggested that the microwave drying and vacuum drying techniques could be appropriate drying methods before extraction of PPPs with high bioactivities for applications in the functional food and medicine industries.

Abstract
Corn silk polysaccharides (CSPs) were extracted from the corn silk cultivated in Jilin province, China, where is one of the golden corn belts worldwide. Three fractions (CSP-1, CSP-2 and CSP-3) were obtained by DEAE-52 cellulose and the former two fractions were further purified by Sephadex G-150 column chromatography to obtain CSP-S-1 and CSP-S-2. The molecular weights of CSP-S-1 and CSP-S-2 were calculated to be 586 kDa and 813 kDa, respectively. CSP-S-1 was composed of galactose, arabinose, xylose and rhamnose at a molar ratio of 4.16:1.00:1.01:6.32 and CSP-S-2 was composed of galactose, arabinose, glucose and rhamnose at a molar ratio of 8.71:3.58:0.169:1.00. CSP-S-2 outperformed CSP-S-1 in scavenging DPPH, ABTS and hydroxyl radicals, and significantly inhibited the proliferation of HeLa cells. IR and NMR analysis indicated that CSP-S-2 was pyranose. CSP-S-2 consisted of 1 → 4 and 1 → 6 linkages and exhibited a triple helix configuration. In summary, CSP-S-2 possesses high potential to be developed as a novel antioxidant and anti-cervical cancer agent.

Abstract
Hyperlipidemia, a very common disease throughout the world, usually gives rise to severe liver damages. The current experiment was to investigate the antihyperlipidemic and hepatoprotective properties of alkali- and enzyme-extractable Dictyophora indusiata polysaccharides (Al-DPS and En-DPS) on the hyperlipidemic mice. The results of animal experiment in vivo showed that treatment with Al-DPS or En-DPS could improve the excessive level of lipid profiles in serum and liver, as well as strengthen antioxidant status. In addition, the histopathological observations of liver testified that polysaccharides were capable of attenuating hepatic cell injury. The primary structural features of Al-DPS and En-DPS were demonstrated by HPGPC, HPLC, FT-IR and NMR. Glucose tolerance test manifested that polysaccharides were able to restrain the rise of blood sugar. The results indicated that Al-DPS and En-DPS may be considered as novel compounds to treat hyperlipidemia and also act as hepatoprotective agents.

Abstract
Fatty liver (FLD) disease is a consequence of metabolic syndrome, which is a health problem worldwide with a phenomenal rise in prevalence. In this study, two hepatoprotective polysaccharide-peptides were extracted from the mushroom Auricularia polytricha followed by chromatographic fractionation of the extract on the ion exchanger DEAE-cellulose and gel filtration on Sephadex-200 to yield two purified fractions: APPI and APPII. The monosaccharide compositions, FT-IR, N-terminal sequences, internal peptide sequences and molecular weights of the two fractions were determined. Furthermore, their hepatoprotective effect on human hepatoma HepG2 cells in vitro and in an animal model of fatty liver disease was evidenced by the findings that APPI and APPII diminished lipid deposit in cells, blood and the liver, increased cellular antioxidant activity and viability, and protected the liver against injury. The mechanistic study revealed that APPI and APPII activated the adiponectin pathway, up-regulated expression of genes controlling free fatty acid (FFA) oxidation, such as AMPK, CPTl, ACOX1 and PPARα genes, enhanced lipid metabolism, preserved hepatic function, promoted the antioxidant defense system and reduced lipid peroxidation. Hence the bioactive compounds of A. polytricha could serve as therapeutic agents in the food and pharmaceutical industries.

Abstract
Acute liver injury is a common consequence of taking overdose of acetaminophen (APAP). The aim of this study was to evaluate the antioxidant activity and hepatoprotective effect of a mangrove plant Sonneratia apetala fruit extract (SAFE) on APAP-induced liver injury in mice. Mice were orally pretreated with SAFE (100, 200, and 400 mg/kg) daily for one week. The control and APAP groups were intragastrically administered with distilled water, and NAC group was treated with N-Acetyl-L-cysteine (NAC) before APAP exposure. The results manifested that SAFE significantly improved survival rates, attenuated hepatic histological damage, and decreased the alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in serum in APAP-exposed mice. SAFE treatment also increased glutathione (GSH) level and glutathione peroxidase (GSH-Px) activity, enhanced catalase (CAT), and total antioxidant capacity (T-AOC), as well as reducing malondialdehyde (MDA) level in liver. In addition, the formation of tumor necrosis factor-alpha (TNF-α), interleukin 6 (IL-6), and elevation of myeloperoxidase (MPO) in APAP-exposed mice were inhibited after SAFE treatment. And SAFE also displayed high DPPH radical scavenging activity and reducing power in vitro. The main bioactive components of SAFE such as total phenol, flavonoid, condensed tannin, and carbohydrate were determined. The current study proved that SAFE exerted potential protective effect against APAP-induced acute liver injury, which might be associated with the antioxidant and anti-inflammatory activities of SAFE.

Abstract
A new, more effective and environmentally friendly method involving a complex enzyme combined with ultrasonication was employed to extract and isolate three novel polysaccharides (HPS-MCs: HPS-MC, HPS-MC (50%) and HPS-MC (80%)) of Radix Hedysari. Compared with polysaccharides obtained using a traditional extraction method (hot water extraction, HPS-R), the yields and total carbohydrate contents of HPS-MCs were significantly higher. HPS-MC (80%) exhibited relatively strong immunomodulatory activity and a concentration-dependent dose-response relationship under cyclophosphamide (CP)-induced immunosuppressive conditions in mice models. To more comprehensively investigate the relationships between structural characteristics and immunomodulatory activity, HPS-MC (80%) was fractionated into three major homogeneous polysaccharide fractions (HPS-MC (80%)s: HPS-MC (80%)-1, HPS-MC (80%)-2, and HPS-MC (80%)-3). These three homogeneous polysaccharides had different mass percentages of monosaccharides species (rhamnose, arabinose, mannose, glucose, and galactose) by gas chromatography (GC) and different molecular weights and chain conformations by high-performance gel permeation chromatography coupled with multi-angle laser light scattering (HPGPC-MALLS), and promoted macrophage and splenocyte proliferation to different degrees. These findings indicated that HPS-MC (80%) had a prominent potential immune response, especially HPS-MC (80%)-2 and HPS-MC (80%)-3, and might be suitable candidates for functional foods or potential novel immunomodulators.

Abstract
The present work aimed to investigate the antioxidation, hepatic- and renal-protection of water-extractable polysaccharides (WPS) by Dictyophora indusiata fruiting body on high-fat emulsion-induced obese mice. The structural analysis indicated that WPS was the α-configurational heteropolysaccharide with the major monosaccharides of mannose and glucose, and the polydispersity of 1.77. The in vivo results showed that WPS administration could improve obesity-associated hepatic and renal metabolic impairment, reduce body weight and ameliorate oxidative stress of liver and kidney by down-regulating serum enzyme activities and hepatic lipid levels, stabilizing serum lipid status, enhancing antioxidant abilities and decreasing insulin and leptin resistance. The in vitro experiments showed that WPS had potential abilities to scavenge free radicals. The conclusions demonstrated that WPS might be used as a salutary food and natural medicine for preventing obesity-associated damage and its complications.

Abstract
Longan (Dimocarpus longan Lour.) pericarp, the main by-product of aril and pulp processing, is abundant in phenolic compounds and worthy of further utilization. The present work firstly reported HPLC analysis and in vitro antioxidant evaluation of longan (cv. Shixia) pericarp-derived phenolics (LPPs), the purified longan pericarp extract (LPE), as well as their cytotoxic effect on lung cancer cell line, A549. The results indicated that the purified LPE had significant amounts of phenolics, with content of 57.8 ± 0.6 mg of gallic acid equivalents per gram of dry longan pericarp (mg GAE·g-1 DLP), which consisted of six phenolic compounds (A⁻F), including protocatechuic acid (A), isoscopoletin (B), quercetin (C), ellagic acid (D), corilagin (E), and proanthocyanidins C1 (F). Antioxidant assays showed that LPPs (10 μM) and LPE (1.0 mg·mL-1) had certain antioxidant activities, in which corilagin (E) possessed the best DPPH radical scavenging rate 71.8 ± 0.5% and •OH inhibition rate 75.9 ± 0.3%, and protocatechuic acid (A) exhibited the strongest Fe2+ chelating ability 36.4 ± 0.7%. In vitro cytotoxic tests suggested that LPPs had different effect on A549 cell line, in which corilagin (E) exhibited potent cytotoxicity with an IC50 value of 28.8 ± 1.2 μM. These findings were further confirmed by cell staining experiments.

Abstract
In the present work, we investigated the anti-hyperlipidemic, antioxidant and organic protection effects of acidic-extractable Dictyophora indusiata polysaccharides (Ac-DPS) on hyperlipidemic mice induced by high-fat emulsion. The results demonstrated that Ac-DPS had impressive abilities to mitigate oxidative stress by increasing the activities of antioxidant enzyme and reducing the contents of lipid peroxide. Moreover, lipid levels in serum were returned to normal status. Besides, Ac-DPS exhibited potential hepatic and renal protection effects reflected by decreasing serum enzyme activities, lowering TBIL, UREA and CREA levels and increasing ALB content. At the same time, histopathological observations proved protective effects of Ac-DPS on organs. Subsequently, the physical properties of polysaccharide were also investigated by HPGPC and FT-IR. The above consequences confirmed the important role of Ac-DPS as a functional food and natural medicine in the fight against oxidative stress and the prevention of hyperlipidemia.

Abstract
Increasing evidence has shown that dicaffeoylquinic acids (DiCQAs) have anti-inflammatory activity. However, the underlying molecular mechanisms of the anti-inflammatory effects of DiCQAs are still unclear. In the present study, the anti-inflammatory effects of DiCQAs from the leaves of Ilex kudingcha and the potential molecular mechanisms on LPS-induced inflammatory responses in RAW264.7 macrophage cells were investigated. The results showed that pretreatment with DiCQAs could suppress the production of NO, PGE2 and also pro-inflammatory cytokines TNF-α, IL-1β and IL-6, and the mRNA expression of two major inflammatory mediators of COX-2 and iNOS. The phosphorylated IκBα, ERK, JNK and p38 proteins in LPS-treated cells were significantly increased, which could be reversed by pretreatment with DiCQAs in a concentration-dependent manner. Taken together, the results suggest that DiCQAs from I. kudingcha have potent anti-inflammatory effects on LPS-induced inflammatory responses by inhibiting the NF-κB and MAPKs pathways and may be a prophylactic for inflammation.

Abstract
Tea and coffee are caffeinated beverages commonly consumed around the world in daily life. Tea from Camellia sinensis is widely available and is a good source of caffeine and other bioactive compounds (e.g., polyphenols and carotenoids). Other tea-like beverages, such as those from the genus Ilex, the large-leaved Kudingcha (Ilex latifolia Thunb and Ilex kudingcha C.J. Tseng), Yerba Mate (Ilex paraguariensis A. St.-Hil), Yaupon Holly (Ilex vomitoria), and Guayusa (Ilex guayusa Loes) are also traditional drinks, with lesser overall usage, but have attracted much recent attention and have been subjected to further study. This review summarizes the distribution, composition, and health benefits of caffeinated beverages from the genus Ilex. Plants of this genus mainly contain polyphenols and alkaloids, and show diverse health benefits, which, as well as supporting their further popularization as beverages, may also lead to potential applications in the pharmaceutical or nutraceutical industries.

Abstract
To study the antioxidant capacity of Astragalus polysaccharides (APS) with different molecular weights, we used hydrogen peroxide to degrade original Astragalus polysaccharide (APS0) with an initial molecular weight of 11.03 kDa and obtained three degraded polysaccharides with molecular weights of 8.38 (APS1), 4.72 (APS2), and 2.60 kDa (APS3). The structures of these polysaccharides were characterized by 1H NMR, 13C NMR, FT-IR, and GC/MS. The degradation process did not cause significant changes in the main chain structure of APS. The monosaccharide component of APS before and after degradation was slightly changed. The antioxidant ability in vitro (removing hydroxyl and ABTS radicals and reducing ability) and in cells (superoxide dismutase and malondialdehyde generation) of these polysaccharides is closely related to their molecular weight. If the molecular weight of APS is very high or low, it is not conducive to their activity. Only APS2 with moderate molecular weight showed the greatest antioxidant activity and ability to repair human kidney epithelial (HK-2) cells. Therefore, APS2 can be used as a potential antistone polysaccharide drug.

Abstract
The aims of this work were to investigate the antioxidant, anti-hyperlipidemia and hepatic protection of Morehella esculenta polysaccharide (MPS) from fruiting body and its enzyme-assisted MPS (EnMPS). The in vitro scavenging rates of EnMPS at 600 mg/L on superoxide, hydroxyl and 1,1‑diphenyl‑2‑pyrazole hydrazide (DPPH) radicals were 76.92 ± 2.61%, 66.74 ± 2.56% and 75.78 ± 2.4%, higher than those of MPS, respectively. Animals experiments showed that the EnMPS exhibited superior abilities of reducing hepatic lipid levels by monitoring the serum enzyme activities (ALP, ALT, ALB and AST) and serum lipid levels (CK, TC, TG, HDL-C, LDL-C and LDH), enhancing the hepatic antioxidant enzymes (FFA, SOD, CAT and T-AOC) and decreasing the lipid peroxidation (MDA and MPO). The results suggested that the EnMPS can act as a natural candidate for developing drugs to reduce blood lipids, resist oxidation and protect the liver.

Abstract
Our recent study found that antioxidative activity of phenolic compounds extracted from germinated chickpea was boosted in both in vitro assays and oil-in-water emulsions [ Xu et al. Food Chem. 2018 , 250 , 140 ]. The purpose of this study was to elucidate the mechanism by which germination enhances the antioxidative activity of the phenolic compounds extracted from chickpea. Liquid chromatography coupled with electrospray-ionization quadrupole time-of-flight mass spectrometry (LC-ESI-QTOF-MS) and size-exclusion chromatography with multiangle-light-scattering and refractive-index detection (SEC-MALS-RI) were employed to evaluate the phenolic composition of soluble phenolic compounds (free and bound) and molar masses of soluble bound phenolic compounds, respectively, over 6 days of germination. According to principal-component analysis of the interrelationship between germination time and phenolic composition, it is revealed that protocatechuic acid 4- O-glucoside and 6-hydroxydaidzein played a pivotal role in the soluble free phenolic compounds, whereas gentisic acid and 7,3',4'-trihydroxyflavone were important in the soluble bound phenolic compounds. Molar masses of soluble bound phenolic compounds were increased after 6 days of germination. Protective and dual antioxidative effects were proposed to explicate how the antioxidative activity of soluble bound phenolic compounds in oil-in-water emulsions was improved with germination.

Abstract
BACKGROUND Guayusa (Ilex guayusa Loes.) leaves, native of the Ecuadorian Amazon, are popularly used for preparing teas. This study aimed to assess the influence of leaf age on the phenolic compounds and carotenoids and the bioactivity and digestibility (in vitro) of aqueous and hydroalcoholic leaf extracts. RESULTS In total, 14 phenolic compounds were identified and quantified. Chlorogenic acid and quercetin-3-O-hexose were the main representatives of the hydroxycinnamic acids and flavonols respectively. Seven carotenoids were quantified, lutein being the main compound. Ripening affected phenolic content significantly, but there was no significant difference in carotenoid content. Antioxidant capacity, measured by the DPPH• method, was also significantly affected by leaf age. The measurement of in vitro digestibility showed a decrease in phenolic content (59%) as well as antioxidant capacity, measured by the ABTS•+ method, in comparison with initial conditions of the guayusa infusion. Antibacterial and anti-inflammatory activities were assayed with young leaves owing to their higher phenolic contents. Guayusa did not show any antibacterial activity against Escherichia coli ATCC 25922 or Staphylococcus aureus ATCC 25923. Finally, the hydroalcoholic and aqueous extracts exhibited high in vitro anti-inflammatory activity (>65%). CONCLUSION Young guayusa leaves have potential applications as a functional ingredient in food and pharmaceutical industries. © 2017 Society of Chemical Industry.

Abstract
The objective of this study was to analyse the structure of CPP-2, and to observe the pharmacological effects of CPP-2 on lipid metabolism and oxidative stress. CPP-2, eluted as two main fractions comprised of two polysaccharides with Mw of 307 and 3.7kDa, was mainly consisted of rhamnose, mannose, glucose and galactose in a molar ratio of 1.00:0.78:3.22:0.45. The results showed that treatment with CPP-2 could improve blood lipid levels (TC, TG, HDL-C and LDL-C), liver lipid levels (TC and TG) and antioxidant status (SOD, T-AOC, GSH-PX, MDA and LPO). In addition, the histopathological observations of mice livers and the GPT activities indicated that CPP-2 could attenuate liver cell injury. The present findings demonstrated that CPP-2 might be effective in lowering lipid and protecting against HFE-induced hyperlipidemia and non-alcoholic fatty liver.

Abstract
A novel polysaccharide FVPB2 was purified from fruiting bodies of Flammulina velutipes. Its structure was elucidated by monosaccharide composition and methylation analyses, UV-Visible and FTIR spectroscopy as well as NMR. FVPB2 was a homogeneous heteropolysaccharide (molecular weight ~ 1.50 × 104 Da) containing D-galactose, D-mannose, L-fucose, and D-glucose at molar ratio of 1.9:1.2:1:2.5. In vitro immunomodulatory studies showed FVPB2 induced proliferation of mouse spleen lymphocytes in a dose-dependent manner. The levels of IgM and IgG, secreted by B cells, increased after FVPB2 treatment. So FVPB2 has potential to be a new important immunomodulatory nutraceutical.

Abstract
Digestion and fermentation in vitro of polysaccharides from bee collected pollen of Chinese wolfberry (WBPPS) were investigated in the present study. It was found that WBPPS mainly consisted of mannose, ribose, rhamnose, galacturonic acid, glucose, galactose, xylose, and arabinose in a molar ratio of 0.38:0.09:0.17:0.64:0.22:0.67:0.08:1.03, respectively. WBPPS was not affected by human saliva. The fraction A (molecular weight 1340 kDa) of WBPPS was not broken down in simulated gastric and small intestinal juices, while the small fraction B (molecular weight 523 kDa) of WBPPS was degraded. Moreover, fermentation in vitro revealed that WBPPS could significantly enhance the production of short-chain fatty acids and modulate gut microbiota composition via increasing the relative abundances of genera Prevotella, Dialister, Megamonas, Faecalibacterium, and Alloprevotella and decreasing the numbers of genera Bacteroides, Clostridium XlVa, Parabacteroides, Escherichia/Shigella, Phascolarctobacterium, Parasutterella, Clostridium sensu stricto, and Fusobacterium.

Abstract
The objectives of the present study were to characterize the chemical composition, antioxidant activity and hepatoprotective effect of the polysaccharides from Taishan Pinus massoniana pollen (TPPPS). HPLC analysis showed that TPPPS was an acidic heteropolysaccharide with glucose and arabinose as the main component monosaccharides (79.6%, molar percentage). Fourier transform-infrared spectroscopy (FT-IR) analysis indicated that the spectra of TPPPS displayed infrared absorption peaks characteristic of polysaccharides. In in vitro assays TPPPS exhibited different degrees of dose-dependent antioxidant activities , and this was further verified by suppression of CCl4-induced oxidative stress in the liver with three tested doses of TPPPS (100, 200, and 400 mg/kg bw) in rats. Pretreatment with TPPPS significantly decreased the levels of alanine aminotransferase (AST), aspartate aminotransferase (ALT), alkaline phosphatase (ALP), lactic dehydrogenase (LDH) and malondialdehyde (MDA) against CCl4 injuries, and elevated the activities of superoxide dismutase (SOD) as well as glutathione peroxidase (GSH-Px). Histopathological observation further confirmed that TPPPS could protect the liver tissues from CCl4-induced histological alternation. These results suggest that TPPPS has strong antioxidant activities and significant protective effect against acute hepatotoxicity induced by CCl4. The hepatoprotective effect may partly be related to its free radical scavenging effect, increasing antioxidant activity and inhibiting lipid peroxidation.

Abstract
Dietary polyphenols have been considered as novel prebiotics, and polyphenols could exert their functions through modulating intestinal microbiota. The diverse bioactivities of kudingcha could derive from its phenolic compounds, but the effects of dicaffeoylquinic acids (diCQAs) from Ilex kudingcha on intestinal microbiota have not been investigated. In the present study, high-throughput sequencing and anaerobic fermentation in vitro were utilized to investigate the microecology-modulating function of I. kudingcha diCQAs. As a result, diCQAs raised the diversity and exhibited a more considerable impact than a carbon source on the microbial profile. DiCQAs increased the relative abundances of Alistipes, Bacteroides, Bifidobacterium, Butyricimonas, Clostridium sensu stricto, Escherichia/Shigella, Parasutterella, Romboutsia, Oscillibacter, Veillonella, Phascolarctobacterium, Lachnospiracea incertae sedis, Gemmiger, Streptococcus, and Haemophilus and decreased the relative abundances of Ruminococcus, Anaerostipes, Dialister, Megasphaera, Megamonas, and Prevotella. DiCQAs also affected the generation of short-chain fatty acids through microbiota. The contents of acetic and lactic acids were raised, while the production of propionic and butyric acids was reduced. Conclusively, diCQAs from I. kudingcha had significant modulating effects on intestinal microbiota in vitro, which might be the fundamental of diCQAs exerting their bioactivities.

Abstract
Previous studies have indicated that the Ilex genus exhibits antioxidant, neuroprotective, hepatoprotective, and anti-inflammatory activities. However, the pharmacologic action and mechanisms of Ilex cornuta against cardiac diseases have not yet been explored. The present study was designed to investigate the antioxidant and cardioprotective effects of Ilex cornuta root with in vitro and in vivo models. The anti-oxidative effects of the extract of Ilex cornuta root (ICR) were measured by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging and MTT assays as well as immunoassay. Furthermore, a rat model of myocardial ischemia was established to investigate the cardioprotective effect of ICR in vivo. Eight compounds were isolated and identified from ICR and exhibited DPPH free-radical scavenging activities. They also could increase cell viability and inhibit morphological changes induced by H2O2 or Na2S2O4 in H9c2 cardiomyocytes, followed by increasing the SOD activities and decreasing the MDA and ROS levels. In addition, it could suppress the apoptosis of cardiomyocytes. In the rat model of myocardial ischemia, ICR decreased myocardial infarct size and suppressed the activities of LDH and CK. Furthermore, ICR attenuated histopathological alterations of heart tissues and the MDA levels, while increasing SOD activities in serum. In conclusion, these results suggest that ICR has cardioprotective activity and could be developed as a new food supplement for the prevention of ischemic heart disease.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Anoectochilus roxburghii (Wall.) Lindl. is traditionally used for the treatment of various types of chronic and acute hepatitis in China. Considering that Anoectochilus roxburghii polysaccharide (ARPT) is the main constituent of Anoectochilus roxburghii, the present study was designed to investigate the hepatoprotective effect of ARPT and its possible mechanism in carbon tetrachloride (CCl4)-induced mice. MATERIAL AND METHODS The hepatoprotective activity of ARPT (150, 300 and 500mg/kg) were investigated on CCl4-induced acute liver damage in mice. The activities of alanine transaminase (ALT), aspartate transaminase (AST) were determined in serum. The hepatic levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) were measured in liver homogenates. The levels of cytochrome P450 sub family 2E1 (CYP2E1), tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-2 (MIP-2), KC (Murine IL-8 ortholog), transforming growth factor-beta1 (TGF-β1), Bcl-2 and Bax were measured by quantitative real-time polymerase chain reaction (qRT-PCR). The expressions of CYP2E1, nuclear factor-kappa B (NF-κB) p65 and caspase-3 were evaluated by western blot assays. The hepatic levels of TNF-α, IL-6, MIP-2 and TGF-β1 were measured by enzyme-linked immunosorbent assay (ELISA). Furthermore, histopathological observation and terminal-deoxynucleoitidyl transferase mediated nick end labeling assay (TUNEL) were carried out on the separated livers of mice. RESULTS ARPT significantly decreased serum ALT and AST activities, hepatic MDA level, and markedly enhanced antioxidant enzyme (SOD, CAT and GSH-Px) activities and GSH level in hepatic tissue, in a dose-dependent manner, when compared to the model group. Histopathological observation revealed the hepatoprotective effect of ARPT against the damage. Furthermore, ARPT remarkably inhibited CYP2E1 mRNA expression, decreased NF-κB p65 expression and therefore to prevent the secretion of pro-inflammatory cytokines (TNF-α and IL-6) and chemokines (MCP-1, MIP-2 and KC), suppressed TGF-β1 expression and hepatocytes apoptosis. Moreover, ARPT could prevent DNA fragmentation based on TUNEL assay results. CONCLUSION These findings suggested that ARPT possessed hepatoprotective effect against CCl4-induced hepatotoxicity in mice and the action might in part be through reducing oxidative stress, inflammation and apoptosis.

Abstract
Monocaffeoylquinic acids (mono-CQAs) can be hydrolyzed or metabolized by pancreatin, intestinal brush border esterase, and microbiota in the colon. Data about the conversion of dicaffeoylquinic acids (diCQAs) in digestion are scarce. The diCQA-rich fraction including 3,4-, 3,5-, and 4,5-diCQAs was prepared from Ilex kudingcha, and the conversion in simulated gastricintestine was investigated. Artificial saliva, gastric and pancreatic fluids, Caco-2 monolayer cells, and anaerobic fermentation model were utilized to mimic digestions of the oral cavity, stomach, small intestine, and colon in vitro. The results revealed that diCQAs remained intact in simulated saliva, gastric, and pancreatic fluids and within Caco-2 cells. In anaerobic fermentation with human fecal slurry, diCQAs were hydrolyzed to mono-CQAs and caffeic acid, which were further metabolized to caffeic acid and dihydrocaffeic acid, respectively. The hydrolysis of diCQAs depended on the chemical structures, carbohydrates in the culture medium, and microbial compositions. Our research demonstrated that hydrolysis of diCQAs happened in the colon by intestinal microbiota.

The optimization extraction, preliminary characterization and bioactivities of Ligularia hodgsonii polysaccharides were investigated. Based on single-factor experiments and orthogonal array test, the optimum extraction conditions were obtained as follows: extraction time 3 h, temperature 85 °C, water/raw material ratio 36. Further Sevag deproteinization and dialysis yielded the dialyzed Ligularia hodgsonii polysaccharides (DLHP, 19.2 ± 1.4 mg/g crude herb). Compositional analysis, size-exclusion chromatography connected with multi-angle laser light-scattering and refractive index (SEC-MALLS-RI), Fourier transform infrared (FT-IR) and 1H nuclear magnetic resonance (NMR) spectroscopy were employed for characterization of the polysaccharides. DLHP was found to have a major component with a weight-average molecular weight of 1.17 × 105 Da, mainly comprising of glucose, galactose, arabinose, mannose, rhamnose, glucuronic acid and galacturonic acid. By in vitro antioxidant activity assays, DLHP presented remarkable scavenging capacities towards 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and hydroxyl radicals, and ferrous ions chelating ability. Moreover, it exhibited appreciable anti-hyperglycemic activity as demonstrated by differential inhibition of α-glucosidase and α-amylase. The results indicated that DLHP could potentially be a resource for antioxidant and hypoglycemic agents.
