Abstract
Aging is a process characterized by accumulating degenerative damages, resulting in the death of an organism ultimately. The main goal of aging research is to develop therapies that delay age-related diseases in human. Since signaling pathways in aging of Caenorhabditis elegans (C. elegans), fruit flies and mice are evolutionarily conserved, compounds extending lifespan of them by intervening pathways of aging may be useful in treating age-related diseases in human. Natural products have special resource advantage and with few side effect. Recently, many compounds or extracts from natural products slowing aging and extending lifespan have been reported. Here we summarized these compounds or extracts and their mechanisms in increasing longevity of C. elegans or other species, and the prospect in developing anti-aging medicine from natural products.

Abstract
With the rising awareness of a healthy lifestyle, natural functional foods have gained much interest as promising alternatives to synthetic functional drugs. Recently, wild Agaricus bisporus (Lange) Sing. Chaidam has been found and artificially cultivated for its thick fresh body and excellent taste, with its antioxidant and anti-hypoxic abilities unknown. In this work, the antioxidant potential of its methanolic, 55% ethanolic, aqueous extracts and crude polysaccharide was evaluated in different systems. The results showed that polysaccharide was the most effective in scavenging ability on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydroxyl radicals, metal chelating activity and reducing power, with EC50 values of 0.02, 2.79, 1.29, and 1.82 mg/mL, respectively. Therefore, we further studied the anti-hypoxic activity of crude polysaccharide. The results turned out that polysaccharide (300 mg/kg) prolonged the survival time, decreased the blood urea nitrogen and lactic acid content as well as increased the liver glycogen significantly, compared with the blank control and the commercialized product Hongjingtian (p < 0.05). With such excellent activities, we purified the polysaccharide and analyzed its molecular weight (120 kDa) as well as monosaccharide components (glucose, fructose and mannose). This study indicated that wild Agaricus bisporus (Lange) Sing. Chaidam had strong potential to be exploited as an effective natural functional food to relieve oxidative and hypoxia stresses.

Abstract
Phytochemicals are structurally diverse secondary metabolites synthesized by plants and also by non-pathogenic endophytic microorganisms living within plants. Phytochemicals help plants to survive environmental stresses, protect plants from microbial infections and environmental pollutants, provide them with a defense from herbivorous organisms and attract natural predators of such organisms, as well as lure pollinators and other symbiotes of these plants. In addition, many phytochemicals can extend longevity in heterotrophic organisms across phyla via evolutionarily conserved mechanisms. In this review, we discuss such mechanisms. We outline how structurally diverse phytochemicals modulate a complex network of signaling pathways that orchestrate a distinct set of longevity-defining cellular processes. This review also reflects on how the release of phytochemicals by plants into a natural ecosystem may create selective forces that drive the evolution of longevity regulation mechanisms in heterotrophic organisms inhabiting this ecosystem. We outline the most important unanswered questions and directions for future research in this vibrant and rapidly evolving field.

Abstract
Ageing is a complex molecular process driven by diverse molecular pathways and biochemical events that are promoted by both environmental and genetic factors. Specifically, ageing is defined as a time-dependent decline of functional capacity and stress resistance, associated with increased chance of morbidity and mortality. These effects relate to age-related gradual accumulation of stressors that result in increasingly damaged biomolecules which eventually compromise cellular homeostasis. Nevertheless, the findings that genetic or diet interventions can increase lifespan in evolutionarily diverse organisms indicate that mortality can be postponed. Natural compounds represent an extraordinary inventory of high diversity structural scaffolds that can offer promising candidate chemical entities in the major healthcare challenge of increasing health span and/or delaying ageing. Herein, those natural compounds (either pure forms or extracts) that have been found to delay cellular senescence or in vivo ageing will be critically reviewed and summarized according to affected cellular signalling pathways. Moreover, the chemical structures of the identified natural compounds along with the profile of extracts related to their bioactive components will be presented and discussed. Finally, novel potential molecular targets for screening natural compounds for anti-ageing activity, as well as the idea that anti-ageing interventions represent a systemic approach that is also effective against age-related diseases will be discussed.

Abstract
Crude water-soluble Chinese truffle Tuber indicum polysaccharide (TIP) was extracted from the fruiting bodies with water and then successively purified by DEAE-cellulose 52 and Sephadex G-100 column chromatography, yielding two major polysaccharide fractions: TIP1-1 and TIP2-1. High-performance gel permeation chromatography analysis showed that the average molecular sizes of TIP1-1 and TIP2-1 were approximately 1.75×10(4) Da and 5.73×10(3) Da, respectively. Monosaccharide component analysis by gas chromatography indicated that TIP1-1 was composed of mannose, glucose, galactose, and rhamannose in the respective molar ratio of 3.93:1.24:0.75:1.26 and that TIP2-1 contained mannose, glucose, and arabinose in the respective molar ratio of 5.27:1.44:0.43. The antioxidant activity analyses revealed that TIP1-1 and TIP2-1 possessed considerable antioxidant activity. Compared with TIP1-1, which has a higher molecular weight and contains no uronic acid, TIP2-1 exhibited a protective effect on PC12 cells injured by H(2)O(2) and a higher scavenging activity against free radicals. The relative effects of the lower molecular size, the presence of uronic acid, and the antioxidant activity of TIP2-1 appear to be significant. Accordingly, the Chinese truffle T. indicum might serve as an effective antioxidative healthcare food and source of natural antioxidants.

Abstract
Deficits in learning and memory accompanied by age-related neurodegenerative diseases are closely related to the impairment of synaptic plasticity. In this study, we investigated the role of thiol redox status in the modulation of the N-methyl-d-aspartate receptor (NMDAR)-dependent long-term potentiation (LTP) in CA1 areas of hippocampal slices. Our results demonstrated that the impaired LTP induced by aging could be reversed by acute administration of reductants that can regulate thiol redox status directly, such as dithiothreitol or β-mercaptoethanol, but not by classical anti-oxidants such as vitamin C or trolox. This repair was mediated by the recruitment of aging-related deficits in NMDAR function induced by these reductants and was mimicked by glutathione, which can restore the age-associated alterations in endogenous thiol redox status. Moreover, antioxidant prevented but failed to reverse H(2)O(2) -induced impairment of NMDAR-mediated synaptic plasticity. These results indicate that the restoring of thiol redox status may be a more effective strategy than the scavenging of oxidants in the treatment of pre-existing oxidative injury in learning and memory.

Abstract
Crude water-soluble polysaccharides (BRP) were extracted from the root of Brassica rapa L. using boiling-water. The polysaccharides were successively purified by chromatography on DEAE-cellulose and Sephadex G-100 column, giving three major polysaccharide fractions termed BRP1-1, BRP2-1, BRP3-1. The gel permeation chromatography (GPC) analysis showed that the average molecular weight (Mw) of polysaccharides (BRP1-1, BRP2-1, BRP3-1) were approximately 5.53×10(3) Da, 3.35×10(4) Da and 3.37×10(4) Da, respectively. Monosaccharide components analysis indicated that BRP1-1 was composed of arabinose and glucose in a molar ratio of 1.66:98.34. BRP2-1 was composed of arabinose, galactose and glucose in a molar ratio of 9.3:14.63:76.07. BRP3-1 was composed of arabinose, rhamnose, galactose and glucose in a molar ratio of 24.98:24.10:44.09:6.83. The evaluation of anti-hypoxia activity in vivo revealed that BRP is a novel potential anti-hypoxia agent.
