The nutraceutical properties of Aloe vera have been attributed to a glucomannan known as acemannan. Recently information has been published about the presence of fructans in Aloe vera but there are no publications about acemannan and fructans as prebiotic compounds. This study investigated in vitro the prebiotic properties of these polysaccharides. Our results demonstrated that fructans from Aloe vera induced bacterial growth better than inulin (commercial FOS). Acemannan stimulated bacterial growth less than fructans, and as much as commercial FOS. Using qPCR to study the bacterial population of human feces fermented in a bioreactor simulating colon conditions, we found that fructans induce an increase in the population of Bifidobacterium spp. Fructans produced greater amounts of short chain fatty acids (SCFA), while the branched-chain fatty acids (BCFA) did not increase with these polysaccharides. Acemannan increased significantly acetate concentrations. Therefore, both Aloe vera polysaccharides have prebiotic potentials.

Chemotherapeutic drugs commonly induce peripheral neuropathic pain, which limit their clinic use. In the present study, the effect of fucoidan on the development of vincristine‑induced neuropathic pain was evaluated and the underlying mechanism was examined. A neuropathy model was established in Sprague‑Dawley rats by intraperitoneal injection of vincristine sulfate 50 µg/kg once a day for 10 consecutive days. Fucoidan (50, 100 or 200 mg/kg.) and pregabalin (10 mg/kg) were injected for 14 consecutive days. Behavioral assessments were then performed and the expression of GABAB receptor was determined. The results showed that a single treatment with fucoidan did not prevent the induction of vincristine‑induced mechanical or cold allodynia. However, repeated fucoidan administration attenuated vincristine‑induced mechanical and cold allodynia in a dose‑dependent manner. Additionally, the analgesic effects of fucoidan contributed to an upregulation in the expression of GABAB receptor in the spinal cord. Furthermore, all the effects of fucoidan against vincristine‑induced neuropathy were reversed by saclofen, a selective GABAB receptor antagonist. These results suggested that the antinociceptive effects of fucoidan may be through activation of GABAB receptor, and fucoidan may be a promising drug for the treatment of chemotherapeutic drug-induced neuropathic pain.

In spite of their potential as biologically active compounds, the high molecular mass and viscous natures of fucoidans have hampered their applications especially as a therapeutic agent. Herein the fucoidan-degrading enzyme activities were partially purified from the cultured cells of Sphingomonas paucimobilis PF-1 mainly by ammonium sulfate precipitation. This enzyme preparation degraded fucoidans from the Korean Undaria pinnatifida sporophyll into several low-molecular weight fuco-oligosaccharides (LMFOs) with less than 3,749 Da. The FTIR spectra of intact fucoidan and mixture of LMFOs (1,389∼3,749 Da) showed no significant structural difference except for about 10% reduced level of sulfate esters in LMFOs. The LMFOs have exerted strong anticoagulating activities at which the activated partial thromboplastin time (APTT) and thrombin time (TT) were significantly prolonged, although 3∼20 times weaker activities were observed than those of intact fucoidan. In addition, unlike intact fucoidan, LMFOs did not affect significantly to the prothrombin time (PT). These results suggest that the partially purified fucoidan-degrading enzyme preparation is valuable for the production of fuco-oligosaccharides having anticoagulating activities, and that the molecular weight and/or sulfate content of the fucoidan from the Korean Undaria pinnatifida sporophyll could be important factors for its anticoagulating activity.

Aloe vera (L.) Webb. Natural Sources of Antioxidants – A Review SpringerLink
Many studies have proved that bioactive components of Aloe vera have an anti-inflammatory effect and support lipid and carbohydrate metabolism, helping to maintain normal sugar and cholesterol levels in blood and normal body weight. When aloe is applied externally, it accelerates the regeneration of the damaged skin. Aloe contains antioxidants, which may increase the shelf-life and nutritional value of food; therefore, it is widely used in cosmetic, pharmaceutical and food industry. An antioxidant activity was shown for leaf’s skin, flowers and gel of aloe. In this work the future of A. vera as effective antioxidants is primarily discussed and expected trends are summarised. Furthermore, the bioactive components and the health-promoting effects of A. vera are investigated.

Objective: The protective effect of aloe vera is due to its anti-inflammatory properties. This experimental study focused on revealing the effects of aloe vera on antioxidant systems and determining the number of degenerated neurons after cerebral ischemia and reperfusion. Methods: Twenty-one rats were divided equally into three groups: group I rats were used as controls; group II rats were fed with standard diet, and group III rats were fed with standard diet plus aloe vera for 30 days. For groups II and III, the right middle cerebral arteries were occluded for 45 min and then reperfused for 24 h. After these procedures, rats in all groups were sacrificed. The levels of malondialdehyde and nuclear respiratory factor-1 and superoxide dismutase activity in the right cerebral cortex were measured. The number of degenerated neurons was counted in histological samples of the right cerebral cortex. Neuronal nitric oxide synthase expression was examined with immunohistochemical methods. Results: Superoxide dismutase activity and nuclear respiratory factor-1 levels were decreased in group II compared with group I (p

Fucoidan is a series of sulfated polysaccharides derived from brown algae, and have reported to have various biological activities. Previously, we demonstrated that fucoidan derived from Cladosiphon okamuranus and Undaria pinnatifida effectively augmented anti-tumor immunity in combination with Agaricus blazei mycelia extract. In this study, we evaluated the capacity of the fucoidan-agaricus mix (FAM) to enhance oral mucosal immune function. Fifteen healthy volunteers (mean age, 41.2 years old; range, 22–56 years old; 8 males, 7 females) ingested 4 capsules each containing 250 mg FAM powder every day for 12 weeks. As a result, the mean of secretory rates of salivary secretory immunoglobulin A (sIgA) tended to be increased by the FAM administration for 4 and 12 weeks as compared with the initial value. The enhanced salivary sIgA secretion was more distinctly observed in subject group whose initial values of salivary sIgA secretory rate were lower than the total average. Furthermore, the intake of FAM led to significant augmentation in the salivary sIgA secretion (by 1.3-fold) in the group of subjects under 40 years of age. On the other hand, concanavalin A-induced blastogenic response of peripheral blood mononuclear cells and serum IgA concentration was not elevated during this trial. Therefore, it was suggested that FAM stimulated functional maturation rather than expansion of B lymphocyte. The intake of FAM did not significantly affect NK cell activities. In addition, the safety of FAM consumption was confirmed because no abnormal findings were observed in general clinical tests. From the results, it was suggested that intake of FAM was useful in augmentation of oral mucosal immune defense via enhancing salivary sIgA production.
