Abstract
OBJECTIVE Mitragyna speciosa Korth is traditionally used in Thailand. They have a high level of antioxidant capacities and bioactive compounds, the potential to modulate rumen fermentation and decrease methane production. The aim of the study was to investigate the different levels of microencapsulated-Mitragyna leaves extracts (MMLE) supplementation on nutrient degradability, rumen ecology, microbial dynamics, and methane production in an in vitro study. METHODS A completely randomized design was used to assign the experimental treatments, MMLE was supplemented at 0%, 4%, 6%, and 8% of the total dry matter (DM) substrate. RESULTS The addition of MMLE significantly increased in vitro dry matter degradability both at 12, 24, and 48 h, while ammonia-nitrogen (NH3-N) concentration was improved with MMLE supplementation. The MMLE had the greatest propionate and total volatile fatty acid production when added with 6% of total DM substrate, while decreased the methane production (12, 24, and 48 h). Furthermore, the microbial population of cellulolytic bacteria and Butyrivibrio fibrisolvens were increased, whilst Methanobacteriales was decreased with MMLE feeding. CONCLUSION The results indicated that MMLE could be a potential alternative plant-based bioactive compound supplement to be used as ruminant feed additives.

Abstract
Fungi play an important role in the solution to important global problems. Making use of processes and goods that are based on fungi can help promote sustainability by making the most efficient use of natural resources. Fungi stand apart from other organisms due to their extraordinary capacity to generate organic compounds. They are necessary for the psychological and physiological well-being of people worldwide. They are excellent producers of vitamins, pigments, hydrolytic enzymes, biofuels, organic acids, polysaccharides, and secondary metabolites such as antibiotics, anticancer treatments, hypocholesterolemic pharmaceuticals, and immunosuppressants. Other secondary metabolites include biofuels. In addition, polysaccharides are produced by them. We provide a condensed explanation of the significance of secondary metabolites in a variety of industries, such as the pharmaceutical industry, the food industry, the textile industry, and the transportation industry. In addition to providing a better understanding of biosynthetic regulation and the possibilities of genetic engineering, improved laboratory processes for the selection of nontoxigenic fungal strains have permitted the manufacture of larger quantities of safe commercial items. The significance of fungi in industrial settings is the topic that will be investigated in this review.

Abstract
Chemical studies on Acanthaster planci have afforded two steroids, 5α-cholesta-24-en-3β,20β-diol-23-one (1) and 5α-cholesta-9(11)-en-3β, 20β-diol (2). Structures compounds 1 and 2 were determined with the help of spectroscopic studies. Compound 1 showed strong antibacterial activity (21.0 ± 0.06 mm) against P. aeruginosa. Compounds 1 and 2 were also active against human breast carcinoma cells (MCF-7) with LC50 values of 49 ± 1.6 and 57.5 ± 1.5 μg/ml, respectively. This bioactivity was comparable to the currently used anticancer agent, cisplatin (LC50 46 ± 1.1 µg/ml). Compounds 1 and 2 exhibited anti-α-glucosidase activity with IC50 values of 58 ± 0.8 and 55 ± 0.5 µg/ml, respectively, whereas IC50 of Acarbose as a positive control was found to be 36 ± 0.4 µg/ml in our bioassay.

Abstract
BACKGROUND Cyanobacteria have a worldwide distribution in the terrestrial habitats, occurring predominantly on the surface of the soils, stones, rocks, and trees, practically in moist, neutral or alkaline aeries. The unique natural and bioactive compounds from cyanobacteria with various biological activities and an extensive range of chemical classes have a significant capability for expansion of the pharmaceuticals and other biomedical purposes. OBJECTIVES Regardless of the progresses in our knowledge on cyanobacteria, however, cyanobacteria are still viewed as an unexplored source of potential drugs. In this study presence of bioactive compounds among the cyanobacteria culture collection of Iran, where a wide variety of strains can be found, was investigated. MATERIAL AND METHODS We explored one Nostoc strain isolated from rice fields in Golestan province of northern Iran for searching for novel products. The chemical construction of the new bioactive compound was clarified by application of liquid chromatography-mass spectrometer (LC-MS) and Marfey's analysis of the degradation products. RESULTS We found a novel peptide aldehyde compound from a hydrophilic extract of the Nostoc sp. Bahar_M, which is composed of the three subunits, 2-hydroxy-4-(4-hydroxyphenyl) butanoic acid (Hhpba), L-Ile, and L-argininal. According to the structural information, we predicted that the novel peptide-aldehyde compound probably to be trypsin inhibitors. CONCLUSIONS Results demonstrated that terrestrial cyanobacteria are a promissing resource of bioactive natural products.

Abstract
Nanotechnology is a new subject of interest in the field of food industry. Therefore, scientific and technological studies have been intensified in the last 10 years because of the promising results associated with the potential application of functional properties in food products, such as physical and chemical stability, protection and controlled release of bioactive compounds, and facilitated solubility of lipophilic compounds. Lipids have been used as raw material for the preparation of nanostructures, mainly owing to the solubilization capacity of lipophilic bioactive compounds, as well as because of the advantage of potentially using natural ingredients for production on an industrial scale. Thus, in this review, we describe the information reported in scientific literature on the chemical, physical, and structural properties of lipids used in the preparation of solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs). We reviewed the production methods; structural lipid components; emulsifying systems; bioactive lipophilic compounds; and the physical, thermal, and oxidative properties of SLN and NLC. In addition, important methods for characterizing these systems with regard to particle size, polydispersity index, zeta potential, morphology, crystallization behavior, and polymorphism are discussed with examples, in order to support studies that consider physical stability during processing and storage. Furthermore, studies on the applications of SLNs and NLCs in foods are only found for model systems, justifying the compilation of a series of studies on the potential applications to encourage future works. In addition, we have described the aspects still under discussion, related to the possible risks and regulatory aspects of nanotechnology in food.

Abstract
Monguba fruit has a seed with a chestnut-like flavor that can be consumed boiled, fried, and roasted. These nutritious seeds also have been used in popular medicine to treat several diseases. Nevertheless, the nutritional and functional potential of monguba seed is still underexploited. In this sense, we investigated the nutritional and functional components of monguba seeds. These seeds showed high total content of sugars, mainly sucrose, whereas the content of the raffinose family oligosaccharides was low. The mineral assay showed high amount of minerals, namely potassium, calcium, magnesium and zinc, which indicate that monguba seeds can be a new source of these minerals. UHPLC-ESI-MS/MS analysis showed caffeic, ferulic and 4-hydroxybenzoic acids as the main phenolic compounds, mainly in the esterified form, in these seeds. Monguba seed showed high lipid content, in which the main compounds were palmitic acid and γ-tocopherol. The soluble and insoluble phenolic fractions from monguba seeds showed high antioxidant activity measured by the oxygen radical absorption capacity (ORAC) and the trolox equivalent antioxidant capacity (TEAC) assays. Therefore, the monguba seeds have great potential to be explored by food, pharmaceutical and cosmetic industries due to their chemical composition.

Abstract
Objective The aim of this study was to evaluate the effect of dietary incorporation of tannin-rich woody species on meat oxidative stability, carcass traits and meat quality in goats. Methods Two tannin-rich species were tested using a three-treatments feeding trial, where treatments consisted of: Larrea divaricata and Acacia aroma both at 12.5% in dry matter basis of the diet and a control diet (alfalfa hay). All feeding diets were iso-protein and iso-energy. Carcass conformation, carcass compactness, carcass fatness and subcutaneous fat deposition were evaluated. Intake, liveweigh, Longissimus thoracis et lumborum muscles of goats were analyzed in order to evaluate quality parameters such as pH value, instrumental color evaluation, water holding capacity, total phenolic content, antioxidant activity, meat oxidative stability and fatty acid profiles in meat. Results Feed intake, liveweight gain, carcass and meat traits did not differ among treatments. Changes in meat lipid profile among treatments were observed for oleic and elaidic acid contents. Meat total phenolic content and antioxidant activity did not differ among treatments; although, meat oxidative status after storage at room temperature, as well as under refrigerated and frozen conditions were different between control and both supplemented groups. Conclusion The inclusion of Acacia aroma and Larrea divaricata leaves in goat diet enhanced meat oxidative stability. Modulation of the ruminal biohydrogenation of fatty acids produced by condensed tannins of these plant species need to be further investigated.

Abstract
Medicinal plants have played a major role as a functional food and pharmacological source of active substances. Barley grass (BG) is young green barley leaves. It is the young grass of the common barley plant Hordeum vulgare L. of the family Poeaceae (Graminae). It is a type of green grasses, and the only vegetation on the earth that can supply sole nutritional support from birth to old age. It contains a wide spectrum of vitamins, minerals, as well as eight essential amino acids that we must get from our diets. BG possesses several pharmacological activities as anticancer activity, anti-oxidant activity and anti-inflammatory activity. It has been argued that BG helps blood flow, digestion and general detoxification of the body. The major pharmacologic interest of BG is its use in the treatment of chronic diseases. The beneficial effects observed in chronic disease may be related to bioactive compounds contained in BG such as superoxide dismutase (SOD) and bioflavonoids (lutonarin and saponarin). Thus, this paper is focused on the various studies that emphasize the therapeutic potential of BG in the prevention and treatment of chronic diseases.

Abstract
OBJECTIVE To evaluate the in vitro activity and synergism of the combinations of natural honey and curcuma starch against Rhodotorula mucilaginosa in correlation with total phenolic, flavonoid contents, and diastase activity. METHODS The Folin-Ciocalteu test was used to determine the total polyphenols content and the flavonoid content was analyzed using by the aluminum chloride method. The antifungal activity of the natural honey, determined by an agar well diffusion assay and agar incorporation method. RESULTS Total phenolic content varied from (63.930.11) to (95.366.08) mg GAE/100 g honey as gallic acid equivalent. Total flavonoids content varied from (5.41±0.04) to (9.94±0.54) mg CE/100 g. Diastase activity values were between (7.3±2.8) and (26±2.8). The zone inhibition diameter for the six honey samples without starch ranged between 6 and 20 mm. When starch was mixed with honey and then added to well, a zone inhibition increase diameter 7 and 21 mm. The percentage increase was noticed with each variety and it ranged between 5% and 62.5%. The minimal inhibitory concentrations for the six varieties of honey without starch against Rhodotorula mucilaginosa ranged between 28% and 36% (v/v). When starch was incubated with honey and then added to media, a minimal inhibitory concentration drop has been noticed with each variety. It ranged between 6.66 % and 20% (w/v). No significant correlation was established between diastase activity and bioactive compounds. CONCLUSIONS The mixture of curcuma starch and honey could lead to the development of new combination antibiotics against Rhodotorula infections.
