Opis:
This research was conducted to assess various bioactive compounds in the meat of mudskippers found in the Sungsang 2 Village, Banyuasin regency, South Sumatra. The research had been synthesized using n-hexane from February to May 2018 at Agricultural Technology Production Laboratory, Sriwijaya University. Subsequently, the mudskippers (Periopthalmus chrysospilos, Boleopthalmus boddarti, and Periophthalmodon schlosseri) extract was synthesized and further investigate by conducting the GC-MS analysis. The study of bioactive compounds in mudskippers was carried out by evaporating in vacuum evaporation at 30°C. The results showed that Periopthalmus chrysospilos has five classes of bioactive compounds such as steroids, terpenoids, carotenoids, canabinoids, and alkaloids and Boleopthalmus boddarti has five classes of bioactive compounds including steroids, carotenoids, terpenoids, bufadienolides, and carotatoxins. Furthermore, Boleopthalmus dussumieri has four classes of bioactive compounds such as steroids, carotenoids, terpenoids, and carotatoxins and Periophthalmodon schlosseri has three classes of bioactive compounds including steroids, carotenoids and terpenoids. This research discussed the potential benefit of all bioactive compounds in mudskippers for alleviating and treating children with enuresis through the review of literature on the most cited bioactive compounds.

Opis:
Petals of edible flowers (EF) are rich in biologically active compounds with many proven benefits for human health. However, studies on the effects of EF in humans after consumption are lacking. This pilot explorative study evaluated the changes in urinary phenolic excretion in healthy volunteers to whom different doses of phenolics from edible roses (Gourmet Roses™) have been added to a meal. Rose petals were picked fresh once a week for three weeks, showing significantly increasing values of total phenolic content, total anthocyanin content, and antioxidant activity (measured as ferric reducing antioxidant power (FRAP) and as DPPH• and ABTS•+ scavenging activities) from the first to the third week. After the meal, direct associations between urinary phenolics and both the EF phenolic content and the antioxidant activity were found in a multiple regression model. These new insights on EF consumption, to be confirmed by larger trials, suggest that the urinary phenolic excretion of healthy volunteers increases with increasing rose phenolic content.

Drought conditions may have direct or indirect effects on plant physiology, biochemistry, and molecular characteristics. The purpose of this study was to investigate the effects of drought stress on the physiological, biochemical, and molecular responses of three different watermelon cultivars with varying levels of drought tolerance (24: drought resistant, CS: moderately tolerant, and 98: drought sensitive). The cultivars exhibited different responses to cope with water stress according to their tolerance level. Drought induced significant reductions in chlorophyll a, total chlorophyll and carotenoid content and glutation reductase and ascorbate peroxidase activity in the sensitive cultivar unlike in the moderately tolerant and drought resistant cultivars. Additionally, the expression levels of NAC1, NAC2, ORE1, WRKY24, SAG12, SAG13, KCS2, CER1, DREB2A, LTP3, SWEET15, and PYL9 genes were measured using qRT-PCR. The expression ratios of the genes significantly varied depending on the gene location and on the tolerance of the cultivars. Results showed that the physiology and biochemical and molecular pathways of tolerant cultivars change to adapt to drought conditions. Therefore, the drought-resistant cultivar copes with drought stress by increasing proline content and antioxidant enzyme activities, as well as by increasing the expression of specific genes.

Opis:
The major purpose of the present study was to determine the chemical composition of dried Gomphrena celosioides Mart., including crude protein, lipid, total sugar, reducing sugar, ash, crude fiber, moisture, crude pectin, and total saponins in particular. This plant contains a large percentage of total saponins, which are widely used in food technology and pharmaceutical industries. In our study, the conditions for the extraction of total saponins from the plant were optimized, with special focus on cellulase concentration, pH, hydrolyzation time, and temperature. The highest amount of total saponins content (TSC) was 1.550±0.016% under optimal extraction conditions (cellulase concentration: 0.7% (v/w), hydrolyzation time: 4 h, hydrolyzation temperature: 60EC, and pH value: 5). Accordingly, the total saponins from G. celosioides Mart. were easily extracted.

Opis:
Inonotus obliquus is a parasite on the birch and other trees and is also a well-known medicinal mushroom. Its sterile conk is highly sought for its bioactive compounds such as phenols, polysaccharides, triterpenoids, and steroids. It was traditionally used to treat various gastrointestinal diseases, viral and parasitic infections, to counteract the progression of cancers, and to stimulate the immune system. We used acute gamma irradiation, followed by short-term submerged cultivation, as an oxidative stress inducer to enhance the synthesis of mycelial metabolites. The 300 Gy and 400 Gy doses showed the best results across the whole experimental design. Each assayed criterion had a different corresponding optimal stimulation dose. In one experiment, sublethal doses of irradiation triggered the dry weight of the cultured mycelium to increase by 19.764%. The free radical scavenging potential of the mycelium extracts increased by 79.83%. The total phenolic content of mycelium extracts and culture broth increased by 55.7% and 62.987%, respectively. The total flavonoid and sinapinic acid content of the broth increased by 934.678% and 590.395%, respectively. As such, gamma irradiation pretreatment of the mycelial inoculum proved an interesting, economically and environmentally effective tool for stimulating secondary metabolite synthesis in submerged mycelium cultures.

Opis:
Obesity is a global health problem associated with many comorbidities such as type 2 diabetes and cancer. The number of individuals with overweight and obesity have increased dramatically within the past few years. Given the worldwide cost of an obesity pandemic, it is crucial to understand molecular pathways and identify novel factors that regulate fat storage in humans. In recent years, Caenorhabditis elegans has been widely used to investigate metabolic and neuroendocrine mechanisms involved in the regulation of energy metabolism. In this review, we describe similarities in fundamental signalling pathways regulating fat accumulation between nematodes and mammals. Like in humans, fat storage in C. elegans depends on the interaction of genetic and environmental factors such as diet, microbiota and ambient temperature. Despite many challenges, the simplicity of use, relatively short lifespan, genetic conservation and availability of many valuable experimental techniques make C. elegans an attractive and useful model organism in obesity research.

Opis:
Due to the increasing microbial tolerance to commonly used food preservatives, as well as growing consumer awareness of their adverse impact on human health, alternative methods of pathogens reduction in food are widely investigated. The aim of this research was to examine the antimicrobial activity of red raspberry pomace and seed preparations against enterohemorrhagic Escherichia coli (EHEC), Salmonella Typhimurium, Salmonella Enteritidis, Listeria monocytogenes, and probiotic Lactobacillus rhamnosus strain. The combined action of LAB (lactic acid bacteria) and raspberry preparations on the pathogenic species was also evaluated. The results of our study showed no or weak antibacterial effect of raspberry preparations on the pathogenic bacteria tested. Regardless of preparation concentration (1.0 or 2.0 mg/mL), the bacteria number after 48-h incubation was usually higher than in the culture at the initial stage and varied from 105 to 107 cfu/mL. On the other hand, probiotic Lactobacillus rhamnosus strain caused a significant reduction in the enteric pathogen count after 24-h co-culture with LAB. The concentrations of both Salmonella serotypes were below the detection limit of the analytical methods applied. Moreover, the combined use of LAB and raspberry preparations resulted in the total elimination of Salmonella strains and the reduction in L. monocytogenes number from 105 to 102 -104 cfu/mL after 24-h co-culture. EHEC revealed the highest resistance to the mixed culture effect. The synergic antimicrobial effect suggests the possibility of applying probiotic bacteria and berry preparations as natural antimicrobial agents in the food industry.

Opis:
In the current study, it was hypothesized that the addition of strawberry polyphenol-rich fractions to a high-fructose diet mitigates disorders in liver functions, lipid metabolism, and in the antioxidant and pro-inflammatory status of rats. Therefore, a fraction rich in ellagitannins and proanthocyanidins (EP), and a fraction containing compounds of both mentioned classes of polyphenols and additionally anthocyanins (EPA), in doses of 0.28 and 0.70 g/100 g, respectively, were added to a standard or a high-fructose diet administered to rats for six weeks. The EPA fraction was more beneficial in alleviating the consequences of consuming excess fructose in the diet than the EP fraction. Probably, that fraction containing considerable amounts of carbohydrates was more extensively metabolized by intestinal bacteria, which resulted in higher levels of cecal short chain fatty acids (SCFAs) as well as cecal and urinal ellagitannin metabolites. As a further consequence, diet supplementation with the EPA fraction caused more favorable changes in the levels of serum interleukin 6 and serum antioxidant capacity of water-soluble substances (ACW), in atherogenicity index lg((triglyceride/high-density lipoprotein cholesterol), hepatic oxidized glutathione as well as reduced to oxidized glutathione ratio). Efforts should be made to develop strawberry polyphenol-rich preparations containing the preferred anthocyanins, which is, however, difficult due to the instability of this class of phenolic compounds during the technological process.

Opis:
This review summarises the research on phenolic compounds in apples in relation to their geographical origin, cultivars, technological processes, and human health effects due to their antioxidant activity and bioavailability. Apples are popular among consumers and are known as a rich source of vitamins, minerals, and biologically active compounds. In this review article, we have focused on their phenolic compounds. Some epidemiological studies have confirmed the protective effects of apples against chronic diseases, which can be linked to the high content of phenolics in plant tissues and their bioavailability. However, according to the available literature, the geographical origin and variety of apples influence the content of these bioactive compounds and are highly related to their antioxidant activity fluctuation. The gathered studies have confirmed that the choice of polyphenol-rich raw material as well as proper processing are important to achieve high-quality fruit-based products with a high content of antioxidants after a few stages of production. It was proven that the processing of apples could significantly modify the content of phenolics in the finished products, including juices, concentrates, vinegars, and ciders. For instance, the use of high pressure or vacuum has been proposed as a highly potent solution in inhibiting flavonoid degradation during intensive processing. Moreover, several methods have been screened to monitor the phenolic content and antioxidant activity of apple samples, based on spectrophotometry, HPLC, LC-MS, and LC-MS/MS techniques for chemical compound separation and identification. The main assumptions of these techniques and results obtained are described in this review.

Opis:
This comparative study aimed to evaluate the effects of different drying methods such as solar drying, shade drying (SHD), freeze drying (FD), oven drying, and microwave drying on the physicochemical properties, bioactive components, and antioxidant activity of Centella asiatica. The results showed that out of all the treated samples, FD-treated samples showed the lowest moisture content (2.4%), the lowest water activity (0.24%), and the highest rehydration ratio (5.51%). For samples treated using different drying methods, significant differences in Commission on Illumination – LAB (L *, a *, and b *) values and total color difference (E) were observed. FD-treated samples showed the minimum color change (E) and highest lightness (L*). Additionally, upon Fourier transform infrared spectral analysis, no major changes in the functional groups were observed between C. asiatica leaves processed using different drying methods. FD-treated samples showed the highest antioxidant activity followed by SHD-treated samples, as measured by 2,2-diphenyl-1-picrylhydrazyl and 2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid radical scavenging assays. The phenolic (chlorogenic acid, rutin, kaempferol, and quercetin) and triterpene saponin (madecassoside, asiaticoside, madecassic acid, and asiatic acid) contents of the dried samples of C. asiatica were measured using high-performance liquid chromatography, which showed that the FD method allowed for the highest retention of phenolic and triterpene saponins among the tested drying techniques. The physicochemical characteristics, antioxidant potential, and bioactive retention of the samples that underwent FD treatment were superior to those of other methods, and therefore, FD can be employed as the first-line drying technique for processing C. asiatica leaves.

Diet is a major environmental factor which maintains metabolic balance and body homeostasis. The aim of the study was to present the latest reports on the biological activity of the food compounds in a critical review. It has been shown that bioactive substances supplied with food e.g. polyphenols, flavonoids or phenolic acids exhibit immunomodulatory and anti-inflammatory fun-ctions. What is more, they favourably downregulate major oncogenes and enhance suppressors’ expression. Studies show that these substances can be an important component of cancer prevention and treatment. However, there are micronutrients like iron or copper which elevated levels in cancer cells occurs and should be considered as a therapeutic targets.
