Phytochemicals and antioxidant properties of red sweet pepper cv Topepo grown in soil amended with different organic fertilizers were compared with that grown in unamended soil. Organic fertilizers are an environmentally friendly alternative to recovery infertile soils that resulted from the intensified agricultural practices in red Topepo production. The aim was to discriminate the effects of organic fertilizers one from each other on the quality of red Topepo to find out the better sustainable fertilization practice for its cultivation. Results showed that compost from vegetable residues (CV) enhanced the synthesis of total phenols, flavonoids, ascorbic acid, vitamin E, carotenoids, anthocyanins, as well as carbohydrates, antioxidant activities, and aroma profiling, compared to horse manure (HD), compost from olive pomace (CO), and control (CTR). The results indicated a specificity between the quality of red Topepo and compost composition, highlighting that vegetable residues increased the synthesis of secondary metabolites, enhancing sustainably, the nutraceutical, sensorial, and economic value of red Topepo. The fertilizer composition resulted largely responsible for the synthesis of bioactive compounds, flavor, and aroma of this fruit.

Background: Young ricegrass (Oryza sativa L.) can be introduced as one of functional food product since sprouts have been much interested in this era due to their high nutritive values. Bio-fortification of selenium is one strategy to enhance plant bioactivity. However, the level of selenium used is varied among species of plants, hence, the proper level needs to be explored.Objective: To investigate the influence of selenium bio-fortification on nutritional compositions, bioactive compounds content and anti-oxidative properties of young ricegrass.Methods: Sodium selenite ranging 0, 10, 20, 30 and 40 mg Se/L has been hydroponically bio-fortified into ricegrass then grown for 8 d and investigated the changes of growth characteristics, selenium content, accumulation of bioactive compounds and anti-oxidative properties.Results:  Results revealed that selenium bio-fortified exogenously increased the accumulation of selenium in ricegrass by 529% at 40 mg Se/L treatment without negatively changes in leaves biomass at the day of harvesting. However, root part weight slightly decreased when increased selenium level. Selenium at concentration of 10 and 20 mg Se/L can stimulate the production of phenolic compounds and antioxidant activities in young ricegrass as measured by DPPH, ABTS, FRAP and chelating assay. Conversely, higher level of selenium fortification reduced the accumulation of phenolics in ricegrass may due to pro-oxidant expression.Conclusion: Selenium bio-fortification can be used as a useful technique to improve quality of ricegrass plantation. 10 mg Se/L treatment was an ideal to trigger the synthesis of phenolics which exhibited high antioxidant activities. While, 40 mg Se/L treatment was ultimate for the production of Se plant foods.Keywords: Antioxidant activities; Bio-fortification; Ricegrass; Selenium

Abstract Goji berry tea, a traditional herbal tea, is the main ate mode of goji berry in Asia, yet few studies in comparison with red goji berry tea and black goji berry tea are carried out. This study investigated the effects of water temperature and soak time on the colour, phytochemicals, and the antioxidant capacity [2,2-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 2,2-diphenyl-1-picrylhydrazyl radical (DPPH), and the ferric-reducing antioxidant power (FRAP)] of two goji berry tea. A comparison of the bioactive compounds and antioxidant activities between black and red goji berry tea was conducted. Results showed that both red and black goji berry tea were rich in phytochemicals, giving high antioxidant ability. The levels of bioactive compounds and the antioxidant activity of the two goji berry tea increased as the increases in soak temperature and time. Black goji berry tea had higher phytochemicals and antioxidant property than those of red goji berry tea. Infused at 100° water for the same time, the levels of total polysaccharides (150 mg/100 ml), total polyphenols (238 mg/ml), and antioxidant capacity (550 μmol/100 ml) of black goji berry tea were 3.5, 2, and 5 times higher, respectively, in comparison with red goji berry tea. The results of this study demonstrate that hot drink of goji berry in China is a good habit and black goji berry tea may be a better choice.

Chili plants are one of the horticultural commodities that have economic value and are widely planted in Sungai Geringging Village, Kampar Kiri District, Kampar Regency. The main obstacle in achieving the quantity and quality of chili production is the attack of pests and diseases. This service aims to provide knowledge to chili farmers in Sungai Geringging Village about the types of pest and disease that attack chilies, symptoms of attack, and methods of control. The extension methods are lectures, questions and answers, discussions, demonstrations and practices with regard to chili plants. Extension is in the form of indoor presentation using LCD and in-focus tools by demonstrating the types of pest and disease that attack chilies and their attack symptoms, discussion and question and answer about pests and diseases of chili plants and their control techniques. Service programs in the form of counseling and demonstrations have been very well responded by chili farmers, counseling and demonstrations with material on how to introduce and control chili pests have never been received, plus in the cultivation of chili plants the obstacles that are often faced by farmers are problems with pests and diseases therefore participating farmers pay closer attention.

Background: Microorganisms from understudied habitats have been shown to be an important source of novel bioactive compounds. Endophytes constitute an underexplored group of microorganisms, of which those from aquatic plants have been even less studied. Nelumbo nucifera (lotus) is an aquatic plant with medicinal properties. A screening program for endophytes from N. nucifera by our research group resulted in many microbial isolates, of which isolate L-003 was a promising candidate, exhibiting antimicrobial and antioxidant activities. Objectives: The major objectives were to characterize the endophyte L-003 for its antimicrobial and antioxidant properties, identify the constituent bioactive compounds by GC-MS and characterize their activities further using in silico software. Methods: L-003 was identified by PIBWin software. Antimicrobial activity of the aqueous and organic extracts of culture supernatant of L-003 was checked against a panel of bacteria and fungi. Since the ethyl acetate extract showed the best antimicrobial activity, it was further characterized by thin layer chromatography, an activity confirmed by bioautography and purified by column chromatography. Total antioxidant capacity was assayed by standard techniques. Partially purified metabolite fingerprints were identified by GC-MS analysis. Results: Based on morphological and biochemical analyses, isolate L-003 was identified as belonging to Streptococcus sp. All the organic solvent extracts showed antimicrobial activity. Ethyl acetate extract showed maximum antimicrobial activity against all selected targets and exhibited antioxidant activity too, though butanol and aqueous extracts showed higher antioxidant activity. Two compounds, Acetic acid,-hydroxy, methyl ester and Disulfide, dipropyl, were identified by GC-MS in the metabolite fingerprint. These compounds showed differences in observed and calculated retention indices and could, therefore, be novel. In silico activity, characterization confirmed the antimicrobial and antioxidant properties attributed to these compounds. Conclusion: This is the first study reporting metabolite fingerprinting, identification and characterization of bioactive compounds from an endophytic isolate of Nelumbo nucifera. We conclude that endophytes from aquatic plants could be prospective sources of bioactive compounds, in this case with antimicrobial and antioxidant activities.

Abstract The aim of the experiment was to determine the changes in the contents of bioactive compounds and antioxidant/antiradical activity in fresh-cut fruits of sweet pepper cv. ‘Blondy F1’ and ‘Yecla F1’, depending on the postharvest treatment. Treatment with hot water and short-term storage decreased the content of bioactive compounds and antioxidant/antiradical activity of fruit peppers. The treatment with water at 55 °C for 12 sec. of fresh-cut fruits caused lower losses in content of bioactive compounds and antioxidant/antiradical activities than the treatment with water at 45 °C for 10 min. There was a significant correlation between the content of total polyphenols and antioxidant and antiradical activity of pepper fruits depending on the cultivar and the experimental season.

Swiss chard (Beta vulgaris L. var. cicla) is a popular vegetable because it is nutritious, robust, easy to grow. It requires regular applications of nitrogen, which causes accumulation of oxalates and nitrates within the plant. Oxalates and nitrates are known health hazards but the use of organic fertilizers have been shown to reduce their accumulation and to promote accumulation of beneficial phytochemicals. We therefore determined the effect vermicompost (VC), Tithonia diversifolia green manure (Tithonia) and urea on the quality of Swiss chard. The experiment was laid out in a Randomised Complete Block Design (RCBD) replicated three times with thirteen treatments. Leaf nutrient elements, TSS, polyohenols, Vitamin C and antioxidants were determined using standard procedures. Treatment effects were significant only for aluminum, phosphorus and calcium. The values were highest on VC 50 kg N ha-1 and Urea 50 kg N ha-1, Tithonia 50 kg N ha-1 + Urea 50 kg N ha-1, and VC 50 kg N ha-1, and VC 100 kg N ha-1 for aluminum, phosphorus and calcium, respectively. Lowest response was reported on Tithonia 50 kg N ha-1, control and Tithonia 50 kg N ha-1 + Urea 50 kg N ha-1 for aluminum, phosphorus and calcium, respectively. The treatments significantly influenced the percentage of polyphenols, vitamin C and the antioxidant capacity while no significance was reported for total soluble solutes. The polyphenols and vitamin C content were highest on Tithonia 100 kg N ha-1 and control, respectively. Low polyphenol and vitamin C contents were recorded on VC 50 kg N ha-1 and VC 100 kg N ha-1, respectively. A similar trend was observed for antioxidant activity since a positive correlation was observed between the polyphenols and vitamin C and the antioxidant activity. Tithonia green manure improves Swiss chard quality.
