Comparison of volatile and non-volatile compounds as antioxidant indicators of water spinach (Ipomoea aquatic Forsk.)

Abstract The vertical distribution of early-stage juvenile sailfin catfish (Pterygoplichthys, Loricariidae), an invasive species, were investigated in littoral habitats and the center of channel with floating hydrophytes from the Red River system in Vietnam. Sailfin catfish were sampled from the upper water column with associated floating hydrophytes of the invasive water hyacinth (Eichhornia crassipes) and native water spinach (Ipomoea aquatic) and the bottom using hand nets (2-mm mesh sizes). Significantly higher numbers of early-stage juveniles were associated with floating hydrophytes compared to bottom sampling. The association between early stages of sailfin catfishes and floating hydrophytes, especially the free-floating invasive water hyacinth, supports the potential mechanism in the dispersal of an invasive fish.

Microbial immobilization is considered as a novel and environmentally friendly technology that uses microbes to reduce heavy metals accumulation in plants. To explore microbial resources which are useful in these applications, three water spinach rhizosphere soils polluted by different levels of heavy metals (heavy pollution (CQ), medium pollution (JZ), and relative clean (NF)) were collected. The community composition of heavy metal-immobilizing bacteria in rhizosphere soils and its effects on reducing the Cd2+ and Pb2+ concentrations in water spinach were evaluated. Four hundred strains were isolated from the CQ (belonging to 3 phyla and 14 genera), JZ (belonging to 4 phyla and 25 genera) and NF (belonged to 6 phyla and 34 genera) samples, respectively. In the CQ sample, 137 strains showed a strong ability to immobilize Cd2+ and Pb2+, giving Cd2+ and Pb2+ removal rates of greater than 80% in solution; Brevundimonas, Serratia, and Pseudoarthrobacter were the main genera. In total, 62 strains showed a strong ability to immobilize Cd2+ and Pb2+ in the JZ sample and Bacillus and Serratia were the main genera. A total of 22 strains showed a strong ability to immobilize Cd2+ and Pb2+ in the NF sample, and Bacillus was the main genus. Compared to the control, Enterobacter bugandensis CQ-7, Bacillus thuringensis CQ-33, and Klebsiella michiganensis CQ-169 significantly increased the dry weight (17.16–148%) of water spinach and reduced the contents of Cd2+ (59.78–72.41%) and Pb2+ (43.36–74.21%) in water spinach. Moreover, the soluble protein and Vc contents in the shoots of water spinach were also significantly increased (72.1–193%) in the presence of strains CQ-7, CQ-33 and CQ-169 compared to the control. In addition, the contents of Cd and Pb in the shoots of water spinach meet the standard for limit of Cd2+ and Pb2+ in vegetables in the presence of strains CQ-7, CQ-33 and CQ-169. Thus, the results provide strains as resources and a theoretical basis for the remediation of Cd- and Pb-contaminated farmlands for the safe production of vegetables.

Abstract The Babon River in East Semarang has been polluted by heavy metals sourced from industrial waste. So that water pollution at the Babon River estuary does not spread, it is necessary to carry out water treatment. This research uses a glass aquarium reactor and utilizes yellow velvetleaf (limmoncharis Flava) and water spinach (Ipomoea aquatic fork) plants as a medium to reduce the concentration of copper ions (Cu2+) by using variations in detention time. The results and analysis showed that yellow velvetleaf and water spinach could reduce the concentration of copper ions (Cu2+) in estuary surface water within 1 hour, 2 hours, 3 hours, and 5 hours. After going through several stages of a simple drinking water pre-treatment process, the results showed that yellow velvetleaf plants could reduce the concentration of copper ions (Cu2+) in Babon river water samples, from an initial concentration of 0.055 mg/L to 0.020 mg/L, with the highest efficiency percentage reduction up to 61.5%. As for water spinach, the concentration of copper ions that can be reduced only reaches the lowest level of 0.047 mg/L, with the highest percentage reduction efficiency of only 9.6% after the same pre-treatment process.

High Phosphate

Laundry waste contains high phosphate concentrations that exceeding levels in Regulation No. 82 of 2001 about Water Quality Management and Control of Water Pollution. When the waste is directly discharged into the sewers or river without treatment, it can cause water pollution and lead to eutrophication. Water spinach (Ipomoea aquatica Forsk) and Jeringau (Acorus Calamus l) might be use to absorb phosphate in laundry waste. The aim of this research is to investigate the efficiency of phosphate absorption by using water spinach and Jeringau. The experiments were carried out in a batch system. The results showed that the reduction efficiency of phosphate by Water spinach and Jeringau was 41.61% and 53.75%, respectively.

Abstract. Vegetables rich in vitamin K consumption could prevent bleeding and maintain bone status. The aims of the present work were to investigate i) the effect of household cooking (i.e., boiling for 5 min at 100 °C in distilled water and stir-frying for 3 min at 180 °C in hot canola oil) on phylloquinone bioaccessibility of five rich phylloquinone leafy vegetables, namely Water spinach (Ipomoea aquatic Forssk), Amaranth (Amaranthus blitum subsp. oleraceus L.), Chinese broccoli (Brassica alboglabra), Pak choi (Brassica rapa L.) and Drumstick (Moringa oleifera Lam.), and ii) the structural changes of these leaves before and after in vitro gastro-intestinal digestion. All the experiments were realized in triplicate for each vegetable. The amounts of phylloquinone in leafy vegetables were noticeable in almost all species and ranged from 94 to 182 μg/100 g DM. Their cell wall polysaccharide contents greatly varied from 4.3 to 8.4 g for 100 g. The content in bioaccessible phylloquinone was low in raw leaves (<25 μg/100 g DM) as well as its bioaccessibility (<15%). Leaf pectin content impaired phylloquinone bioaccessibility using principal component analysis. Boiling and stir-frying significantly improved the bioaccessibility of phylloquinone in leaves by a factor of three to twelve and two to seven respectively (p<0.05). These variations were associated with changes in leaf structure. Palisade and spongy cells appeared ruptured and disorganized after stir-frying. Given the estimated bioaccessibility of phylloquinones, the consumption of 500 g of cooked wet leaves per day would cover phylloquinone needs of an individual adult average body weight.
