Abstract Background: Beetroot juice has been demonstrated to decrease blood pressure due to the high inorganic nitrate content, but few studies have tested the effect of other high nitrate vegetable juices on blood pressure. Methods: This pilot randomized crossover trial aimed to investigate the effect of two different high nitrate vegetable juices on plasma nitrate concentrations and blood pressure in healthy adults. Eighteen healthy volunteers were randomized to receive 115 ml of beetroot juice or 250 ml of green leafy vegetable juice for seven days. Blood samples were collected, and clinic blood pressure measured at baseline and at the end of each juice consumption. Daily home blood pressure assessment was conducted two hours after juice consumption. Nitrate and nitrite concentrations were analysed using a commercially available kit on a Triturus automated ELISA analyser. Hills and Armitage analysis was used for the two- period crossover design and paired sample t- tests were performed to compare within-group changes. Results: Plasma nitrate and nitrite concentration significantly increased and there was significant reduction in clinic and home SBP mean during the beetroot juice period (P-values 0.004 and 0.002, respectively). Home DBP reduced significantly during green leafy vegetable juice consumption week (P-value 0.03). The difference between groups did not reach statistical significance during the formal crossover analysis adjusted for period effects. Conclusion: Beetroot juice and green leafy vegetable juice may reduce systolic or diastolic blood pressure but there was no statistically significant difference between the two juices, although this was only a pilot study.

Hormetic Effect

Corchorus olitorius, a leafy vegetable with high nutrient content, is normally collected from the wild, in areas that are prone to cadmium (Cd) toxicity. However, studies on how Cd accumulation affects vegetative and reproductive traits of leafy vegetables in South Africa are limited. Therefore, this study tested the effect of Cd accumulation on C. olitorius morphological traits. Plants were grown under various Cd concentrations and studied for variation in vegetative and reproductive traits as well as accumulation in roots and shoots. Plants exposed to 5 mg/kg Cd had longer roots with higher moisture content, heavier fresh and dried stems, as well as dried leaves, which indicated a hormetic effect in C. olitorius after exposure to low Cd concentration in the soil. Again, plants treated with 5–10 mg/kg Cd, accumulated toxic (>10 mg/kg dry weight) Cd within shoots and roots, with minor morphological alterations. Plants could survive, with some morphological defects, Cd toxicity up to 20 mg/kg in soil. Only plants exposed to 5 mg/kg could reproduce. Cd accumulation increased with an increase in the soil, with higher accumulation in shoots. The translocation factor was high (>1) in all Cd concentrations. In conclusion, C. olitorius can accumulate toxic Cd, and yet grow and reproduce either normally or better than the control. The proposed dose of Cd that induces hormesis in C. olitorius is 5 mg/kg in the soil. Therefore, C. olitorius is suitable for phytoremediation of Cd contaminated soils, but unsafe for consumption when it grows in such areas.

The effects of different seed treatment methods and durations of exposure on germination of wild okra (Corchorus olitorius), a traditional leafy vegetable consumed in many parts of Africa, were investigated. Seeds were exposed to seven treatments (hot water at 80 °C, hot water at 100 °C, dry heat at 80 °C, dry heat at 100 °C, concentrated sulphuric acid, 10% hydrogen peroxide and water at room temperature) for periods of up to 30 minutes. Exposure for five to 15 minutes in hot water at 80 °C was the most effective treatment for enhancing germination (>90%), followed by five minutes in hot water at 100 °C (80%) and 30 minutes in sulphuric acid (57%). Other treatments were less effective. Soaking seeds in hot water at approximately 80 °C for about 10 minutes can be recommended, therefore, to farmers as a simple, cheap and very effective way of germinating wild okra.

Katuk leaf (Sauropus Androgynus) is a kind of green leafy vegetable which has many benefits for the community, one of which is to treat heartburn, fever, earache, and yaws. Vitamins contained in Sauropus Androgynus and are useful for the body, one of which is vitamin C. Vitamin C has properties that are easily damaged against heat, and easily dissolve in water. This study aims to look at vitamin C levels in fresh, steamed and boiled Sauropus Androgynus by the UV-Vis Spectrophotometry method. Determination of vitamin C levels with this method is relatively inexpensive and good in accuracy. The results obtained with 30 samples with an average level of vitamin C in fresh Sauropus Androgynus 0.0036%, Sauropus Androgynus steamed 0, and Sauropus Androgynus boiled 0.0032%. It can be concluded that the vitamin C levels of boiled Sauropus Androgynus do not decrease significantly, compared to the levels of Vitamin C on freshSauropus Androgynus. the result is different from the Sauropus Androgynus that are steamed vitamin C levels become zero mg
