Background: B. abyssinica is a succulent member of the genus Bulbine (Asphodelaceae). It occurs from the Eastern Cape, through Swaziland and further north to Ethiopia. The species is used in traditional medicine to treat rheumatism, dysentery, bilharzia, cracked lips and diabetes. The tea leaf is used to treat cough, vaginal and bladder problems. Whereas B. abyssinica has ethno medicinal value, not much data concerning its phytonutrient, macro and micro element composition can be found in literature. Materials and Methods: Therefore, the present study was undertaken to determine the nutritional quantitative composition of the plant using standard procedures. Results: The proximate analysis revealed the carbohydrate, crude fibre, moisture, ash, crude protein and crude fat contents as 74.8%, 8.9%, 8.8%, 8%, 7.7% and 0.6%, respectively. The species showed high levels of oxalates and phytic acids, moderate levels of alkaloids, flavonoids, saponins and phenols, while tannins were in low levels. Vitamin A, C and E contents were 12, 12.3 and 22.1 mg/100g, respectively. Amongst the mineral elements investigated, potassium and calcium were in high levels. Magnesium, iron, sodium, aluminium and phosphorus were moderately present, while manganese, zinc and copper where in low amounts. These vitamins and mineral elements were within their recommended daily allowance in humans. Conclusion: The amount of these phytochemicals suggests the plant can serve as nutritional supplements which are vital in maintaining good health status. These findings also suggest the potential role of B. abyssinica in the treatment of infections and some chronic diseases, especially diabetes mellitus.

Aim: Citrullus lanatus is a fruit widely consumed for its pulp though incompletely, as its other parts (seed and rind) are discarded and may possibly offer bioactive compounds involved in ameliorating certain disease conditions. Hence, this study aimed at comparatively investigating the nutritional composition and antioxidant properties of the seed, pulp and rind of C. lanatus so as to inform the inclusion of these different parts into the fare of the people. Methodology: Standard analytical methods of Association of Official Analytical Chemists were used to determine proximate, phytochemical, vitamin, mineral and antioxidant aspects of the fruit parts. The results were analyzed using Student’s t-test at .05. Results: The proximate analysis showed a high moisture value in the pulp (93.34 +/- .82) followed by the rind (77.11 +/- 3.44) and the seed (10.00 +/- .48). High crude protein and fiber contents were both noted in the seed followed by the rind and pulp. Mineral determinations revealed potassium to be abundant in the rind (452.31mg/kg) than the seed (305.7mg/kg) and the pulp (100.5mg/kg), followed by calcium occurring more in the rind (292.61mg/kg) than in the pulp (257.21mg/kg) and seed (227.45mg/kg) and then manganese being the least concentrated among the minerals. The investigated phytochemical principles revealed the highest concentration of cardiac glycosides in the seed (14.82 +/- .66) than the rind (1.95 +/- 0.80) and pulp (1.10 +/- 0.17), followed by saponins occurring most in the rind (12.05 +/- 3.91) than the seed (10.17 +/- 0.63) and pulp (.13 +/- .01). The seed had the highest DPPH scavenging activity followed by the rind and pulp respectively. The seed also showed a higher reducing power and lipid peroxidation capacities than the other fruit parts suggesting a potent property for antioxidant activity in the fruit parts of C. lanatus. Conclusion: The findings imply that both seed and rind of C. lanatus can be good sources of nutritional, phytochemical and antioxidant components in addition to the pulp which is commonly consumed and these may be implicated in management of certain diseases with further evidential research.

Phytochemicals possessing the antioxidant properties naturally present in food attract a greater interest to healthcare researchers due to their desirable health effects on human health as they can be explored for protection against oxidative deterioration. Macrtotyloma uniflorum is a leguminous plant belonging to the family Fabaceae and commonly known as Horse gram. Aqueous and ethanol extracts of seeds of Macrotyloma uniflorum were evaluated for their anti-inflammatory effects using the scientific protocol on experimental rats. Extraction was carried out using the cold maceration method, and the anti-inflammatory activity was evaluated using a digital plethysmometer in the experimental rats injected with carrageenan to produce paw edema. Preliminary phytochemical studies confirmed the presence of various bioactive compounds such as alkaloids, glycosides, carbohydrates, proteins and amino acids, terpenoids, tannins, and phenolic compounds in both extracts while flavonoids were found only in ethanol extract. Both extracts of M. uniflorum seeds (200 mg/ml) significantly (p<0.01) reduced the paw edema volume induced by carrageenan. The ethanol extract of M. uniflorum seeds exhibited more potent anti-inflammatory activity than water extract, that might be due to the presence of flavonoids in ethanol extract. The activity of the extracts was compared with diclofenac sodium (10mg/kg b.wt.) as a reference drug. From the results, it may be suggested that the antioxidative potential of phenolic constituents and flavonoids is the primary factors for the anti-inflammatory activity of M. uniflorum seeds extracts.

Nutritional Profile

This study investigated the chemical and nutritional profile and antioxidative properties of cultivated Coprinus comatus . Proximate analysis revealed that C. comatus is rich in carbohydrates, dietary fibres and proteins, and could also be a valuable source of phenolics. Additionally, fat content is low, consisting mainly of polyunsaturated and omega-3 fatty acids. Furthermore, the safety profile of C. comatus is satisfactory, with all elements of toxicological importance within the proposed limits. Oral treatment with C. comatus for 42 days improved the antioxidant capabilities and ameliorated carbon tetrachloride-induced liver damage in rats, marked by decreased serum aminotransferase levels and lipid peroxidation intensity. Glutathione concentrations increased in a dose-dependent manner. Histological morphometric and immunohistochemical analysis confirmed antioxidative and hepatoprotective potential. These findings imply that cultivated C. comatus could be considered a nutraceutical, having beneficial nutrient and therapeutic properties.

Herbs derived from Taraxacum genus have been used as traditional medicines and food supplements in China for hundreds of years. Taraxacum mongolicum is a famous traditional Chinese medicine derived from Taraxacum genus for the treatment of inflammatory disorders and viral infectious diseases. In the present study, the bioactive phenolic chemical profiles and antioxidant activities of flowers, leaves, and roots of Taraxacum mongolicum were investigated. Firstly, a high performance liquid chromatography method combined with segmental monitoring strategy was employed to simultaneously determine six bioactive phenolic compounds in Taraxacum mongolicum samples. Moreover, multivariate statistical analysis, including hierarchical clustering analysis, principal component analysis, and partial least squares discriminant analysis were performed to compare and discriminate different parts of Taraxacum mongolicum based on the quantitative data. The results showed that three phenolic compounds, caftaric acid, caffeic acid, and luteolin, could be regarded as chemical markers for the differences of flowers, leaves, and roots of Taraxacum mongolicum. In parallel, total phenolic contents, total flavonoid contents and antioxidant activities of different parts of Taraxacum mongolicum were also evaluated and compared. It is clear that Taraxacum mongolicum had antioxidant properties, and the antioxidant capacities of different parts of Taraxacum mongolicum in three antioxidant assays showed a similar tendency: Flowers ≈ leaves > roots, which revealed a positive relationship with their total phenolic and flavonoid contents. Furthermore, to find the potential antioxidant components of Taraxacum mongolicum, the latent relationships of the six bioactive phenolic compounds and antioxidant activities of Taraxacum mongolicum were investigated by Pearson correlation analysis. The results indicated caftaric acid and caffeic acid could be the potential antioxidant ingredients of Taraxacum mongolicum. The present work may facilitate better understanding of differences of bioactive phenolic constituents and antioxidant activities of different parts of Taraxacum mongolicum and provide useful information for utilization of this herbal medicine.

Spinach Leaves

The present study was designed to document the nutritional and functional properties of Ceylon Spinach, Mustard as well as Pumpkin leaves. These samples were selected owing to their economic affordability and utilization within the local population. Proximate analysis revealed a significant percentage of minerals, proteins, carbohydrates and vitamin C in all the leaf extracts. Phytochemical screening displayed Ceylon Spinach, Pumpkin and Mustard leaves to be rich sources of polyphenols (106.6, 76.24 and 89.86 mg/100 g) and alkaloids (12.8 %, 13.2 % and 16.8 %) respectively. Furthermore, these edible leaves could effectively scavenge 2, 2-diphenyl-1-picryl-hydrazyl (DPPH) and hydrogen peroxide (H2O2) free radicals with Mustard leaves showing the greatest efficiency, hence portraying antioxidant properties. Ceylon Spinach leaves depicted the highest reducing power compared to the other samples. Additionally, the edible leaf extracts were shown to possess anti-bacterial abilities with Mustard leaves displaying the strongest inhibition against growth of both Gram positive (ZOI 18.5mm) and negative bacteria (ZOI 25.5mm). Interestingly, the selected samples could also elevate the growth of probiotic Lactobacillus acidophilus in vitro thereby confirming their prebiotic potential. Therefore, inclusion of these edible leaves in the diet may promote good health owing to their nutritional and therapeutic benefits.

Main Components

Substances inhibiting or preventing oxidative damage in the target molecule are called antioxidants. It has been shown that antioxidants are substances that contribute to the prevention of a number of serious human diseases, and antioxidant activity is one of the important parameters for the quality of food products and ingredients. Phenolic compounds are of greatest importance for this review. It is now established that whole grain cereals contain a large number of bound polyphenols. It is known that cereals have high nutritional value, contain unsaturated fatty acids, basic mineral elements, proteins and β-glucans, and are also characterized by the presence of various chemical substances with antioxidant properties. In recent years, work has begun in some Western countries to study the content of antioxidants in various grains. In Russia, only a small amount of work has been devoted to the study of these important chemical compounds in grain crops. It should be noted that, although these species are considered to be one of the main components of human nutrition, research in the field of determining their antioxidant activity has not been sufficiently carried out. In order to attract the attention of plant growers, plant breeders, plant physiologists, geneticists and biotechnologists, we offer a review of current literature.

Abstract This study aimed to investigate the proximate and phytochemicals present in seeds of 24 mung bean (Vigna radiate L.) genotypes from four provinces of China for estimating their nutritional and antioxidant properties. Proximate analysis of mung bean genotypes revealed that starch, protein, fat, ash and water-soluble polysaccharide ranged from 39.54–60.66, 17.36–24.89, 4.24–12.18, 2.78–3.53 and 1.99–2.96 g/100 g respectively. The five principal fatty acids detected in mung beans were stearic acid, palmitic acid, linoleic acid, oleic acid, and linolenic acid. The contents of insoluble-bound phenolic compounds, soluble phenolic compounds, and flavonoids ranged from 0.78 to 1.5 mg GAE g− 1, 1.78 to 4.10 mg GAE g− 1, and 1.25 to 3.52 mg RE g− 1, respectively. The black seed coat mung bean genotype M13 (Suheilv 1) exhibited highest flavonoid and phenolic contents which showed strong antioxidant activity. Two flavonoids (vitexin and isovitexin) and four phenolic acids (caffeic, syringic acid, p-coumaric, and ferulic acids) were identified by HPLC. Vitexin and isovitexin were the major phenolic compounds in all mung bean genotypes. The content of soluble phenolic compounds had positive correlation with DPPH (r2 = 0.713) and ABTS (r2 = 0.665) radical scavenging activities. Principal component analysis indicated that the first two principal components could reflect most details on mung bean with a cumulative contribution rate of 66.1%. Twenty-four mung bean genotypes were classified into four groups based on their phenolic compounds contents and antioxidant activities. The present study highlights the importance of these mung bean genotypes as a source of nature antioxidant ingredient for the development of functional foods or a source of health promoting food.
