Reports have indicated that lipid peroxidation is a key factor in soybean daddawa deterioration and Alliums are rich in antioxidants. The present study was carried out to investigate the preservative abilities of aqueous and ethanolic extracts of Onion (Allium cepa L) on stored soybean daddawa compared with Sodium Chloride treated samples. Soybean (Glycine max (L). Merr.) seeds fermented into soybean daddawa was preserved with both extracts (at 3, 5 and 7% concentration) and NaCl (at the concentrations of 0, 3 and 5%). The samples stored at 30±2°C for up to 14 days were analyzed for peroxide value (POV), free fatty acid (FFA), pH, titratable acidity (TTA), water absorption capacity (WAC) and fat absorption capacity (FAC). Type of solvent used in extraction did not have significant effect on all the storage indices. Extracts of Onion significantly lowered the POV, FFA and TTA generated in stored soybean daddawa. The pH of stored soybean daddawa samples treated with the NaCl and aqueous extract was not significantly affected while the ethanolic extract significantly reduced the pH from 8.26 – 8.34 to 5.72 – 5.89. The tested extracts lowered the WAC significantly while the FAC of treated soybean daddawa was not significantly affected compared to those treated with NaCl. Results of this study indicate that both extracts of Onion are more effective in lowering peroxidation in stored soybean daddawa and thus could be exploited for soybean daddawa preservation.

Uric acid is the final product of purine metabolism that will be excreted through urine, feces, and sweat. Excessive production of uric acid can cause hyperuricemia, known as gout. The skin of shallots (Allium cepa L.) is one of the household wastes that are very rarely used by the community. Ethanol extract of shallot skin (EESS) was tested for phytochemical screening and anti-hyperuricemia activity using potassium oxonate. Mice were divided into five groups (Allopurinol, Na-CMC, EESS 200 mg/kg BW, 300 mg/kg BW, and 400 mg/kg BW) and uric acid levels were observed at 2-hour intervals for six hours. Phytochemical screening shows that EESS has potential compounds in the treatment of gout. Tests to reduce uric acid levels showed that EESS has better potential than allopurinol at concentrations of 300 mg/kg BW and 400 mg/kg BW after six hours of induction in reducing uric acid levels.

Abstract Allium cepa L. is a commonly consumed vegetable that belongs to the Amaryllidaceae family and contains nutrients and antioxidants in ample amounts. In spite of the valuable food applications of onion bulb, its peel and outer fleshy layers are generally regarded as waste and exploration of their nutritional and therapeutic potential is still in progress with a very slow progression rate. The present study was designed with the purpose of doing a comparative analysis of the antioxidant potential of two parts of Allium cepa, i.g., bulb (edible part) and outer fleshy layers and dry peels (inedible part). Moreover, the inhibitory effect of the onion bulb and peel extracts on rat intestinal α-glucosidase and pancreatic α-amylase of porcine was also evaluated. The antioxidant potential of onion peel and bulb extracts were evaluated using 2,2-diphenyl- 1-picryl hydrazyl (DPPH), ferric-reducing antioxidant power assay (FRAP), 2,2’-azino-bis- 3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging assay, H2O2 radical scavenging activity and Fe2+ chelating activity. Total flavonoids and phenolic content of ethanolic extract of onion peel were significantly greater as compared to that of onion bulb. Ethanolic extract of onion peel also presented better antioxidant and free-radical scavenging activity as compared to the ethanolic extract of bulb, while the aqueous extract of bulb presented weakest antioxidative potential. Onion peel extract’s α-glucosidase inhibition potential was also correlated with their phenolic and flavonoid contents. The current findings presented onion peel as a possible source of antioxidative agents and phenolic compounds that might be beneficial against development of various common chronic diseases that might have an association with oxidative stress. Besides, outer dry layers and fleshy peels of onion exhibited higher phenolic content and antioxidant activities, compared to the inner bulb. The information obtained by the present study can be useful in promoting the use of vegetable parts other than the edible mesocarp for several future food applications, rather than these being wasted.

ONION YIELDS UNDER DIFFERENT IRRIGATION MANAGEMENTS     2 ABSTRACT   The present work aimed at evaluating the agronomic performance of onion under irrigation, submitted to three methods of irrigation management. The experiment was conducted in the experimental field of DTCS / UNEB, in Juazeiro, from June to November 2013. A randomized block design was used with three treatments and seven replicates. The treatments considered were: Tensiometry, Penman-Monteith FAO and Class A pan. The cultivar used was Vale Ouro IPA-11. The following characteristics were evaluated: total productivity, commercial productivity, production of bulbs class 1, 2, 3 and 4, average diameter, average bulb weight, bulb dry matter content, titratable acidity, soluble solids, soluble solids / titratable acidity ratio and pungency. Irrigation management methods based on soil moisture content and microclimate, yields above the national average. The Class A pan method and tensiometry did not differ statistically from the standard Penman-Monteith-FAO method, so the choice of method should be based on the availability of tools as well as the cost of implantation and operation.   Keywords: Allium cepa L., evapotranspiration, tensiometry, water management.

The effect of an ethanolic extract from callus of <em>Catharanthus roseus</em> on <em>Allium cepa</em> root cells divisions was investigated. Two lines: white and green callus, were established on solid B5 medium with IAA 1 mg/l and kinetin 0.1 mg/l. The HPLC analysis of callus extracts showed the presence of indole alkaloids, however not known pharmacologically active alkaloids or derivatives used in semisynthesis (vinblastine, ajmalicine, serpentine, yohimbine, vindoline and catharanthine) have been found. The ethanolic extract of <em>C. roseus</em> callus inhibited the number of mitoses in <em>Allium cepa</em> root tip cells. Short (1-3 hours) treatment resulted in an increase in the index of late prophases, with characteristic light spaces, and the index of metaphases with twisted chromosomes forming an equatorial plate or irregular structures of c-metaphases. At the same time, the percentage of anaphases and telophases decreased significantly. Longer treatment of the root tip inhibited mitotic activity, stopping it completely already after 12 hours. Interphase nuclei became at first denser and homogeneous, eventually their structure became , partitioned into zones and formation of chromatin territories, with distinct large nucleoli has been observed. Electron microscope observations revealed well developed rough endoplasmic reticulum and thick, invaginating cell membrane.

Aim: This study evaluated the physicochemical, functional and pasting properties of garri fortified with soybean flour. Methodology: Soybean flour was incorporated into the garri prior to garrification at a ratio of 10, 20, 30, 40 and 50% for samples A, B, C, D and E respectively. Sample without soybean flour served as control. Standard analytical procedure was used in the evaluation of all six samples. Results: The pH and titratable acidity (TTA) of the samples varied respectively, from 4.59 - 6.48 and 0.08 - 0.17 % lactic acid. There was significant (P<0.05) decrease in pH with increase in soybean flour, while the reverse was the case for TTA. Swelling power, bulk density and water absorption capacity of the soybean fortified garri ranged from 8.74 - 17.81%, 0.60 - 0.80 g/ml and 13.44 – 19.43 % respectively. Control sample (100% garri) had hydrogen cyanide (HCN) content of 1.50 mg HCN/100g while samples with soybean flour had no detectable levels. Peak viscosity, trough, breakdown, final viscosity and setback varied significantly (P<0.05) from 101.19 - 399.44, 90.92 - 320.19, 10.28 - 79.25, 123.19 - 451.50 and 32.28 - 131.31 RVU respectively. Peak time and pasting temperatures ranged from 5.18 – 6.34 min and 74.28 – 92.88 oC. Conclusion: The study revealed that a good quality garri can be produced with the incorporation of soybean flour up to 50%, the garri is safe for consumption as there was no HCN detected, and the decrease in viscosity provides for a soft textured, mouldable garri that is convenient for swallow.

Abstract Fundamental research has extensively described the various biological and medical effects of consuming the microalgae spirulina or its constituents. A number of studies indicate an increase in the immune response when they are used for the manifestation of anti-inflammatory, antidiabetic and other important properties. The composition of spirulina and its biological effects make it a unique dietary supplement, the inclusion of which in food products will provide them with functional properties. It has been proven that spirulina has a number of important functional and technological properties for its use as a component in recipes for meat products. In the study of the functional and technological properties of spirulina, it was found that the water absorption capacity was 117.8%, fat absorption was 117.0% and the swelling degree was 177.6%. At the same time, spirulina had low emulsifying and gelling properties. The introduction of spirulina paste into the recipe in a dosage of 1 to 2.5% can increase the quality indicators of the finished product. Results of organoleptic and physicochemical indicators, the most optimal level of spirulina administration was established, which was 2%. Analysis of the results of changes in the peroxide value in the pate samples during storage showed the presence of a high antioxidant activity of spirulina, which will extend the shelf life of the finished product.

Terminalia actinophylla (Mart), commonly known as "chapada", is used in folk medicine for the treatment of diarrhea, diabetes and anti-inflammatory. However, studies on its toxicity are still incipient. The present work was carried out with the objective of evaluating the phytochemical profile and the cytogenotoxic effect of the ethanolic extract of the T. actinophylla bark using the Allium cepa L. seed. Seeds of A. cepa were subjected to different extract concentrations (1.25, 2.5, 5 and 10 mg/mL), a negative control (NC - distilled water) as well as trifluralin (PC - positive control), during 24 h of exposure. The phytochemical profile of the extract was obtained to identify the main secondary metabolites. The cytotoxicity (mitotic index) and the genotoxicity (chromosomal alterations) were analyzed by means of the collection of 5,000 meristematic cells. The statistical analysis was carried out using the Kruskal-Wallis test (p<0.05). The phytochemicals present in the extract were tannins, saponins and reducing sugars. Only the lowest concentration (1.25 mg/ml) of T. actinophylla was cytotoxic in comparison with NC. There was a significant increase in the total average of chromosomal changes to lower concentrations (1.25 and 2.5 mg/ml) compared to NC. Probably, phytochemicals in the extract interfere with the cell cycle and cause DNA damage in A. cepa in lower concentrations. However, if bad studies must be carried out on mammals, since the extract with medicinal purpose can have harmful effects on the organism.
