“…These findings concur with those obtained by Aristimunha et al (2016) and Ogbe and Affiku (2012) . Proportionately, the amounts determined from different plant parts in this study (see Table 2 ) compare well with those reported in other studies evaluating D. edulis phytochemical composition ( Ogboru, 2015 ; Ebana et al, 2016 ; Okolo et al, 2016 ; Oyetunji and Opeyemi, 2017 ). These compounds have been noted to possess bactericidal, virucidal, fungicidal, and antiparasitical properties which can be exploited in pharmaceutical medicine or animal feed additives.…”

“…The African Safou plant which is scientifically known as D. edulis plant has attracted the attention of the researchers in Africa due to its traditional use in treating many human ailments as described by Ebana et al (2016) and its avalability in many West African countries ( Nwokonkwo, 2014 ). There exists little information on the plant use in managing animal diseases and correcting nutritional deficiencies in Africa and its use in treating human ailments ( Ebana et al, 2016 ) and its reported nutritional characteristics ( Vidanarachchi et al, 2005 ) informed its choice in this study. Determination of product efficacy and safety is the first step in considering its use in animal feed or human food chain ( Okolo et al, 2016 ).…”

“…Phytochemical screening of the D. edulis fruit, seed, stem bark, resin, and leaves has tested positive for alkaloids, tannins, saponins, cyanogen glycosides, flavonoids, and phytates ( Yelwa et al, 2017 ). Besides, the plant’s extracts and secondary metabolites have been found to exhibit some antimicrobial, antioxidant, anti-sickle-cell disease properties (drepanocytes) in treatment of parasitic skin diseases, cough, malaria, mouth infections, tonsillitis and eradication of jiggers ( Ebana et al, 2016 , 2017 ). Studies by Valenzuela-Grijalva et al (2017) showed that the D. edulis seed, leave, stem, and bark also showed antimicrobial properties when used in vitro against resistant strain of Staphylococcus aureus .…”

“…Further, findings from a study by Oyetunji and Opeyemi (2017) indicate that various parts of the D. edulis have broad spectrum antibacterial activity. Decoctions from different parts of the plant are used to relieve certain digestive disorders caused by microbial infection ( Ebana et al, 2016 ). The D. edulis fruit has traditionally been consumed (boiled or roasted) due to its nutritional and medicinal properties ( Kadji et al, 2016 ), while the seeds, which are usually discarded, are known to contain high amounts of soluble carbohydrates and lipids ( Bratte, 2010 ).…”

This study aimed at testing the efficacy and safety of Dacryodes edulis plant parts in diets fed to chicken. The plant has potential for use as a natural prebiotic to substitute the conventionally used antibiotic growth promoters in poultry production. Phytochemical analyses of the plant leaves, stem, and bark combination (stembark) and seed powders from the D. edulis were carried out. The powder from the three D. edulis plant parts were used as supplement in formulating six experimental diets tested in this study. The diets were TL0Ed (0.5% leaves powder), TL1Ed (1.0% leaves powder), TB0Ed (0.5% stembark powder), TB1Ed (1.0% stembark powder), TS0Ed (0.5% seeds powder), and TS1Ed (1.0% seeds powder). Besides, a positive (T+ positive control; 0.5-g oxytetracycline as recommended by the manufacturer) and a negative (T- negative control; having no commercial antibiotic and no plant supplement) diets were prepared for comparison purposes. The diets were fed to a total of 288 dual-purpose chicken for a period of 14 weeks. The chicken growth and body composition characteristics, blood chemistry, and microbiota count were collected and used as indicators of the plant parts efficacy and safety. The analysis of the D. edulis plant parts significantly differed (P ≤ 0.05) in their phytochemical contents. The initial body weight and feed conversion efficiency ratios were not significantly different (P ≥ 0.05) between and among treatment groups. However, significant differences (P ≤ 0.05) were detected in the feed intake and body weight gain at eighth week. Live weight at eighth week was significantly different (P ≤ 0.05) with its values ranging between 503.32 and 614.93 g for treatments TL1Ed and TNeg-, respectively. The dietary treatment of D. edulis leaves, stembark, and seed powder at the two inclusion levels significantly (P ≤ 0.05) decreased the colonies forming unit of Escherichia coli and Salmonella sp. as compared with negative control treatment in the eighth week phase. The level of glucose, total cholesterol, triglycerides, aspartate aminotransferase, alanine amino transferase, alkaline phosphatase, and the packed cell volume did not differ significantly (P ≥ 0.05) between and among dietary D. edulis treatments. The findings from this research provide crucial information on the efficacy and safety of D. edulis plant parts. This is an important step in testing the potential of the plant in use as a prebiotic in chicken feeds production.

The Potential Application of Nanoparticles on Grains during Storage: Part 1 – An Overview of Inhibition against Fungi and Mycotoxin Biosynthesis

Mycotoxins and Food Safety

Cereals and legumes are the major staples across the globe, thus providing nutrition to humans, and their by-products utilized as animal feeds. However, mycotoxins synthesized by fungi contaminate these grains on the field during cultivation and are transferred to the storage centers. These fungi infect and deteriorate stored grains, thereby tampering with food security. Moreover, the deterioration decreases nutrient content and alters the physicochemical properties of grains. The current conventional methods used to reduce grain contamination are becoming ineffecitive, coupled with the detrimental health effects it has on the consumer and to the environment. Herein, we present an overview of the use of nanoparticles (NPs) as an alternative and novel method of reducing mycotoxin biosynthesis due to their potent biocidal properties. Silver nanoparticles (AgNPs) are considered and have shown promising and effective fungicidal properties against important storage fungi, and pests hence could be utilized in the agriculture and food sector for a vast myriad of applications. These may help to either minimize/eradicate the exposure to the mycotoxins and its adverse health effects, hence contributing to the holistic growth and development of people.

Garcinia kola belongs to the Garcinia genus of the Clusiaceae family and Malpighiales order. It contains more than 180 members all over the globe. It is found all over Asia and in tropical African countries. In Africa, traditionally, G kola is used to manage and treat cancer, diabetes, malaria, analgesics, hypertension, and other numerous ailments. This review aimed to comprehensively update relevant information regarding the pharmacological potential of Garcinia kola. Electronic databases such as ScienceDirect, PubMed, Wiley, Google Scholar, Hindawi, and Springer extracted valuable information from original scientific research papers. Inclusion Criteria. Antioxidant, antimicrobial, antidiabetic, antibacterial, medications, antiviral, traditional medicine, ethnopharmacology, toxicity, cytotoxic action, chemical composition, mineral elements, GCMS analysis, and any other related phrases were used as filters to find studies. Exclusion Criteria. Data from questionable online sources, as well as thesis reports and review publications, were excluded from this investigation. The investigation revealed that seeds of G. kola are very efficient as antioxidant, antimicrobial, antidiabetic, antihypertension, antianalgesic, and anti-inflammatory. The study also found that too much consumption of the seeds caused low fertility and toxicity. However, the safety and efficacy of G. kola have not been wholly assessed in humans, and further well-designed clinical trials are needed to corroborate preclinical findings. The mechanism of action of the seed extract should be examined. The standard dose and safety of the seed should be established.
