This study investigated the nutraceutical potential of ripe and unripe plantain fruit peels which are commonly discarded as food wastes. Proximate and mineral analyses of the samples were performed as per the standard methods of the Association of Official Analytical Chemists. Preliminary phytochemical screening of aqueous, acetone and methanol extracts of the peels was also carried out in accordance to standard methods. From the results of the study, acetone extract of the unripe peel showed the presence of eight phytochemicals while its ripe peel showed the presence of four. Aqueous and ethanol extracts of both peels showed the presence of same phytochemicals i.e., terpenoids, cardiac glycosides, phenols, flavonoids, alkaloids, reducing sugars and saponins. Meanwhile, tannins was absent in all three solvent extracts of both peels. Fat, ash, crude fibre and carbohydrate contents of the unripe peel were higher than those of the ripe. However, moisture and protein contents of the ripe peel were significantly higher (P < 0.05) than those of the unripe. Of all the nine essential minerals assayed (K, Na, Mg, Ca, P, Fe, Zn, Mn, Cu), concentrations of all except calcium were significantly higher (P < 0.05) in the unripe peel than those of the ripe peel. Notably, none of the heavy metals (Co, Cr, Cd, Pb, Ni) assayed was detected in both samples. This study concludes that ripe and unripe plantain fruit peels could serve as promising sources of nutrients and bioactive compounds essential for the health of both livestock and humans.

<p>Shilajit (asphaltum)  is produced  by the long term humification  of dead plant material  and organic vegetable matter  by different micro-organisms and has great potential for the treatment of a variety of human conditions.  This treatise reviews its origin, sources, chemical composition, biological  and  commercial importance. Phytochemical analysis was done by standard methods to evaluate  different Shilajit (asphaltum) classes of compounds in different samples of shilajit  which are responsible for their  biological activity.  Shilajit`s anti-microbial activity has been evaluated  against four different bacterial strains viz., <em>Escherichia coli, Psuedomonas aeuroginosa</em>, <em>Klebisella pneumonia</em> and <em>Staphylococcus aureus. </em>Phytochemical analysis illustrated  that shilajit contains  terpenoids, cardiac glycosides, saponins and reducing sugars. Surprisingly,  some classes of compounds are absent in shilajit  viz., alkaloids, flavonoids, tannins and anthraquinones. . Shilajit showed no response towards halophytic bacteria and  negligible activity was shown towards other strains of bacteria. Since   anti-microbial activity is based on environmental factors  its activity varied  between locations.</p>

The proximate and phytochemical screening of Senna occidentalis were carried out to assess some nutrients and phytobiotic properties of the leaves. The fresh leaves were thoroughly rinsed, sparsely spread on jute mat and dried at room temperature for 6 – 7 days until they became crispy, thereafter they were milled and subjected to proximate and phytochemical analyses. Data showed that the leaves had low moisture (9.35 9.35%), high crude protein (21.88 21.88%), crude fibre, crude fat, ash and nitrogen free extract (NFE) , of 19.72, 16.88, 9.70 and 22.47% respectively. The phytochemicals positively present were cardiac glycosides, phenols, flavols, flavonols and alkaloids, while saponnins were largely present. From the results, Senna occidentalis leaf meal can be a potential source of vegetable protein and some vital mineral elements as supplements to poultry feeds. Besides, the high levels of antioxidants and antimicrobial agents present in the sample which are known to promote growth by enhancing nutrient utilization, repair of worn out tissues and disease control could make Senna occidentalis leaves worthy of being a phytobiotic additive in poultry diets.

The aim of this study was to investigate the phytochemicals present in fermented castor seed (ogiri Igbo). 1kg of castor seed was dehulled and cleaned after which seeds were wrapped in banana leaves and boiled for 6-8 h. The boiled seeds which were still wrapped in the leaves were left to ferment for 4-6 days. Later, the seeds were mixed with ash from oil palm bunch and ground into paste. Subsequently, the condiment (ogiri Igbo) formed was wrapped in leaves in small portions.Phytochemical and GC-MS analysis were performed on the condiment using standard methods. Phytochemicals investigated were tannins, saponins, flavonoids, steroids, terpenoids, cardiac glycosides, phlobactannins, phenols, proteins, reducing sugars and anthraquinones. While steroids, reducing sugars and anthraquinones were absent in the condiment, flavonoids, phlobactannins, and alkaloids were present in abundance (++), the least abundant being the terpenoids, cardiac glycosides and phenols (+) and the most abundant phytochemicals reportedly present in the condiment were saponins and proteins. GC-MS analysis performed on the fermented castor seed (ogiri Igbo) showed that forty eight compounds were present in the said condiment and while the most abundant compound reported was 9,12-Octadecadienoic acid (Z,Z)-methyl ester (17.43%), the least abundant was 2-t-Butyl-3,6-dimethyl pyrazine (0.35%). In conclusion, although some of the relevant phytochemicals may have been lost to fermentation, the condiment still retains some health aiding phytoconstituents in appreciable amounts.
