Acanthus montanus (Nees) T. Anders belongs to the family Acanthaceae and is one of the most threatened and underutilized species of vegetables in Africa. However the leaves of this plant are part of a consortium infusion (agabada nkwu) given to post-natal mothers within and around Mbaise in Imo State, South Eastern Nigeria, to ensure health and vitality of both nursing mother and child. The proximate, phytochemical and selected mineral contents of the Acanthus montanus leaf were investigated to ascertain the various components. The fresh plant sample was obtained from Ife, Ezinihitte Mbaise Local Government Area of Imo state, Nigeria. The sample was air-dried at room temperature for 72 hours prior to the various analyses, which were done using standard methods. The results of the phytochemical analysis showed 1.60 % flavonoids, 6.67 % tannins, 5.60  % alkaloids, 6.45 % saponins, 0.26 % phytate, 5.41% oxalate, 0.49 % phenol and 0.019 % Hydrogen Cyanide (HCN). The percentage proximate evaluation for moisture content, carbohydrate, protein, fibre, ash content and fat were: 11.85, 37.86, 17.72, 16.70, 10.56 and 5.31 respectively, while the percentage quantities of selected minerals; iron, magnesium, potassium, calcium, phosphorus, sodium, manganese, zinc and copper were: 0.014, 0.569, 3.152, 0.909, 0.089, 0.202, 0.009, 0.010 and 0.001 respectively. Acanthus montanus is reported for its nutritional and medicinal values throughout Africa. The result of this work suggests further exploitation of the parts of Acanthus montanus to unveil more of its potential uses for the treatment of diseases.

Aims: Quantitative phytochemical, proximate and some mineral content of the leaves and stem bark of Spondia mombin, a plant commonly found in Southern Nigeria was studied with a view of ascertaining their nutritional potential and justification for their ethnopharmacological uses. Place and Duration of Study: The study was conducted in the research Laboratory of the Department of Biochemistry, Federal University Otuoke, Bayelsa State, Nigeria, between        February – March 2019. Methodology: Proximate composition, quantitative phytochemical, and mineral contents of the samples were studied using standard analytical methods of the Association of Analytical Chemist (AOAC). Results: Proximate analysis of the leaves and stem bark showed that there was no significant difference (P  between the carbohydrate and protein content of both leaves and stem bark while the stem bark had significantly higher (P values for ash, fat and fibre when compared to the leaves which incidentally had significantly higher (P  moisture content. Quantitative phytochemical analysis revealed that there was no significant difference (P  between the leaves and stem bark with reference to tannin, oxalate and phytate, the stem bark, however, showed significantly higher (P  values for alkaloids, saponin and cyanogenic glycosides when compared to the leaves, although flavonoids and phenols were significantly (P higher in the leaves. Mineral (elemental) analysis of both leaves and stem bark indicated the presence of macro and micro minerals in varying amounts. Conclusion: These findings indicated that S. mombin contained an appreciable amount of nutrients and minerals which could be included in the diet to supplement our daily nutrients and animal feeds, while the presence of the phytochemical may justify their use in ethnomedicine for the prevention, treatment and management of diverse health challenges, the phytochemicals may also act as lead compounds in the development of new drugs to counteract the present drug-resistant phenomenon.

The present study is a first report on the phytochemical analysis of the plant Fibraurea darshani which is endemic to Western Ghats. The plant is a woody dioecious climber belonging to the family Menispermaceae. Preliminary phytochemical screening of methanolic extracts of the stem of F. darshani revealed the presence of secondary metabolites like alkaloids, carbohydrates, anthraquiones, terpenoids, flavonoids, phenolics, sterols etc. A simple and reproducible high performance thin layer chromatography was developed to evaluate the presence of berberine in methanol extract of stem of F. darshani. This method involves separation of compounds by HPTLC on pre-coated silica gel 60F 254 plates with a solvent system of Chloroform: Ethyl acetate: Methanol: Formic acid (4:5:4:0.3) and scanned using densitometric scanner in UV reflectance photo mode at 254 and 366nm. The Rf values (0.97) for berberine in the plant sample and the reference standard were found comparable under UV light at 366nm. The HPTLC method developed was simple, accurate and specific.

No study has been conducted to determine the mineral content of seeds belonging to different quinoa varieties under the conditions of Turkey. In addition, there is no study on whether quinoa seeds that containing high amounts of minerals can be utilized for mineral needs of laying hens in particular. In this study, which was carried out under Erzurum irrigated conditions, it was aimed to determine the mineral content of seeds belonging to nine quinoa varieties and whether they can appropriately utilize for meeting mineral requirements (as recommended by NRC) of laying hens. Significant differences were observed in the mineral contents of the varieties. The phosphorus, potassium, calcium, magnesium, iron, copper, manganese, zinc and boron contents of the seeds varied between 0.18-0.25%, 0.76-1.08%, 0.07-0.12%, 3427-5453 mg kg-1, 233.8-577.8 mg kg-1, 45.6-107.8 mg kg-1, 40.2-72.9 mg kg-1, 29.8-55.4 mg kg-1 and 48.3-94.7 mg kg-1, respectively. When these results were compared with the values recommended by NRC, it was seen that quinoa seeds could exceedingly meet the daily mineral requirements (except calcium) of laying hens. As a result, it has been revealed that the seeds of all quinoa varieties can be evaluated as an organic mineral source in the feeding of laying hens.

The effect of the stage of maturity, cultivar, nitrate fertilization and soil type on the mineral content of sugarcane (Saccharum officinarum L.) was determined in Guadeloupe in two experiments. The calcium, phosphorus, sulfur, magnesium, sodium, potassium, zinc, copper, manganese and molibdenum contents of tops, stalks and whole plants were determined in sugarcane of 14 cultivars at two stages of maturity (8 vs. 12 mo) in an experiment in an acid soil area. The procedures were repeated in a second experiment in a calcareous soil area with two cultivars (B 69379 vs. B 744708) and three nitrate fertilization levels (80, 150, 300 kg N/ha/yr). The mean Ca, P, S, Mg, Na, K contents of whole plants were 1.27,1.86,1.88, 0.89,0.20, 5.87 g/kg dry matter (DM), respectively, in experiment 1. The mean Zn, Cu, Mn, Mo contents of whole plants were 17.2, 1.8, 89.2 and 0.4 mg/kg DM, respectively, in experiment 1. The mineral contents of tops were generally higher than those of stalks. Nitrate fertilization and stage of maturity had little effect on the mineral content of sugarcane.

African Breadfruit

The extracted seeds of African breadfruit are identified to be extremely healthy whenever it is correctly processed. Therefore, the aim of the present study was to evaluate the effects of processing methods on the nutritional quality of African breadfruit seed. A qualitative phytochemical analysis including: Alkaloid, Flavonoid, Saponin, Tannin, Anthraquinone, Terpenoids, Steroid, and Cardiac Glycosides for the different fraction of African breadfruit seed was performed using a standard method. The result revealed the presence and greater amount of phytochemical for the raw fraction; seven in eight, six in eight for steamed fraction, and four in eight for boiled and roasted respectively. Anti-nutrient, Proximate, and Mineral Content were also conducted using standard methods. The amino acid composition was determined using High-Performance Liquid Chromatography (HPLC). The results of the present study revealed that anti-nutrients including Phytate, Tannins, and Oxalate were significantly p<0.05 reduced in the boiled fraction 5.47±0.15, 3.42±0.02 and 6.89±0.05, and highest in the raw fraction 7.77±0.01, 5.09±0.03 and 9.34±0.14. The proximate composition including; percentage crude fat, Ash, Carbohydrate, Fatty acid, and Energy value were significantly lower p<0.05 in the boiled fraction relative to the other fractions. Mineral contents; calcium, magnesium, sodium, potassium, and phosphorus were also significantly p<0.05 elevated in the boiled fraction relative to the raw, steamed, and roasted fraction. The amino acid composition was highest in the roasted and boiled fraction 57.350 and 56.978, and lowest in the steamed and raw fraction 35.754 and 28.748 respectively. Therefore, boiling (cooking) is encouraged for the preparation of African breadfruit seed.

The Impact

This article draws upon research with children whose mothers were imprisoned in England and Wales, to investigate the impacts of maternal imprisonment on dependent children. The research directly engaged with children, in accordance with Article 12 of the UNCRC 1989, and is set within an examination of the differentiated treatment in the family and criminal courts of England and Wales of children facing state initiated separation from a parent. The article explores children’s ‘confounding grief’ and contends that this grief originates from social processes, experienced as a consequence of maternal imprisonment. ‘Secondary prisonization’ is characterized by changes in home and caregiver and the regulation of the mother and child relationship. ‘Secondary stigmatization’ occurs when children are stigmatized by virtue of their relationship with their mother. These harms to children call into question the state’s fulfilment of its duty to protect children under Article 2 of the UNCRC 1989.

A case is presented that shows the usefulness of integrating systems theory and attachment theory in the formulation and treatment of a clinical problem. The 5 year old son of East Indian immigrants presented with persistent psychogenic vomiting associated with pathological family attachments. It was evident that the precarious family equilibrium was stabilized by the child's psychogenic vomiting. The therapeutic team suggested to the family that their problems might be more satisfactorily resolved if the mother and child maintained their link by two-way radio. Three weeks later the vomiting had ceased, the child no longer felt that he needed the radio and both parents had established new patterns of relating to their child, whose attendance and peer socialization at school showed marked improvement. To some extent the rapid resolution of the problems was facilitated by the cultural strengths of the family.

This study determines how levels of various trace metals in wool and the colour of the fibre change as a result of sunlight exposure and treatment with chelating compounds during wool growth. Twenty-four yearling Merino sheep were clipped on the shoulders and rumps and fitted with sheep coats modified with transparent patches. Patches over the shoulder wool (one per sheep) were either polyethylene (PE) that transmits ultraviolet light or polyvinyl chloride (PVC) that excludes ultraviolet light. The rump wool on each sheep was treated either with a copper chelator treatment (kojic acid or methyl gentisate in aqueous alcohol) or aqueous alcohol only. For 12 of the sheep the rumps were exposed to sunlight through PE patches while rump wool on the other sheep was covered by the sheep coat. Wool was harvested after 11 weeks’ growth with yellowness (Y-Z) and individual mineral contents measured using the same clean wool sample. Sunlight exposure through PE patches caused a mean increase in Y-Z to 9.1 (shoulder) or 9.5–10.1 (rump) from a base level of 7.1–7.2 (shoulder) or 7.0–7.6 (rump) in wool protected by the sheep coat. In contrast, there was no significant change in Y-Z for the PVC patch (shoulder). Therefore, it appears that ultraviolet light damage caused the increased Y-Z. Most of the trace metals analysed increased in the shoulder wool exposed to sunlight but the paired differences for PVC were lower than PE. It appears that changes in fibre caused by sunlight exposure (especially ultraviolet light) facilitate adsorption of minerals from the environment, including the animal’s own suint. Application of the chelating compounds to the rump wool caused pronounced yellowing of the wool with Y-Z increase being most pronounced for kojic acid. Copper levels in the wool were reduced by kojic acid and methyl gentisate while calcium levels were increased by kojic acid and reduced by methyl gentisate. It is not clear from these findings whether minerals and copper in particular contribute to yellowing of wool. However, the different effects of sunlight and chelation on mineral contents in wool shown may well relate to alternative mechanisms of discoloration (i.e. photoyellowing versus bacterial).
