ABSTRACT

Background and Objectives: Food shortages and nutritional imbalances are among the main food security problems in many countries around the world. In this study, the nutrients content of the yellow and red-fleshed sweet potatoes varieties cultivated in Nigeria were assessed. Materials and Methods: The proximate composition, mineral elements analysis, phytochemicals, and vitamins content of the red and yellow-fleshed sweet potatoes were determined using the standard methods of analysis. Results: The proximate analysis has shown that, the moisture (17.927%) and fat (2.703%) content of the yellow sweet potato were significantly (p<0.05) higher than in the red potato with a content of 16.68% and 1.693% respectively. The protein and fiber content of the red potato are 14.280% and 14.572% respectively, this is quite higher than in the yellow cultivar having 12.987% and 10.443% of the nutrients respectively. The ash and carbohydrate content were same in both. The red potato exhibits high level of sodium (11.420 mg/l), potassium (1.206 mg/l), and magnesium (8.468 mg/l) in contrast to the red potato containing 10.270 mg/l, 1.035 mg/l and 6.127 mg/l of the respective elements. Iron and zinc content were comparable in both cultivars while the calcium content (1.444 mg/l) of the yellow cultivar is significantly higher than in the red variety (1.144 mg/l). The vitamin A, B and E content of the red potato are 8.740 µmol/L, 2.977 mg/dl, and 13.267 mg/dl respectively. These values are significantly (p<0.05) higher than in the yellow potato containing 6.047 µmol/L, 1.680 mg/dl, and 11.110 mg/dl of the respective vitamins. There is no significant difference with respect to the vitamin C content of both yellow (11.850 mg/dl) and red potato (12.520 mg/dl). The phytochemicals: tannins, flavonoids, phenols, terpenes, and anthocyanins content of the red sweet potato are 0.967 mg/g, 1.577 mg/g, 1.867 mg/g, 6.590 mg/g and 2.660 mg/g respectively. Terpenes and anthocyanins were not found in the yellow cultivar. However, saponins (0.823 mg/g) were found in the yellow variety but not in the red potato. Amount of the tannins, flavonoids and phenols observed in the yellow-fleshed potato are 0.667 mg/g, 1.027 mg/g and 1.287 mg/g respectively. These values are lower than in the corresponding red potato. Conclusion: In this study, the nutritional contents of sweet potato varieties have been assessed which will immensely contribute to reducing the menace of malnutrition bedeviling the Northwestern part of Nigeria.

ABSTRACT

Background: Benign prostatic hyperplasia (BPH) represents one of the most prevalent urological disorders among older men. Medicinal plants have been used since antiquity in treating various types of human illnesses, including prostatic diseases. Despite the plethora of published ethnobotanical surveys on Nigerian medicinal plants for treating various diseases, there is a paucity of such research in the country with respect to botanical agents used in treating BPH. Aims and Objectives: The present study is aimed at obtaining ethnobotanical information regarding the use of herbs by the residents of Sokoto metropolis in the treatment of BPH. Materials and Methods: After permission from departmental ethics committee, an ethnobotanical survey was conducted on medicinal plants utilised for the treatment of prostatic hyperplasia in Sokoto state, North Western Nigeria using semistructured oral interviews. Results: Findings from this survey showed a total of 44 plant species belonging to 22 families. Among the species, Cassia sieberiana DC., Detarium microcarpum Guill. and Perr. and Lawsonia inermis L. were the most commonly utilised. The part most commonly used for BPH are the stembark, followed by the roots. Seeds, leaves, and bulbs were found to be infrequently used. Irrespective of the plant parts used water was the most frequently employed medium of extraction. Though less popular, fermented milk, fermented milk-millet mixture, and a traditional cereal-based beverage were also employed. The most common modes of preparation were decoctions and infusions, while oral was the main route of administration. Conclusion: This survey documented 44 plant species used traditionally in Sokoto metropolis as a remedy for BPH. Further studies are recommended to confirm the efficacy and evaluate the mechanisms of action of standardized formulations of the herbal recipes individually and in combination.

ABSTRACT

Background: Benign prostatic hyperplasia (BPH) is defined as a progressive nonmalignant enlargement of smooth muscle and epithelial cells in the prostate. A lot of studies have been published on the efficacy and safety of phytotherapeutic agents against BPH, making it a daunting task to review comprehensively. Aim and Objectives: The present article aimed to review the existing systematic reviews of primary studies on the subject. Google Scholar and PubMed databases were used in searching the articles. Materials and Methods: After permission from the departmental ethics committee, the quality of the retrieved articles was assessed using a revised assessment of multiple systematic reviews scale. Results: Sixteen reviews were included, with the majority (11 out of 16) focusing on Serenoa repens extracts. Such evidence for other phytotherapeutic agents studied is either limited, conflicting, or lacking. Issues about the primary studies included in the reviews were discussed and some recommendations presented. Conclusion: The reviews that focused on the most widely studied hexanic extract of S. repens, Permixon, were consistent in their conclusions that the extract is beneficial in improving the symptoms of BPH.
