“…Notably, the values obtained for iron (9.5-9.9 mg/100g) for leaves from both sexes fall within the recommended dietary allowance (RDA). This further support the indigenous beliefs among many Nigerians that ugu leaves are sources of blood and extracts from the leaves are given to anemic individuals to increase their packed cell volume (PCV) and for prevention and amelioration of sickle cell disease in infants and adults [11], [13], [14] [15]. In a healthy diet, fibre helps to remove harmful cholesterol from the arteries, reducing the risk of heart disease, aid in digestion, combats diabetes [16].…”

Fluted pumpkin (Telfairia occidentalis Hook. F), is an under-utilized leafy vegetable cultivated and consumed for its valuable nutrients and minerals playing a crucial role in combating micronutrient deficiencies. This shrub is dioecious, exhibiting distinct differences in sexual morphology. The study aims to contrast the phytochemicals, physico-chemical and mineral profiles of the female and male fluted pumpkin leaves. Seedlings of fluted pumpkin were evaluated at National Horticultural Research Institute (NIHORT), Ibadan, Nigeria using a randomized complete block design with three replications. Fresh leaves were harvested at flowering from identified male and female vines for nutrient composition analysis. Beta-carotene, sodium and fibre content were notably higher in female leaves, whereas vitamin C, minerals, and anti-nutrients were more abundant in the male leaves. The concentrations of phenolic, flavonoid, vitamin C, tannin, saponin, and certain minerals emerged as the most influential factors for distinguishing between the sexes. Hence, leaves from both sexes can contribute to an enhanced diet as both sexes harbor valuable genetic traits that could be harnessed for the nutrient improvement of fluted pumpkin varieties.

“…Initially, T. occidentalis was wild throughout its current range; nevertheless, wild plants may have been harvested to local extinction and are now substituted with cultivated types [6,7]. T. occidentalis is a nutritious vegetable widely cultivated for its palatable and nutritious leaves and seeds and contains essential nutrients that can play a major role in human nutrition [8,9]. T. occidentalis find numerous applications in different industries, such as food and medicine [10][11][12].…”

The cucurbitaceous vegetable Telfairia occidentalis Hook. f. “Fluted pumpkin” is grown in West Africa, especially in Nigeria for its nutritious leaves and seeds. It has various industrial applications, such as food and medicine. T. occidentalis contains essential nutrients that could play a significant role in human nutrition. Based on its chemical composition and nutritional properties, it can be used to overcome malnutrition. T. occidentalis leaves and seeds are rich in phenolic compounds, minerals, vitamins, proteins, essential amino acids, and other essential phytochemicals which can play a regulatory and functional role. The leaves and seeds of this plant have also been used in different food applications. This chapter highlights the reported knowledge relevant to the use of T. occidentalis as a food fortificant and therapeutic agent based on its prominent biological activities and the presence of phytochemicals. However, conventional food fortification methods do not completely meet the functional requirements for bioactive compounds. They also have unsatisfactory flavor profiles, as well as poor stability and bioavailability. These disadvantages can be mitigated by encapsulating the bioactive components in nanoparticle-based delivery systems. Nanofood fortification has a wide range of advantages in the protection of phytochemicals through the use of an encapsulation technique, and some micronutrients that are rapidly degraded or not properly absorbed by the body can also be aided by food fortification on the nanoscale. Nanosuspensions, nanoemulsions, nanoliposomes, and cyclodextrin carriers are some of the various nanotechnology techniques that can be used for food fortification, which have been discussed in this chapter.

“…A concoction prepared from the fresh leaves is administered to remedy acute anaemia and impotence in men (Ajayi et al ., 2004; Anchal et al ., 2014; Famuwagun et al ., 2017; Ogwu et al ., 2017). The leaves are rich in essential amino acids, minerals, vitamins and proteins (Cyril-Olutayo et al ., 2019). Oils derived from the seeds have been documented as potential feedstock for the manufacture of vegetable oils, margarine, soaps, candles and lubricants (Agatemor, 2006; Odiaka et al ., 2008).…”

Fluted pumpkin (Telfairia occidentalis Hook F.) is an underutilized indigenous leafy vegetable with enormous prospects for food security in sub-Saharan Africa. However, relatively little is known about genetic relationships and population structure in the species. In this study, 32 landraces of fluted pumpkin collected across three southern geographical regions in Nigeria were assessed for genetic diversity and population structure using 8 start codon-targeted (SCoT) makers. The polymorphic information content of the SCoT markers ranged from 0.48 in SCoT36 to 0.94 in SCoT28, with an average of 0.77. Hierarchical cluster dendrogram based on Ward's method and principal component analysis grouped the landraces into four clusters without affiliation to provenance. Overall, the mean values of the population genetic diversity parameters – Nei's gene diversity (H) and Shannon's information index (I) showed values of 0.28 ± 0.01 and 0.43 ± 0.02, respectively, implying a narrow genetic base for the landraces. The result was further corroborated by a very close Nei's genetic distance and identity among populations of the landraces. Furthermore, the south-west population exhibited the higher genetic diversity (H = 0.31 ± 0.02 and I = 0.45 ± 0.03). Population structure analysis inferred three subpopulations for the accessions with varying degrees of allelic admixture. An analysis of molecular variance revealed that almost all the genetic variation occurred within (99%) than between (1%) populations. The findings shed light on the genetic diversity of southern Nigerian fluted pumpkin and have significant implications for the characterisation, conservation, exploitation and improvement of the species.
