“…Genetic factors, abiotic factors such as environmental factors and soil conditions, and their interaction are known to affect the fatty acid composition of plant seed oils [23][24][25][26][27]. In this research, S. mukorossi seed oil-related variables including 100-seed weight, 100-kernel weight, and 100-oil weight were significantly negatively correlated with annual maximum temperature and annual precipitation.…”

Sapindus mukorossi is widely distributed in tropical and subtropical areas of southern China; the seed kernel oil is potential biodiesel material, and the saponins extracted from fruit pericarp are very valuable efficient natural surfactants. Therefore, S. mukorossi is an ideal tree species for developing forestry bioenergy and multiple other products. In this study, 42 S. mukorossi fruits from mother trees were collected from 39 distinct locations in 12 Chinese provinces to infer fruit and seed trait responses to environmental factors. Canonical correspondence analysis (CCA) was conducted using 21 horticultural fruit traits and 10 environmental factors that represented different climatic and geographic conditions throughout southern China. CCA revealed well-developed patterns of natural phenotypic variation, and insight into the ecological factors that are potentially important in shaping this variation. The results presented here further elucidate the natural distribution and ecological adaptations of wild S. mukorossi resources, which will be valuable for S. mukorossi cultivation by helping identify ideal planting areas. The germplasm resources with extensive morphological variation can also contribute to S. mukorossi breeding in the future by helping develop new cultivars with high saponin yield.

“…The USA and ID2 had similar fatty acid profiles, high in polyunsaturated fats (72.7-75.1%), low in saturated fat (20.5-22.2%), polyunsaturated fats for Ethiopian samples was 88% (Geleta et al, 2011). The USA and commercial sample, contained high levels of linoleic acid (18:2n6) as the major fatty acid (71.3-70.9%).…”

“…This likely resulted from differences in drying and storage given the age of the seeds. The amount of total lipids was the highest in ID1 (38.2%) followed by the USA and ID2 (36.7 and 36.5%, respectively) ( Table 2), mean values from Ethiopian grown seeds was 38.9% (Geleta et al, 2011). Results of this analysis also showed that niger seeds can be a significant source of proteins, the USA sample contained the highest levels (28.2%), followed by ID2 (26.6%) with ID1 showing the lowest values (18.3%) ( Table 2).…”

“…The protein-rich meal which remains after oil extraction is used as animal feed, manure or fuel [7]. In addition to its oil, the crop offers an important source of seed protein [8] that significantly contributes to the human dietary protein intake [9]. The oil of niger seeds appears to be nutritionally valuable, as condenser was used for digestion of powdered niger seed samples.…”

ABSTRACT. The levels of essential and non-essential metals in niger seed (Guizotia abyssinica (L. f.) Cass.) cultivated in different parts of Ethiopia were determined by flame atomic absorption spectrometry after wet digestion using 2.5 mL of HNO3 (69.5%), 1 mL HClO4 (60%) and 0.5 mL of 30% H2O2 at 210 o C for 150 min. Sampling was carried out randomly from nine different sites from Ethiopia and one sample from Eretria for comparison. The following metal concentration ranges (μg/g) were determined in niger seed samples, respectively: Na (159-736), K (5594-8203), Ca (340-680), Mg (2404-4656), Mn (13.4-34.3), Fe (31.6-370), Cu (9.5-61.2), Zn (23.4-46.2), Cr (4.0-16.8), Co (4.9-27.3), Ni (13.0-32.4), Pb (15.5-19.3) and Cd was not detected in all the samples. The analysis of variance indicated the presence of significance difference at 95% confidence level among niger seeds collected from different sites. Pearson correlation coefficients indicated that there were significant correlations among some metals in the niger seed. The study revealed that niger seed is good source of essential metals and free from toxic metal such as Cd and hence safe for human consumption. Generally, the metal concentration in niger seed is comparable with other oil seeds.
