“…In contrast, another study on blackcurrant leaves reported the TP content and antioxidant capacity were higher in leaves picked during June (Tabart et al, 2006). Similarly, in another study conducted on blackcurrant leaves, the total phenolic content was higher in mid June, followed by a considerable decrease until early August (Nour, Trandafir, & Cosmulescu, 2014). A reason for the differences in our results to these two studies might be attributed to variation among genotypes used, as well as the age of the plant material, as in present study the leaves were sampled from fresh annual shoots.…”

The main objective of this study was to investigate the proximate, mineral and phytochemical compositions of sweet corn cob (SCC), often neglected and regarded as agricultural waste. Compositional analysis showed that more than 60% of SCC was composed of insoluble dietary fibre, with cellulose being the major constituent. Results also showed that SCC can be a good source of non-essential protein and minerals (phosphorus, potassium and manganese). SCC had a total phenolic content of 6.74 g GAE kg À1 dry weight (DW), of which bound phenolics were predominant. The bound phenolics fraction showed the highest antioxidant capacity in all three antioxidant capacity assays (TEAC, FRAP and DPPH) and contained the highest amount of ferulic and p-coumaric acid. The main carotenoids present in SCC were b-carotene, zeaxanthin and lutein. This investigation shows that SCC can be a potential source of natural colorant (carotenoids), antioxidants (phenolics) and nutritional supplements (proteins and phytochemicals).

“…Extraction and purified of polysaccharides from the leaves of G. bicolor was performed according to a previous method (Nour et al, 2014). Briefly, the dry powdered leaves (10 g) were separately suspended in distilled water at the established volume and then stirred for extraction at the established temperature and time.…”
