“…All of the leek cultivars tested contained significant levels of phenolics (Table 2) and compare favourably against those of the sister species onion (2-30 mg GAE g À1 dw) and garlic (20 mg GAE g À1 dw) (Gorinstein et al, 2009;Kahkonen et al, 1999). The TP content in the white shaft and green leaves of the 30 leek cultivars varied from 5 to 14 mg GAE g À1 dw and from 5 to 15 mg GAE g À1 dw, respectively.…”

“…Generally, the DPPH values for the green leaves were significantly higher than those measured in the white shaft of leek, except for the cultivars Miracle F1, Breugel F1, Poribleu, Pretan F1, Buelens, Apollo F1, Farinto, Arkansas, Kenton F1 and Fahrenheit F1, where no significant difference was measured. Gorinstein et al (2009) investigated the antiradical activity against the DPPH radical for the Allium species garlic, red, white and yellow onion: 7 lM TE g À1 dw, 22 lM TE g À1 dw, 21 and 20 lM TE g À1 dw, respectively.…”

a b s t r a c tExtracts of the white shaft and green leaves of 30 leek cultivars were investigated for their antioxidant properties, total phenolic (TP) and L-ascorbic acid (AA) content. The measured antioxidant properties included free radical scavenging activities against peroxyl (ORAC) and 2,2-diphenyl-1-picrylhydrazyl radicals (DPPH) and their Fe 3+ reducing capacity (FRAP). The results from this study suggest that the green leek leaves generally have significantly stronger antioxidant properties than the white shaft. Correlation analysis between the TP and the AA content and the antioxidant activity showed that phenolics and ascorbic acid contribute significantly to the antioxidant activity of leek. The three antioxidant activity assays were all correlated for the extracts of the white shaft of the 30 leek cultivars. Principal component analysis (PCA) elucidated the influence of part and type of cultivar on the antioxidant capacity, TP, and Lascorbic acid content, whilst the breeding strategy and seed company had no influence.

“…The peaks at 1000-1200 cm À1 correspond to C-O/C-OH single bonds of alcohols [39,40] and phenols [41]. The absorbance peak at 1055-1066 cm À1 corresponds to C-N stretching vibration of aliphatic amines or to alcohols/phenols [22].…”

Here, Syzygium cumini leaf extract (LE) and seed extract (SE) were explored for the synthesis of gold nanoparticles (GNP). LE and SE as well as their polar (water) fractions showed potential for GNP synthesis. Comparative synthesis kinetics and morphological characterisation studies revealed the synthesis of smaller sized GNP by LE than SE. Only polar (water) fractions showed potential for GNP synthesis, which are smaller in size compared to their respective extracts. SE contained more polyphenols and biochemical constituents than LE and therefore, showed higher synthesis rate and bigger sized GNP. Atomic force microscope and scanning electron microscope analysis indicated that both extracts and their fractions catalysed the synthesis of spherical GNP. The average size of GNP synthesised by LE, leaf water fraction (LWF), SE and seed water fraction (SWF) were 24, 23, 35 and 32 nm, respectively. Fourier transform infrared analysis identified the biomolecules involved in the synthesis and stability of GNP. This study documented the potential of S. cumini for the synthesis of GNP in addition to silver nanoparticles (SNP). However, nature and types of polyphenols involved in GNP synthesis seem to be different from that involved in SNP synthesis. This might be the possible reason for smaller sized GNP that SNP.

“…The absorbance was measured with 756 PC UV-visible spectrophotometer (Shanghai Yuefeng Instruments & Meters Co., Ltd.). ABTS + free radical scavenging assay: The ABTS radical scavenging assay was calculated based on [24] with some modifications. First the radical solution was prepared by mixing both the stock solutions such as 7 mM aqueous solution of ABTS and 2.45 mM potassium persulfate (K2S2O8) solution at a ratio of 1:1 [25].…”
