Contents of phytochemical constituents and antioxidant activity of 19 garlic (Allium sativum L.) parental lines and cultivars

Antimicrobial and antioxidant properties of various Greek garlic genotypes

“…The great variation in TPC content between the tested genotypes could be attributed to genotype effect when comparing different landraces and/or commercial cultivars cultivated in the same or different regions, as well as to differences in microclimate conditions and cultivation practices between the regions where the samples were collected. These results are in agreement with those reported by Bhandari, Yoon, and Kwak (2014), Chen et al (2013), and Denre et al (2013) who also reported a great variation between various garlic cultivars, as well as a positive correlation of antioxidant activity and TPC content. The correlation analysis of antioxidant activity and TPC content of our study showed significantly negative exponential correlations for all the tested assays, with reducing power assay having the highest determination coefficient (R 2 = 0.9145) and beta-carotene assay the lowest (R 2 = 0.6669) (Fig.…”

“…Apart from the differences in antioxidant activity and TPC content between the various genotypes grown in different regions, significant variations were also observed between local cultivars (G1 and G2) and local landraces (G9-G11), which further supports the effect of genotype on these parameters apart from microclimate conditions and cultivations practices that usually differ between the various growing regions. Bhandari et al (2014) have also reported significant differences in chemical composition and antioxidant activity of garlic lines and cultivars, which could be attributed to adaptation mechanisms that may be developed throughout their cultivation history, as well as to artificial selection through vegetative propagation (Hirata et al, 2015) and preharvest factors (Beato et al, 2011;Martins et al, 2016). Furthermore, Khar, Banerjee, Jadhav, and Lawande (2011) who evaluated chemical composition of various Indian garlic ecotypes, reported significant variation between different genotypes, as well as significant bulb to bulb variation, especially in local landraces where breeding status and uniformity is generally low.…”

Nutritional Value, Chemical Characterization and Bulb Morphology of Greek Garlic Landraces

“…Bhandari et al [32] evaluated 19 garlic genotypes from South Korea, and although they reported similar amounts of sucrose (up to 3.43%) to those of our study, fructose and glucose were detected in higher amounts than our study (1.05% and 0.54% comparing to 0.41 and 0.27, for fructose and glucose respectively), which could be attributed to different genotypes and growing conditions. Significant variation according to the genotype in sugar composition and total sugar content has been previously reported by Pardo et al [33] who evaluated 14 garlic cultivars cultivated in Spain.…”

Research on garlic capsule and selenium-vitamin A, vitamin B, vitamin C applied in therapy of acute hepatocellular damage in a rat model

“…In addition, garlic has long been used medicinally, most recently for its cardiovascular, anti-neoplastic, and clinical antimicrobial activities [44,45] . Studies had also shown its significant lipid-lowering effects in the liver and anti-platelet activity [46,47] . Further study suggested that garlic has no effect on drug metabolism [48,49] .…”
