“…Chen et al (2013) reported similar results that variability of TPC and TFAC in bulbs of different cultivars could be attributed to various cultivar characteristics. In agreement with our results, previous reports have shown that different garlic cultivars had different yields, allicin content (Khar et al, 2011), and polyphenolic content (Lu et al, 2011). These results are in accordance with total phenolic acid content of a local garlic cultivar grown near Namhae-gun, Korea.…”

Flavonoids and phenolics are compounds with hydroxyl groups (-OH) bound to aromatic rings which enable them to react with reactive oxygen species and eliminate free radical activity. Single bulb garlic (Allium sativum var. solo garlic) is known to have antioxidant activity which comes from the phenolic groups. This study aims to determine the correlation of total flavonoid and phenolic levels with the antioxidant activity of ethanolic extracts from single bulb garlic grown in Magetan and Tawangmangu regions. This study included an observational analytic study with a cross-sectional design. Total flavonoid levels were measured by colorimetric method and total phenolic levels were measured by Folin-Ciocalteu method using Spectrophotometry UV-Vis. Antioxidant activity was measured by DPPH method at a wavelength of 517 nm. The data analysis used was multiple linear regression. The results showed that the extract of single bulb garlic from Magetan had total flavonoids of 12.1833 ± 0.1943 mg QE/gram, total phenolics of 70.244 mg GAE/gram, and antioxidant activity with an IC50 value of 20,216 ppm. The extract of single bulb garlic from Tawangmangu contained total flavonoids of 14.4833 ± 0.5911 mg QE/gram, total phenolics of 92.222 mg GAE/gram, and antioxidant activity with an IC50 value of 13.777 ppm. The conclusion of this study is that there is a significant correlation of total flavonoid and total phenolic content with antioxidant activity.

“…According to Etoh and Simon (2002), only limited genetic variation can be introduced via mutations and it is very hard to make significant progress by mutation breeding alone. However, Khar et al (2011) and Senula and Keller (2000) reported that garlic exhibits a wide range of diversity in morphological, reproductive and bulb traits because of its apomictic nature which leads to the existence of extensive somatic mutations (Ata, 2005). It was further indicated by Jabbes et al (2012) that garlic presents, in spite of its vegetative multiplication, a great diversity from agro-morphological and biochemical point of view (Abdoli et al, 2009;Burba and Gomez Riera, 1997;Hong, 1999;Lallemand et al, 1997;Messiaen et al, 1993;Ovesna et al, 2007 andStavelìkova, 2008.).…”

Garlic (Allium sativum L.) is an important edible bulbous crop with unique culinary and medicinal purposes. It is a major cash crop widely cultivated in Libokemkem and other districts of South Gondar zone of Amhara Region in Ethiopia. However, productivity of garlic in Ethiopia in general and in South Gondar Zone in particular is very low largely due to the use of unimproved local cultivars and traditional cultural practices. Five different improved cultivars of garlic were then evaluated for yield and yield components under rain-fed production practice. This acclimatization and performance evaluation at three different locations (Angot, Ginaza and Woreta) was laid in randomized complete block design with three replications. Cultivar Adiszemene local (55.44, 39.82 and 22.28 quintal per hectare (q/ha)) produced consistently high dry bulb yield at the three locations. Cultivar Chefe was found to be the lowest yielding at Angot (16.07 q/ha) and Ginaza (22.56 q/ha), whereas cultivars Kuriftu (11.92 q/ha) and Tsedey (10.06 q/ha) were the lowest yielding at Woreta indicating profound effect of environment on yield. Overall result revealed that statistically significant (P<0.05) high dry bulb yield (39.18 q/ha) was recorded in cultivar Adizemene local, followed by cultivar Holleta (31.32 q/ha). These cultivars with consistent high performance and wide adaptability would then be demonstrated and popularized for wide spread cultivation.

“…Although some studies have investigated phenolic compounds and antioxidant activity in garlic, very few reports have compared the distribution of phenolic compounds among garlic cultivars in China, or between garlic bulbs and bolts among these cultivars. It is necessary to assess this trait in garlic germplasm resources to assure their effective utilization [21] – [24] .…”

Evaluation of Garlic Cultivars for Polyphenolic Content and Antioxidant Properties

et al. 2013

Two phenolic compound parameters (total phenolic and flavonoid contents) and 5 antioxidant parameters (DPPH [2, 2-diphenyl-1-picrylhydrazyl] radical scavenging activity, HRSC (hydroxyl radical scavenging capacity), FRAP (ferric ion reducing antioxidant power), CUPRAC (cupric ion reducing antioxidant capacity), and MCA (metal chelating activity) were measured in bulbs and bolts of 43 garlic cultivars. The bulbs of cultivar ‘74-x’ had the highest phenolic content (total phenolic, flavonoids) and the strongest antioxidant capacity (DPPH, FRAP, and CUPRAC), followed by bulbs of cultivar ‘Hanzhong purple’; the bulbs of cultivar ‘Gailiang’ had the lowest phenolic content and antioxidant capacity (FRAP, CUPRAC, MCA). The bolts of ‘Hanzhong purple’ also had higher phenolic content. Principal components analysis (PCA) separated the cultivars into 3 groups according to phenolic and flavonoid contents and strength of antioxidant activity. The first group had higher HRSC, FRAP, and flavonoid content; the second group had higher total phenolic content and MCA; some cultivars in the third group had higher HRSC and FRAP. All 8 test garlic bulb extracts successfully prevented Human Vascular Endothelial Cell death and significantly prevented reactive-oxygen species (ROS) formation in oxidative stress model, in which cultivar ‘74-x’ had highest protection capability, following by cultivar ‘Hanzhong purple’, and the bulbs of cultivar ‘No. 105 from Korea’ had the lower protection capability against cell death and ROS formation. The protection capability in vivo of these garlic cultivars was consistent with their phenolic content and antioxidant capacity.
