○ Antioxidant compounds and activities of the methanolic extracts from milling fractions of sorghum (Sorghum bicolor L. Moench)
The purpose of this study was to evaluate the antioxidant compounds and antioxidant activities of the methanolic extracts from milling fractions of sorghum. To determine the antioxidant compounds in the methanolic extract from the milling fractions, the content of polyphenol, flavonoids, tannin, anthocyanins and proanthocyanidin were measured by spectrophotometric methods. These were evaluated for antioxidative activities by ABTS and DPPH radical scavenging activities. The extraction yield of hull, bran and grain of sorghum were 9.95, 19.05 and 2.94%, respectively. The methanolic extracts from sorghum bran showed generally higher antioxidant activities than the extracts from hull and grain of sorghum. In addition, antioxidant compounds distributed much higher contents in sorghum bran extract than in the extracts from hull and grain of sorghum. A significant correlation was also noted between free radical scavenging activity and polyphenolic compounds. The results of this study show that notable antioxidant activity in sorghum bran are considered to have significant health benefits.
○ Antioxidant compounds and activities of foxtail millet, proso millet and sorghum with different pulverizing methods
We evaluated the antioxidant compounds and activity of the methanolic extracts of foxtail millet (FM), proso millet (PM), and sorghum (SG) using different pulverizing methods (pin mill and ultra fine). The particle size of the FM, PM, and SG were 102.12, 89.52, and 102.25 μm, respectively, using the pin mill pulverizer. The sizes were 9.43, 9.52, and 10.18 μm, respectively, using the ultra fine pulverizer. There was no difference in moisture, crude fat, ash, or protein content between the two different pulverizing methods. The total γ-oryzanol content of the FM using the pin mill and ultra fine pulverizers was 116.07 and 145.30 μg/g, respectively. The total polyphenol content of the SG using the pin mill and ultra fine pulverizers was 14.58 and 15.03 mg/g extract residue, respectively. There was no difference in total flavonoid or tannin content of the methanol extracts between the two different pulverizing methods. The major phenolic compounds in FM were pyrogallol, gallic acid, (+)-catechin, salicylic acid, ferulic acid, and rutin; in PM, they were pyrogallol, rutin, gallic acid, kaempfrol, and salicylic acid; in SG, they were (+)-catechin, salicylic acid, pyrogallol, myricetin, hesperidin and chlorogenic acid. SG had a higher radical scavenging activity than FM or PM extracts. The DPPH and ABTS radical scavenging activities of the SG extracts using the ultra fine pulverizer were 178.10 and 251.56 mg TE/g extract residue, respectively. We noted a significant correlation between free radical scavenging activity and polyphenolic compound.
