AI Article Synopsis
- A study investigated the phytotoxic and antioxidant effects of dichloromethane (DCM) fractions from leaves, leading to seven sub-fractions through chromatography.
- Two sub-fractions, DCM6 and DCM4, demonstrated strong phytotoxic activity at a concentration of 125 µg per plate.
- The antioxidant effectiveness of DCM and DCM4 surpassed that of a common synthetic antioxidant, while GC-MS analysis identified key compounds like methyl palmitate and methyl oleate that may contribute to these effects.
Article Abstract
Dichloromethane (DCM) fraction and sub-fractions obtained from leaves were examined in order to determine their phytotoxic and antioxidant effects. The dichloromethane fraction was submitted to a preparative layer chromatography leading to seven sub-fractions (DCM1-DCM7). Gas chromatography-mass spectrometry (GC-MS) was performed on the dichloromethane sub-fractions. The DCM sub-fractions presented phytotoxic potential; at a concentration of 125 µg per plate, DCM6 and DCM4 showed the strongest results on and respectively. The DCM fraction and DCM4 sub-fraction were more effective than 2,6-di-tert-butyl-4-methylphenol (BHT) at scavenging the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. Analysis by GC-MS showed the presence of methyl palmitate (33.05%) in DCM4 and methyl palmitate (17.29%) and methyl oleate (50.96%) in DCM6, suggesting that the activities exhibited by the sub-fractions may be attributed, at least partially, to these major compounds. These results indicate that the DCM sub-fractions of could be used as natural herbicides and antioxidants.
