Effects of Wood Vinegar Components on Antioxidation and Seed Germination
The mongolian oak wood vinegar was analyzed by gas chromatography-mass spectrometry(GC-MS).The results showed that the relative content of 3-methyl-tetrahydro-furan in dichloromethane refined wood vinegar was the highest,41.60%.The next is guaiacol,the relative content is 8.73%;Phenol,relative content 6.79%.The antioxidant experiment showed that when the mass concentration of mongolian oak wood vinegar was 4 g/L,the absorbance of total reducing power reached 0.067,the DPPH∙ scavengingrate was 37.8%,and the ∙OH scavenging rate was 14.1%.The seed germination experiment showed that the seed germination rate of mongolian oak wood vinegar diluted 2000 times was significantly different from that of the control,and the seed germination rate of four nine cabbage heart,purple flowering stalk and pakchoi increased by 15%,17%and 23%respectively.Mongolian oak wood vinegar has certain antioxidant activity and allelopathy.Phenols in mongolian oak wood vinegar are the main substances for antioxidation and seed germination.
