Response to SOD of Aloe vera var.chinensis(Haw)Berg.by formaldehyde
The present paper is aimed to report the authors' pioneering experiments with the absorption of formaldehyde by Aloe and the activity changes of the super-oxidedismutase( SOD) in its leaves so as to unveil the physiological reasons why the Aloe can absorb formaldehyde in the room environment. Our experiments have done in a glass testing chamber in hoping to simulate the interior room condition. The formaldehyde concentration in the simulated room can be measured by using a method of acetyl acetonation with spectrophotometer with the activity of SOD being tested by the self-oxidization method of pyrogal-lic acid. The results of our experiments indicate that in the presence of Aloe vera var. chinensis (Haw) Berg., the formaldehyde concentration in the simulated room would have given a remarkable drop; while the activity of SOD would turn to be more and more remarkable with the increase of formaldehyde absorption capacity of Aloe. From what is said above, it can be concluded that the SOD in Aloe vera var. chinensis (Haw) Berg, has a physiological stress response to the stress of formaldehyde, in which Aloe did play a certain role in depurating formaldehyde in the interior environment.
