  • Title: [Primary effects on Isatis indigotica after spaceflight].
    Author: Chen XD, Lan J, Wang XG.
    Journal: Zhong Yao Cai; 2007 Apr; 30(4):381-3. PubMed ID: 17674782.
    Abstract:
    Isatis indigotica carried by the Chinese first spaceship "Shenzhou" was studied in order to find the mutation after spaceflight. TLC differentiation experiments showed no distinct discrepancy among the samples of spaceflight and non-space-flight, and the same color spot appeared corresponding to the location of the arginine. Isoenzymes of esterase and peroxidase were studied with PAGE. Isoenzymes of esterase were difference among the samples. To peroxidases, little difference was found with them. The ratio of dry weight and extract contents showed out the mutation has emerged after spaceflight, but some characters were unstable. It is necessary for further study.
