Differential Localization of Gossypitrin and Herbacitrin in Equisetum Sporelings

抄録

When the spore of Equisetum arvense is immersed in 0.1 M KOH solution, the cytoplasm is colored yellow, and the colored matter is naturally extracted into the medium. After germination, the same coloration with KOH takes place in the basal cell of protonema but not in the apical cell. The colorecd matter was taken out from the spore with aceton followed by methanol and ether, then it was analyzed by paper-chromatography and by column-chromatography. The analyzed components were separately examined by use of UV absoption and IR absorption spectometries. As a result, the colored matter was identified to be consisting of gossypitrin and herbacitrin. Role of these two substances in the cell of Equisetum is not clear, while presumed to take part in regulation of morphogenesis.
