Component sphingoid bases of cerebrosides from leaves of twenty-two plants were analyzed by capillary GC as the corresponding fatty aldehydes. No apparent difference in the ratios of 8-E-unsaturated sphingoid bases to the 8-Z-forms was found between chilling-resistant and chilling-sensitive plants. Nevertheless, most of the chilling-resistant plants analyzed had more 8-Z-unsaturated trihydroxy base contents than those of the E-isomer.
