Abstract: A method for separating one liquid from a mixed liquid containing at least a first liquid and a second liquid having a different boiling point from that of the first liquid, the method including: spraying the mixed liquid from a spraying means for spraying the mixed liquid, into a container into which a heated gas, having a temperature higher than at least one of the boiling point of the first liquid or the boiling point of the second liquid, is supplied from a heated gas supply means, the container having a discharge port for discharging at least a gas; vaporizing at least the first liquid by allowing the mixed liquid sprayed into the container to contact the heated gas; discharging, through the discharge port of the container, at least a mixed gas that contains the first liquid vaporized in the vaporizing; and separating liquid from the mixed gas.

Abstract: A method to reduce the content of unsaturated fatty acids in latex or a resin component, wherein the amount of unsaturated fatty acids in a plant body of Parthenium argentatum or Taraxacum kok-saghyz is reduced by lowering the expression level of fatty-acid desaturase in Parthenium argentatum or Taraxacum kok-saghyz by an antisense method or an RNAi method; a transgenic plant of Parthenium argentatum or Taraxacum kok-saghyz introduced with an expression vector in which a gene sequence encoding an antisense RNA or an siRNA having a nucleotide sequence complementary to an mRNA of a fatty-acid desaturase gene has been integrated into a site downstream of a promoter; and a method to reduce the content of unsaturated fatty acids in latex or a resin component, wherein the latex or the resin component is recovered from the above-mentioned transgenic plant.
