摘要

Rice powder containing Konjak flour made with tuberous roots of Amorphophallus konjac is imported as a rice-processed product from China to Japan. An improved DNA purification method for the polymerase chain reaction (PCR) analysis of rice in such products is necessary, since Konjak flour constituents absorb the DNA purification buffer to form a gel, and cause problems in the subsequent purification steps. Here, we present a simple preparative system for isolation of the rice and a purification method of the rice DNA from the product. The purified DNA was confirmed to be a good template for both PCR and real-time PCR.
