Abstract: 

In plants, secondary metabolites and polysaccharides interfere with genomic isolation procedures and downstream reactions such as restriction enzyme analysis and gene amplification. The removal of such contaminants needs complicated and time-consuming protocols. In this study, a simple, rapid and efficient method for leaf DNA extraction was optimized. This method use small amount of plant material to reduce inhibitory agents (alkaloids, phenolic). The procedure involves homogenization of the plant leaf in extraction buffer, incubation at 60°C, extraction by chloroform: iso-amyl alcohol and finally DNA precipitation by cold isopropanol. The results showed that the extracted DNA could be used directly for PCR.
