In this research, we extracted the genomic DNA from the Buxus sinica var. parvifolia leaves by using the modified CTAB approach and then used as the template DNA. Base on the invariable quantity of TaqDNA, we att empted to establish and optimize ITS-PCR amplification system for Buxus sinica var. parvifolia by employing L9 (3^4) orthogonal design with four factors, i.e. template DNA, Mg(superscript 2+), dNTPs and primer.
