Comparison of methods for isolating high quality DNA from sage (Salvia officinalis)

A number of protocols have been reported for efficient plant DNA isolation. However, many of these methods are often species dependent. Several protocols described for DNA isolation from medicinal herbs and aromatic plants fail to produce good quality DNA. These plants contain exceptionally high amounts of secondary metabolites which interfere with DNA isolation. To address this problem, CTAB-modified protocols were...
