Abstract

Background and Objective: Quality of DNA is usually determined by multiple factors such as pollution especially caused by RNA, protein, lipid and other structures that inhibit Taq polymerase enzyme in polymerase chain reaction (PCR) and inhibit the cutting enzymes. The existence of phenolic compounds and other secondary metabolites has many effects on the quantity and quality of the purified DNA. At this investigation, in terms of quality and quantity with an efficient method for purification of DNA from S. marianum L. plant leaves, taking into account existing limitations to be provided.Subjects and Methods: In this study quantitative and qualitative comparison between two DNA EXTRACTION methods namely sodium dodecyl sulfate (SDS) and a modified cetyl trimethylammonium bromide (CTAB), were undertaken. The quantity of extracted DNA was determined by measurement of the absorption rate in wavelengths of 260 and 280 nm and their ratios by spectrophotometer. For investigate DNA quality the existence of RNA fracture was evaluated by agarose gel.Results: In terms of quantity and quality, for DNA EXTRACTION from S. marianum Populations, CTAB METHOD had low performance While, SDS METHOD showed appropriate performance in terms of quantity, quality and purity of extracted DNA.Conclusion: ANOVA of samples revealed that the purification method, races and their interaction is very significant and showed that the purification of the races and their interaction had an impact on the quality of purified DNA. The 280A/260A ratio that is more than 2 indicates the presence of RNA and DNA degradation. Also if this ratio is less than 1.8 Indicating the presence of protein contamination in DNA. In genetic engineering researches and genetic studies, the suitable methods for DNA purifying are those that get higher quantity and quality of net DNA. Many studies carried out on MEDICINAL PLANTs and plants which contain high level of polyphenol and polysaccharide compounds showed that CTAB METHOD and other methods that are technically same to CTAB have better efficiency. CTAB as a detergent can form complex with the DNA and can separate it from carbohydrates and proteins. The remaining polysaccharides are removed by concentrated NaCl.
