Chop the tissue into a paste using a clean single edge razor blade. The suitability of ethanol (96% v/v) as a preservative solution prior to DNA extraction was evaluated using leaves of Jatropha curcas and other tropical species. The extraction was done using two solvents namely, ethanol and methanol according to the procedure described by Goossens and Marion, (2011) [16]. Methodology; Open Access; Published: . Place the tube in a 60C water bath for 30 minutes. The greatest extraction yield was obtained using maceration technique compared to other extraction methods which reduces the extraction time and provides extracts with higher antioxidant activity (Table 1). While many DNA extraction methods exist that contend with the presence of phenolics and polysaccharides, these methods rely on . Quality of plant extract depends on plant material, choice of solvents and the extraction methods. It may suggest that microwave method using ethanol 70% is suitable for fast extraction of . get higher yields the process has to be optimized.
