Genomic DNA extraction is an important aspect of plant molecular biological research. The objective of the study
was to recommend the cheap and efficient genomic DNA extraction method for some kobiraki medicines in
Bangladesh. The modified plant genomic DNA extraction methods extracted drupe, pome, hespiridium, pepo and
complex fruits. Extraction kit (Qiagen) method were applied with eight different ayurvedic medicine powder such
as Phyllanthus emblica, Withania somnifera, Abroma augusta, Syzygium cumini, Oroxylum indicum, Chrysogenum
aurium, Mucuna pruriens, Terminalia bellirica. Based on the quantity of the extracted genomic DNA tested by
measuring the absorbance at 260 nm using Nanodrop® ND-1000 spectrophotometer, quality determined by the
ratio of A260 / A280 and the amplifiable quality of DNA determined by the horizontal agarose gel electrophoresis
using 1% agarose in TBE buffer at constant voltage of 60V, the method explained by Cheng et al and the Genomic
DNA extraction kit yielded good quality DNA with satisfactory concentration for all the powder medicine tested.
Therefore the modified method of Cheng et al, 1987 could be recommended for the efficient and cost effective
DNA extraction from fruit species instead of the commercially available expensive and chemically hazardous DNA
easy plant kit method.
