i am extracting RNA using Easy pure RNA kit. I am getting good concentration of RNA around 300 ng/ul with good 260/280 value, but i am getting very low 260/230 ratio. Despite this, the quality of extracted RNA on gel seems good.

i tried many things like 2 washing steps, more centrifuge time with empty column to remove ethanol residues, more time for air drying the column but still getting varying results.
