Macroporous adsorption resin specification standards, residue limits, safety in strict accordance with the national drug evaluation center "macroporous adsorption resin separation and purification of traditional Chinese medicine extraction" requirements, styrene skeleton macroporous adsorption resin residue: benzene <2ppm, toluene <890ppm, dimethyl <2170ppm.The total residue of styrene, alkane, diethyl benzene and resin is lower than the national standard or the international standard.The safety of non - benzofenyl matrix macroporous adsorbents should be increased in animal experiments.It is suggested that the specific column amount, specific adsorption amount, specific elution amount, retention rate and purity should be used to evaluate the purification effect of adsorption resin, so as to prevent the leakage of effective ingredients.In general, the purification of the same drug macroporous resin, its adsorption capacity decreased to less than 30%, the resin should not be reused.
