The resin provided by the invention is of a white semitransparent spherical structure, the
water content is 55%-70%, the
particle size distribution is 0.425-1.00 mm, the specific surface area is 560-750 m < 2 > / g, the
pore diameter is intensively distributed in a region of 10-30 nm, and the average
pore diameter is 9.35-10.35 nm. The resin is of a white semitransparent spherical structure, the
water content is 55%-70%, the
particle size distribution is 0.425-1.00 mm, the specific surface area is 560-750 m < 2 > / g, the
pore diameter is intensively distributed in a region of 10-30 nm, and the average pore
diameter is 9.35-10.35 nm. The resin has the characteristics of high
porosity, high specific surface area and uniform resin pore size distribution. In the same technological process for preparing
scutellarin through extraction and chromatographic purification of
erigeron breviscapus; the resin (the
scutellarin adsorption rate is 90.12%, and the product content is 90.33%) is higher in purification efficiency and wider in application range compared with common industrial macroporous adsorption resin ADS-2 (the
scutellarin adsorption rate is 19.16%, and the product content is 73.20%), HPD450 (the scutellarin adsorption rate is 21.34%, and the product content is 81.38%), AB-8 (the scutellarin adsorption rate is 15.01%, and the product content is 79.11%) and D101 (the scutellarin adsorption rate is 10.29%, and the product content is 78.68%).
