From June 16^th to 18^th, the 24th World Pharmaceutical Ingredients China Exhibition (CPHI China 2026) grandly opened at Shanghai New International Expo Center. "Zhengguang" booth drew massive crowds, where a professional team delivered in-depth presentations on core products—including plant-derived drug extraction resins, pharmaceutical purification media, and peptide solid-phase synthesis medias—highlighting technical advantages and industry trends. With its strong expertise, the company won widespread acclaim from professional visitors and earned consistent recognition across the industry.

In the modern healthcare system, antibiotics undoubtedly play a crucial role as loyal "guardians" of human health. Meanwhile, “Zhengguang”’ ion exchange resins, macroporous adsorption resins, and chromatographic media are providing pharmaceutical companies with comprehensive process solutions spanning extraction to purification. These materials enable highly efficient extraction, decolorization, separation, and purification of semi-synthetic aminoglycoside antibiotics such as streptomycin, kanamycin, gentamicin, neomycin, sisomicin, and tobramycin, as well as vitamin B12, other vitamins, amino acids, and nucleotide-based drugs, offering strong support for the production of these vital medicines essential to human health.

By precisely controlling particle size, polarity, and pore diameter parameters, “Zhengguang” resins achieve efficient capture of target components tailored to the molecular characteristics of different biopharmaceutical categories.

“Zhengguang” D115 macroporous adsorption resin, with its unique pore structure and functional group distribution, can selectively adsorb antibiotics such as streptomycin, gentamicin, neomycin, and sulfamethoxypyridazine from complex fermentation broths, significantly improving adsorption efficiency compared to traditional methods.

“Zhengguang” AB-8 macroporous adsorption resin exhibits excellent adsorption and elution performance for flavonoids and saponin-type natural drugs, featuring high adsorption capacity and high product recovery.
