Separation and purification of PNS from Sanqi extract by a rosin-based polymer microsphere
Panax notoginseng saponins (PNS) is a natural medicine known for its ability to promote blood circulation, remove blood stasis, reduce swelling, and relieve pain. However, obtaining high-purity PNS from the crude extract of the medicinal plant Sanqi is a challenging and important task. In this study, a novel rosin-based diatomite polymer microsphere (RDPMs) was synthesized, and its physical and chemical properties were characterized using various analytical techniques. The adsorption capacity of RDPMs for PNS was 273.69 mg·g−1, with an increase in PNS content from 44.38 to 79.59%. The process was spontaneous, endothermic, and multilayered, controlled by physical and chemical factors. Quantum chemical calculations revealed that there are van der Waals forces, H-bonding, and electrostatic interactions between RDPMs and PNS. Overall, RDPMs is an effective and reusable bioadsorbent with potential for isolating PNS from Sanqi extract.
期刊介绍：
Colloid and Polymer Science - a leading international journal of longstanding tradition - is devoted to colloid and polymer science and its interdisciplinary interactions. As such, it responds to a demand which has lost none of its actuality as revealed in the trends of contemporary materials science.
