In the field of traditional Chinese medicine testing, precision and reliability are key. As a commonly used traditional Chinese medicine, the quality testing of Poria cocos is related to the efficacy and safety of drugs and health products. COSMOSIL Poria cocos detection column, with excellent technical design and stable performance, has become a key tool for Poria cocos detection, providing efficient and accurate solutions.
1、 Technical principle: Targeted recognition, efficient separation
The COSMOSIL Poria cocos detection column is based on liquid chromatography technology, with the core being the specific interaction between the column packing and Poria cocos components. Through a special bonding process, secondary/tertiary amine functional groups are bonded to the silica gel matrix, which can form hydrogen bonds with the hydroxyl groups of the key component β - (1 → 3) - glucan in Poria cocos, resulting in specific retention behavior, separation from impurities, and reduced adsorption of monosaccharides, pigments, and other impurities, laying the foundation for quantitative analysis.
2、 Structural features: optimized design, adapted to detection needs
•High quality column materialMade of high-quality stainless steel, resistant to pressure and corrosion, suitable for various mobile phases, ensuring long-term stability and avoiding detection errors caused by column damage.
•Accurate particle size fillerSilicone particles undergo strict screening to achieve uniform particle size, ensuring stable sample flow, improving column efficiency, reducing peak broadening, and optimizing detection peak shape and accuracy.
•Reasonable size matchingBased on the characteristics of Poria cocos detection, optimize the column length and inner diameter, such as the common 4.6 × 250mm specification, taking into account the separation length and flow rate pressure balance, and adapting to most laboratory liquid chromatography instruments.
3、 Performance advantage: Comprehensive adaptation, ensuring precision
•Excellent separation degreeFacing complex Poria cocos samples, it can clearly separate the target peak and impurity peak of β - (1 → 3) - glucan, with a separation degree exceeding the requirement of ≥ 1.5 in the Chinese Pharmacopoeia, often reaching 3.0 or above, avoiding peak overlap.
•High column efficiency and optimal peak shapeThe theoretical plate count of the target peak is much higher than the pharmacopoeia standard of ≥ 1500, but it often exceeds 5000 in practice. The tailing factor meets the requirement of ≤ 1.5, which improves the accuracy of quantitative analysis.
•high sensitivityWhen detecting the reference substance, the peak height response is obvious and the system noise is low, which meets the quantitative requirements of trace components in Poria cocos and ensures accurate detection of trace active ingredients.
4、 Practical application: Multi scenario coverage, quality control
•Testing of medicinal herbs and decoction piecesAccurately determine the content of β - (1 → 3) - glucan, determine whether it meets the requirement of pharmacopoeia ≥ 50.0%, provide a basis for quality grading and authenticity identification of Poria cocos, and help enterprises control the quality of raw materials.
•Traditional Chinese patent medicines and simple preparations detection: In the complex traditional Chinese patent medicines and simple preparations formula, accurately identify the characteristic ingredients of Poria cocos, eliminate interference, detect the content of effective ingredients, and ensure the quality of traditional Chinese patent medicines and simple preparations is stable and the efficacy is consistent.
•Application in scientific research fieldTo provide reliable tools for optimizing the extraction process of active ingredients from Poria cocos and studying the effects of processing methods on ingredients, and to assist researchers in exploring the chemical composition and pharmacological mechanisms of Poria cocos.
Beijing Yinglaike COSMOSIL Poria cocos testing column plays a key role in various aspects of Poria cocos testing with excellent technology, optimized structure and stable performance, providing high-quality solutions for daily quality testing and cutting-edge scientific research, helping to improve the quality control level of Poria cocos and promote the healthy development of the traditional Chinese medicine industry.
