基于化学计量学的多花黄精多糖部分酸水解产物PMP-HPLC指纹图谱构建

Construction of PMP-HPLC Fingerprint of Partial Acid Hydrolysate of Polygonatum cyrtonema Polysaccharides Based on the Chemometric Methods

  • 摘要: 本文通过构建多花黄精HPLC指纹图谱,结合多种化学计量学方法探讨不同产地多花黄精药材多糖的差异。采用1-苯基-3-甲基-5-吡唑啉酮柱前衍生化-HPLC法,建立多花黄精多糖类成分的指纹图谱,对其单糖组成、总多糖含量进行分析,并采用相似度评价(SA)、聚类分析(HCA)和主成分分析(PCA)方法,对多花黄精指纹图谱进行模式识别研究。结果显示,不同产地多花黄精均含有半乳糖醛酸,葡萄糖醛酸,半乳糖,葡萄糖和木糖;13批多花黄精药材相似度在0.781~0.945之间,总多糖含量为7.18%~16.27%,HCA和PCA将不同产地的多花黄精分为2类,采集于湖南省慈利县的样本单独为一支。以上研究结果表明多花黄精药材多糖指纹差异较大,为保障黄精药材临床用药的有效和安全,有必要建立多花黄精的规范化栽培技术体系。

     

    Abstract: In this paper, the polysaccharides fingerprints of Polygonatum cyrtonema Hua. were constructed, combined with various chemometric methods, to evaluate the differences of P. cyrtonema polysaccharides from different origins. The 1-pheny-3-methyl-5-pyrazolone (PMP) pre-column derivatization-HPLC method was applied to analyze the monosaccharide composition and total polysaccharide content of P. cyrtonema. Furthermore, the fingerprints were further evaluated by chemometric methods, including similarity analysis (SA), cluster analysis (HCA), and principal component analysis (PCA). The results showed that the composition of monosaccharides was galacturonic acid, glucuronic acid, galactose, glucose, and xylose. The similarities were ranged from 0.781 to 0.945. In addition, the content of total polysaccharides was in the range of 7.18% to 16.27%. HCA and PCA all divided P. cyrtonema polysaccharides from different origins into two categories, the samples collected in Cili County, Hunan Province were a separate one. These results indicated that the polysaccharide fingerprints of P. cyrtonema were quite different. Establishing the standardized cultivation technology system of P. cyrtonema is necessary to ensure clinical efficacy and safety.
