采用反相高效液相色谱法系统地对人参芦头、主根的木栓部、韧皮部和木质部、参须等部位进行了分离分析,并利用主成分分析对HPLC数据进行了分类研究,探索了人参根不同部位和不同位点的差异性。从木栓部、韧皮部至木质部人参皂苷和其它组分峰高不断降低,芦头和参须组分和峰高与木栓部类似;木栓部、韧皮部和木质部不同位点组分和含量大致是芦头到须根逐渐减少;木栓部和木质部组成有差异性,韧皮部数据落在两者之间。本研究通过高效液相色谱和主成分分析清晰的揭示了人参根不同部位和不同位点的规律性和差异性。
RP-HPLC was used to systematically separate and analyze the cork, phloem and xylem, ginseng and other parts of ginseng root, main root, and ginseng. The principal component analysis was used to classify the HPLC data, and the ginseng Differences in different parts of the root and different loci. From the cork, phloem to the xylem ginsenosides and other components continuously reduce the peak height, the Ash content and parameter and component of the peak height and cork similar; cork, phloem and xylem different site components and content of roughly Is the head to the fibrous roots gradually reduced; cambium and xylem composition is different, phloem data fall between the two. In this study, the regularity and difference of different parts and sites of ginseng root were clearly revealed by HPLC and principal component analysis.
