The growth year of ginseng is relevant to its quality and commercial value. Ginseng rhizome joint number increases by growth year. The relationship between the metabolite accumulation and the growth year of a rhizome remains unclear. Most forest-grown ginseng rhizomes can conveniently be separated into different joints and are suitable materials for investigating ginseng metabolite accumulation.
This work aims to elucidate how ginsenoside accumulates in the ginseng rhizome joint and if it is applicable for growth-year determination.
Forest-grown Panax ginseng rhizomes were separated into different joints according to their growth scars; ginsenosides in each joint were then tested using high-performance liquid chromatography-tandem mass spectrometry. The age-related ginsenosides screening was performed using orthogonal partial least squares analysis (OPLS). Several ground-cultivated ginseng rhizomes have also been tested.
Ginsenoside contents in different joints of a rhizome increase with its growth year and reach their corresponding equilibriums in specific years. Notoginsenoside R3 and ginsenoside Rg1 were the most relevant to the growth year. They increase continuously from 0 to 8 years. Perhaps, the OPLS improved the linearity of the relationship between scores and ages. The predictions of the growth year of a rhizome joint using the OPLS models were accurate.
Some ginsenosides increased in ginseng rhizome joints by their growth year. The OPLS score of a rhizome joint can be used to determine its growth year.
人参的生长年份与其品质和商业价值相关。人参根茎的节数随生长年份增加。根茎中代谢物积累与生长年份之间的关系尚不清楚。大多数林下参根茎可方便地分成不同的节，是研究人参代谢物积累的合适材料。
本研究旨在阐明人参皂苷在人参根茎节中的积累情况以及是否适用于生长年份的测定。
根据林下参根茎的生长疤痕将其分成不同的节；然后使用高效液相色谱-串联质谱法检测每个节中的人参皂苷。使用正交偏最小二乘法分析（OPLS）进行与年龄相关的人参皂苷筛选。还对几种园参根茎进行了检测。
根茎不同节中的人参皂苷含量随生长年份增加，并在特定年份达到相应的平衡。三七皂苷R3和人参皂苷Rg1与生长年份最为相关。它们从0到8年持续增加。或许，OPLS改善了得分与年龄之间关系的线性。使用OPLS模型对根茎节生长年份的预测是准确的。
人参根茎节中的一些人参皂苷随生长年份增加。根茎节的OPLS得分可用于确定其生长年份。
