Highlights

  • Ginseng saponins content increase more dramatically between year 1 and 4
  • Ginseng plants grown in tough environment content more ginsenosides
  • Roots size and shape have little effect on their ginsenosides concentration

看点

  • 花旗参生长一年到四年期间人参皂苷含量大有不同
  • 花旗参的生长环境的艰苦会导致人参皂苷含量的增加
  • 花旗参的大小和形状对于人参皂苷含量的影响微乎其微

Root Age

Some researches have observed that in cultivated ginseng roots, the total ginsenoside (the active components of ginseng roots) concentration in roots increases with plant age over the lifetime of which the ginseng is in the ground. The most pronounced increase (about two thirds) occurs with the ginsenosides Rb1, mRb1, and Re. Total ginsenoside content increases from about 3% in year 1 to about 8% in year 4; and then it increases very slowly thereafter.

According to my own experiences, another factor may influences the ginsenoside concentration in the roots is their environment where they grown. More the environment prompt to plant diseases, more the root has higher concentration of ginsenosides. Wisconsin ginseng’s individual ginsenoside Rb1 is about 2.5%, but I regularly find roots from some farmers at about 3% that grown up in tough environment. For comparison, the Rb1 in wild ginsengs are over 3.5%. So I strongly believe that ginseng root produces ginsenosides to protect itself against diseases because most of the ginsenosides are found in its skin. That helps to explain why wild ginseng has such high concentration versus its cousin for the same root age.

参龄

一些研究已表明人参总皂苷(花旗参的有效成分)含量会随着花旗参在土地里的生长时间而逐年增加,尤其是人参皂苷Rb1, Rg1, Re,从花旗参生长的第一年起,总皂苷的含量约为3%,到第四年后,总皂苷含量可达到约8%,然而在第四年之后的生长中,皂苷含量的增加则趋于缓慢。
据我个人经验推断,另外一个可能影响人参皂苷含量的因素则是花旗参的生长环境,如果生长环境不良易使花旗参感染病害,则花旗参自身会产生更多的人参皂苷来防御。威斯康辛花旗参所含的人参皂苷Rb1平均含量约为2.5%,但我曾经发现个别农夫所种植的参的Rb1含量可高达3%,而他们唯一的共同点则是生长的环境较为艰苦。再来了解一下野生花旗参,其Rb1平均含量均在3.5%以上,因此我更加鉴定的认为:花旗参在生长过程中所产生的人参皂苷,其主要目的是为了防御病害,因为大部分人参皂苷存在于花旗参的表皮上。此结论也有助于我们理解,为什么在相同的参龄条件下,野山参会比种植参含有更多的人参皂苷。

Root Size and Shape

No difference in total ginsenoside content of dried roots weight between 2 and 8 grams was observed in research trials. Roots smaller than 2 grams contain slightly more ginsenosides than larger roots. Believe it or not, the slender roots (ginseng fibers) contain the highest ginsenosides concentration.

Root shape (long, half short or short) was not found to affect either the individual or total ginsenoside concentration.

In conclusion, in ginsenoside concentration perspective, the big winner is the ginseng fibers. Order a free sample from us and check it out yourself!

花旗参的大小和形状

曾有研究表明,烘干后的花旗参,如果净含量在2g-8g之间,其人参皂苷含量没有明显差异。而净含量小于2g的花旗参则反而会有更高一些的人参皂苷含量,无论你信不信,参须才是含有人参皂苷含量最高的部分。
花旗参的形状(长枝,中长枝,短枝)对于人参皂苷单体或总皂苷含量都没有太大的影响。
总的来说,以人参皂苷含量来对比,参须才是最强者。

 

 

Thanks for reading and best wishes from Wisconsin!
