摘　　要：不同采收时间,同一基地、同一品种太子参不同部位的多糖、总皂苷和环肽B含量的变化趋势一致,且差异较显著,但其块根中各含量的积累均呈现出6月下旬和4月下旬较高的规律性变化。其中,块根中环肽B含量的变化趋势为:6月>4月>5月>3月;而多糖和总皂苷含量的变化趋势则为:6月>4月>3月>5月。茎叶中多糖和环肽B的含量在采收期(6月下旬)均最低,具体表现为:5月27日>5月11日>4月21日>3月24日>6月26日;总皂苷的含量则随着月份的推移而降低,3月24日的采收的茎叶总皂苷平均含量最大,约为0.78%,6月26日最小,仅为3月24日的34.6%。茎叶各有效成分含量所占的比重不小,其皂苷含量明显大于块根的含量。Different har vest time, the same base and species in different parts of Pseudostellaria heterophlla polysaccharides, total saponins and Pseudostellarin B content changed by the same trend, and there were significant differences between the same base. But the accumulation of effective medicinal ingredients content of heterophlla root by the end of June and April regularly. Among them, the changed trend of Pseudostellarin B content of heterophlla root was： June 〉 April 〉 may 〉 March; and the content of polysaccharides and total saponins changed along with the same trend： June 〉 April 〉 march 〉 may.The polysaccharide and Pseudostellarin B content of stem and leaf in the harvest time （late June） were the lowest, concrete embodied ： May 27th 〉 May list 〉 April 21st〉March 24th〉 June 26th; The total saponins content reduced over months, the average content on March 24th was about 0.75%, and total saponins content harvested on June 26th was minimum, only 34.6% of that on March 24th.The proportion of effective medicinal ingredients content of heterophlla stem and leaf were not small,and the total saponins content was significantlly greater than roots.
