Total saikosaponins Content material Accumulated in Bupleurum Distinct Tissues beneath 3 Levels of Nitrogen Fertilization Initially, this study exploited an HPLC technique for the simultaneous quantification of 3 saikosaponins: saikosaponin A, saikosaponin C and saikosaponin D. Simultaneously, we also measured the total content of saikosaponins in various Bupleurum tissues under the three levels of nitrogen fertilization. For the diverse nitrogen fertilization levels, the total saikosaponins show an analogous tendency and mostly accumulated in the flowers and also the roots. Moreover, the LN level decreased the total saikosaponins content in flowers and roots; having said that, at the HN level, flowers showed a important increase within the total saikosaponins content material, whilst the total content material in roots remained steady (Figure 2A). When the total saikosaponins content material was fixed, we compared saikosaponin A, saikosaponins C and saikosaponins D. We located that the percentage of saikosaponins A was decrease than that of saikosaponins C and saikosaponins D with no nitrogen. Nitrogen fertilizer promoted the content material of saikosaponin A, and its increment was accompanied by a reduce in saikosaponins C in aerial parts (flowers, key shoots and lateral shoots); nonetheless, it was accompanied by a lower in saikosaponins D in roots (Figure 2B).
