Determination of Pseudostellarin B in Pseudostellaria heterophylla by HPCE and Study on Its Fingerprints Analysis [PDF]
, 2007 建立了测定太子参中环肽Pseudostellarin B含量的高效毛细管电泳(HPCE)分析方法,对10种不同产地太子参中环肽Pseudostellarin B的含量进行了测定。HPCE工作条件:采用未涂层熔融石英毛细管(内径75μm,有效长度50cm),分离电压为15kV,柱温20℃,二极管阵列检测器(DAD)检测波长为203nm,缓冲液为20mmol/L硼砂(pH=9.3)溶液。在选定的工作条件下,环肽Pseudostellarin B浓度与其响应信号值之间具有较好的线性相关性(Y=0.6357X ...

Micro-Root Tuber Development and Histochemistry Study of Pseudostellaria heterophylla Miq. [PDF]
, 2009 采用植物组织培养、解剖学及组织化学定位方法研究太子参试管微块根发育的形态结构与营养物质积累特征的结果表明:太子参微块根由组培苗膨大的腋芽基部长出的不定根发育而成,经历了初生结构与次生结构发育,其膨大加粗是由于不定根的次生生长。维管形成层向内形成大量的次生木质部构成微块根的主要部分。淀粉粒是太子参微块根的主要营养存储方式。随着微块根的次生生长,淀粉粒先在次生木质部薄壁细胞中形成,随后在次生韧皮薄壁细胞中也大量积累。膨大的微块根可以合成太子参皂苷,成熟微块根中次生韧皮部的皂苷含量略高于次生木质部 ...
