[Chemical constituents from roots Pseudostellaria heterophylla].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2008
To study the chemical constituents of Pseudostellaria heterophylla.The compounds were isolated by silica gel and Sephadex LH-20 column chromatography and purified by recrystallization. Their structures were elucidated on the basis of physicochemical properties and spectral analysis.Seven compounds were identified as 2-minalin (1) , 3-furfuryl pyrrole-2-

Cloning and analyzing a squalene synthase gene in Pseudostellaria heterophylla

Gene Reports, 2018
Abstract Triterpene saponins are primary bioactive compounds in the tuberous roots of Pseudostellaria heterophylla, which is one of well-known traditional Chinese medicines. Squalene synthase (SQS) is the key speed-limiting enzyme of saponin biosynthesis pathway. Here, we cloned and analyzed a SQS gene in P. heterophylla.

[A research on fast-propagation of Pseudostellaria heterophylla].

Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2003
The result of fast-propagation of Pseudostellaria heterophylla by tissue culture showed that the best explant was stem tip. It also showed the suitable inducement mediums were MS + 6-BA 2.0 mg/L + NAA 0.2 mg/L or MS + 6-BA 4.0 mg/L + NAA 0.4 mg/L for the clustered bud, MS + 2,4-D 4.0 mg/L + Kt 0.5 mg/L or MS + 2,4-D 3.0 mg/L + Kt 0.5 mg/L for the ...

iTRAQ-based quantitative proteomic analysis of cultivated Pseudostellaria heterophylla and its wild-type

Journal of Proteomics, 2016
Pseudostellaria heterophylla is an important traditional Chinese herbal medicine with vast clinical consumption because of its positive effects. To date, changes in the metabolite composition of P. heterophylla have been well documented; however, the molecular differences between cultivated P. heterophylla and its wild-type are still unknown.

The Induction of Cytokine Gene Expression in Murine Peritoneal Macrophs by Pseudostellaria Heterophylla

Immunopharmacology and Immunotoxicology, 1994
We have previously shown that a mitogenic fraction (PH-I) separated from Pseudostellaria heterophylla (P. heterophylla) could act as a priming agent for the release of tumor necrosis factor-alpha (TNF-alpha) in mice. In the present study, PH-I was further purified by gel filtration chromatography and the resulting three fractions (PH-I A, PH-I B and PH-

[Anther development and sperm isolation of Pseudostellaria heterophylla (Miq.)].

Fen zi xi bao sheng wu xue bao = Journal of molecular cell biology, 2009
Anther wall is general and tapetum is glandular. The process of meiosis of microspore mother cells is simultaneous and the tetrads are tetrahedral. The mature pollen of Pseudostellaria heterophylla (Miq.) is tree-celled. There are 22-30 germ pores on the pollen wall.
