The immunostimulating activities of anti-tumor Polysaccharides from Pseudostellaria heterophylla
Immunopharmacology, 1994We have previously shown that a mitogenic fraction (PH-I) separated from Pseudostellaria heterophylla exhibits both immunomodulatory and anti-tumor activities. 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-I C) were assessed for their anti-tumor activity in vivo.

[Rapid molecular identification of pseudostellariae radix].
Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2015To establish a convenient and rapid method for identification of Pseudostellariae Radix by molecular identification, the rDNA-ITS sequences of Pseudostella riaheterophylla and its adulterants had been aligned to find out specific fragment. The specific primers against the fragment were designed and the PCR amplification conditions were optimized.

Maxent model was applied in the study to filtering the climate factors layer by layer. Polysaccharides and pseudostellarin B the two internal quality evaluation index were combined to analyse the interlinkages between climate factors and chemical constituents in order to search for the critical climate factors of Pseudostellaria heterophylla.

Cloning and analyzing a squalene synthase gene in Pseudostellaria heterophylla
Gene Reports, 2018Abstract 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.

[Chemical constituents from roots Pseudostellaria heterophylla].
Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2008To 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-

Simulating the process of traditional Chinese medicine decoction, Radix Pseudostellariae protein (RPP)-based nanoparticles were constructed by combining heat treatment with pH adjustment in succession. The formed nanoparticles were characterized as homogeneously dispersed sphere within 100 nm in diameter.
