Cyclopeptides and Amides from Pseudostellaria heterophylla (Caryophyllaceae)

Helvetica Chimica Acta, 2003
AbstractFrom the roots of Pseudostellaria heterophylla, three cyclopeptides and three amides were isolated, besides heterophyllin A and B. Their structures were determined as cyclo (Ala‐Gly‐Pro‐Val‐Tyr‐) (heterophyllin J; 1), cyclo (Ala‐Gly‐Pro‐Tyr‐Leu‐) (pseudostellarin A; 2), cyclo (Gly‐Gly‐Gly‐Pro‐Pro‐Phe‐Gly‐Ile‐) (pseudostellarin B; 3), methyl γ ...

[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 ...

Research on quality regionalization of cultivated Pseudostellaria heterophylla based on climate factors

China Journal of Chinese Materia Medica, 2016
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.

Transcriptomic analysis of Pseudostellariae Radix from different fields using RNA-seq

Gene, 2016
Pseudostellariae Radix is an important traditional Chinese medicine (TCM), which is consumed commonly for its positive health effects. However, a lack of transcriptomic and genomic information hinders research on Pseudostellariae Radix. Here, high-throughput RNA sequencing (RNA-seq) was employed for the de novo assembly to analyze the transcriptome in ...

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.
