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.

Pollen morphology of Chinese Pseudostellaria (Caryophyllaceae) and its systematic significance

Microscopy Research and Technique, 2020
AbstractUsing light and scanning electron microscopy, we studied the pollen morphology of six species (one of which are endemic) of Chinese Pseudostellaria. All species were studied for the first time. Results of this study indicated that pollen grains of Pseudostellaria are spheroidal or spheroidal‐polyhedral in shape and small or medium in size and ...

Fabrication of self-assembled Radix Pseudostellariae protein nanoparticles and the entrapment of curcumin

Food Chemistry, 2019
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.

Design and Analysis of the Excavation and Picking Equipment of Radix Pseudostellariae

2018
Radix pseudostellaria is widely cultivated because of its good pharmacology of traditional Chinese medicine. However, due to the lack of excavation device that suitable for digging operation in rolling foothills country, which leads to the low efficiency of harvesting of radix pseudostellaria in harvest season.
