[Analysis and evaluation on Paeoniae Radix Alba from different cultivars by UPLC-Q-TOF-MS and HPLC].

In this study, an established ultra-high performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) method was combined with multivariate statistical analysis to investigate the commonality and difference of main chemical components in the medicinal parts of Paeonia lactiflora from different cultivars; in addition, a high performance liquid chromatography(HPLC) method was established to simultaneously determine the content of eight active components in Paeoniae Radix Alba. Non-targeted analysis was carried out by UPLC-Q-TOF-MS on a Waters ACQUITY UPLC BEH C_(18)(2.1 mm×100 mm, 1.

[Multiplex PCR method for simultaneous identification of Xanthii Fructus and its adulterants].

The purpose of this study is to establish a molecular method to identify Xanthii Fructus and two adulterants, the fruits of Xanthium mongolicum and X. italicum. Xanthii Fructus is the fruit of X.

Cloning and Functional Characterization of Two Germacrene A Oxidases Isolated from .

Sesquiterpene lactones (STLs) from the cocklebur exhibit significant anti-tumor activity. Although germacrene A oxidase (GAO), which catalyzes the production of Germacrene A acid (GAA) from germacrene A, an important precursor of germacrene-type STLs, has been reported, the remaining GAOs corresponding to various STLs' biosynthesis pathways remain unidentified. In this study, 68,199 unigenes were studied in a de novo transcriptome assembly of fruits.

Single crystal growth and physical properties of layered compound SrCdBi.

We have grown the high quality single crystals of SrCdBisuccessfully and investigated the physical properties systematically through measurements of magnetoresistance (MR), Hall effect, magnetic susceptibility, and specific heat measurements. The compound is a nonmagnetic 112-type pnictide with a Bi square net layer, which is potential for hosting Dirac fermions. We found that it exhibited metallic behavior with an anomaly appearing at around 210 K.

A rapid reduction of Au(I→0) strategy for the colorimetric detection and discrimination of proteins.

A gold nanoparticle (AuNP)-based sensing strategy based on rapid reduction of Au(I→0) is proposed. As a proof-of-concept study, the proposed sensing principle is designed for simultaneous and colorimetric detection and discrimination of multiple proteins. In the presence of HO, the target proteins could reduce Au(I) (i.

Magnetic and magneto-transport studies of two-dimensional ferromagnetic compound FeGeTe.

We have systematically reported the magnetic and magneto-transport properties of two-dimensional itinerant ferromagnetic compound FeGeTeat high magnetic fields of 58 T and demonstrated the correlation between its transport and magnetism. Anomalous two-steps magnetic ordering and antiferromagnetic-like transitions in zero field-cooling (ZFC) curves for∥-plane are observed. Additionally, we find that intrinsic negative magnetoresistances in bulk FeGeTesingle crystal are mainly attributed to the suppression of spin-fluctuations in low magnetic fields.

[Next generation sequencing and transcriptome analysis of root bark from Paeonia suffruticosa cv. Feng Dan].

Moutan Cortex is an important traditional Chinese medicine, "Fengdan Pi" was known as Dao-di herbs from the root bark of Paeonia suffruticosa cv. Feng Dan for its extracted various active components. However, the genetic basis for their activity is virtually unknown.
