An assessment of the antihyperlipidemic ingredients of Qi Ge Decoction based on metabolomics combined with serum pharmacochemistry.

This study aims to explore the pharmacological substance basis of Qi Ge Decoction (QG) in antihyperlipidemia through a combination of metabolomics and serum pharmacochemistry. We used ultra-performance liquid chromatography quadrupole-time-of-flight/MS (UPLC Q-TOF/MS) to analyze and identify the chemical constituents of QG in vitro and in blood chemical components. The metabolomics technology was used to analyze serum biomarkers of QG in preventing and treating hyperlipidemia.

Comparative analysis and evaluation of wild and cultivated Radix Fici Simplicissimae using an UHPLC-Q-Orbitrap mass spectrometry-based metabolomics approach.

Radix Fici Simplicissimae (RFS) is widely studied, and is in demand for its value in medicines and food products, with increased scientific focus on its cultivation and breeding. We used ultra-high-performance liquid chromatography quadrupole-orbitrap mass spectrometry-based metabolomics to elucidate the similarities and differences in phytochemical compositions of wild Radix Fici Simplicissimae (WRFS) and cultivated Radix Fici Simplicissimae (CRFS). Untargeted metabolomic analysis was performed with multivariate statistical analysis and heat maps to identify the differences.

UPLC-Q-TOF/MS analysis of chemical components of single decoction and combined decoction of Qige decoction reveals the differences between various preparation processes.

The aim of this work was to explore the differences between various pharmaceutical processes in combined solutions of a single decoction (QGHBY) and a combined decoction (QGHJY) of Qi-Ge decoction from the perspective of chemical composition changes, so as to further guide the clinical application of drugs. A combined solution of a single decoction and a combined decoction of Astragali Radix, Puerariae Lobatae Radix and Citri Reticulatae Chachiensis Pericarpium was prepared with the same technological parameters. The chemical components of the two were detected and identified based on UPLC-Q-TOF/MS, and the different components were determined by principal component analysis.

CCl-Induced Liver Injury Was Ameliorated by Qi-Ge Decoction through the Antioxidant Pathway.

Qi-Ge decoction (QGD), which is derived from the Huangqi Gegen decoction, contains three traditional Chinese herbs: (Huangqi), (Gegen), and (Chenpi). Gastric mucosal damage caused by ethanol was prevented and alleviated by QGD. However, the role of QGD in protecting the liver from toxins has not been reported.

Nontargeted urine metabolomics analysis of the protective and therapeutic effects of Citri Reticulatae Chachiensis Pericarpium on high-fat feed-induced hyperlipidemia in rats.

In this study, we focused on studying the changes in urine metabolites in hyperlipidemic rats using ultra-performance liquid chromatography coupled with quadrupole time-of-fight mass spectrometry (UPLC-Q-TOF/MS) and metabolomics, as well as the effect of Citri Reticulatae Chachiensis Pericarpium (CRCP) on hyperlipidemia. These urine samples were examined by UPLC-Q-TOF/MS to obtain MS data. The MS data were analyzed by principal component analysis and partial least squares-discriminant analysis to identify the differential metabolites.

Discrimination of Citrus reticulata Blanco and Citrus reticulata 'Chachi' as well as the Citrus reticulata 'Chachi' within different storage years using ultra high performance liquid chromatography quadrupole/time-of-flight mass spectrometry based metabolomics approach.

Using ultra high performance liquid chromatography quadrupole/time-of-flight mass spectrometry (UPLC-QTOFMS) based metabolomics, we focused on developing a method for the comprehensive distinction between Citri Reticulatae Blanco Pericarpium(CRBP) and Citri Reticulatae Chachi Pericarpium (CRCP), as well as the CRCP within different storage years in this study. Through this, we hope to enhance Citri Reticulatae Pericarpium (CRP) Quality Control system. Using UNIFI software and an online database identified chemical components in the 3-30 years CRCP(40 batches) and CRBP (10 batches)samples, and multivariate statistical analysis methods and heat-map were applied to distinguish between CRCP and CRBP and CRCP in different storage years.

Neuroprotective Effects of β-Asarone Against 6-Hydroxy Dopamine-Induced Parkinsonism via JNK/Bcl-2/Beclin-1 Pathway.

β-asarone, a major component of Acorus tatarinowii Schott, has positive effects in neurodegeneration disease, however, its effect on the Parkinson's disease (PD) remains unclear. In this study, the effects of β-asarone on behavioral tests, neurotransmitters, tyrosine hydroxylase (TH), and α-synuclein (α-syn) were investigated in 6-hydroxydopamine (6-OHDA) induced rats. Furthermore, the JNK/Bcl-2/Beclin-1 autophagy pathway was also studied.

Dynamic of neurochemical alterations in striatum, hippocampus and cortex after the 6-OHDA mesostriatal lesion.

Immediate neurochemical alterations produced by 6-OHDA could explain the general toxic pattern in the central nervous system. However, no evidences describe the effects of 6-OHDA on early changes of neurotransmitters in rats' striatum, cortex and hippocampus. In our study, unilateral 6-OHDA injection into medial forebrain bundle (MFB) was used in rats, then five neurotransmitters were analyzed at 3, 6, 12, 24, 48 and 72 h, respectively.

[Investigate into of effective constituent transference of herba Ephedrae and cortex Magnoliae officinalis in preparation course of Shujin Kechuan capsule].

Objective: Investigate into transport rate and retention rate transference of principal effective constituent in Shujin Kechuang capsule, a new development Chinese patent medicine for theraphy asthma.

Method: HPLC was applied to analyze the content of ephedrine hydrochloride and honokiol and magnolol in crude drugs and 60% ethanol extracting solution and 25% concentrated solution,50% concentrated solution, 100% concentrated solution and finished product ( Shujin Kechuang capsule).

Result: The transport rate of ephedrine hydrochloride and honokiol and magnolol is 56.
