An integrated strategy toward comprehensive characterization and quantification of multiple components from herbal medicine: An application study in Gelsemium elegans / 中草药·英文版

Objective: To develop a powerful integrated strategy based on liquid chromatography coupled with mass spectrometry (LC-MS) systems for the comprehensive characterization and quantification of multiple components of herbal medicines. Methods: Firstly, different mobile phase additives, analysis time, and MS acquisition modes were orthogonally tested with liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (LC-QTOF/MS) in order to detect as many components of Gelsemium elegans as possible with high peak intensity. Secondly, several data mining strategies, including database searching, diagnostic ion filtering and neutral loss filtering, were utilized to perform chemical profiling. Subsequently, this study focused on the quantification and validation of the performance of a liquid chromatography-triple mass spectrometry (LC-QqQ/MS) assay based on derivative multiple reaction monitoring (DeMRM). Results: A total of 147 components from G. elegans were characterized, among them 116 nontarget components were reported for the first time. A sensitive and reproducible LC-QqQ/MS method was successfully developed and validated for the simultaneous relative quantification of 41 components of G. elegans. This LC-QqQ/MS method was then applied to compare the contents of components in the roots, stems and leaves. Conclusion: The present integrated strategy would significantly contribute to chemical studies on herbal medicine, and its utility could be extended to other research fields, such as metabolomics, quality control, and pharmacokinetics.

Leucosceptroid B from glandular trichomes of Leucosceptrum canum reduces fat accumulation in Caenorhabditis elegans through suppressing unsaturated fatty acid biosynthesis / 中国天然药物

Obesity that is highly associated with numerous metabolic diseases has become a global health issue nowdays. Plant sesterterpenoids are an important group of natural products with great potential; thus, their bioactivities deserve extensive exploration. RNA-seq analysis indicated that leucosceptroid B, a sesterterpenoid previously discovered from the glandular trichomes of Leucosceptrum canum, significantly regulated the expression of 10 genes involved in lipid metabolism in Caenorhabditis elegans. Furthermore, leucosceptroid B was found to reduce fat storage, and downregulate the expression of two stearoyl-CoA desaturase (SCD) genes fat-6 and fat-7, and a fatty acid elongase gene elo-2 in wild-type C. elegans. In addition, leucosceptroid B significantly decreased fat accumulation in both fat-6 and fat-7 mutant worms but did not affect the fat storage of fat-6; fat-7 double mutant. These findings indicated that leucosceptroid B reduced fat storage depending on the downregulated expression of fat-6, fat-7 and elo-2 and thereby inhibiting the biosynthesis of the corresponding unsaturated fatty acid. These findings provide new insights into the development and utilization of plant sesterterpenoids as potential antilipemic agents.

Detection of fetal RASSF1A gene in maternal plasma for noninvasive prenatal diagnosis / 中国实验血液学杂志

The aim of this study was to investigate the feasibility of using RASSF1A gene as a universal fetal marker in maternal plasma. Two methods of circulating cell-free fetal DNA (cffDNA) extracted from maternal plasma were compared. The better one was chosen for extraction of cffDNA in the 20 pregnant samples. The SRY gene and the RASSF1A gene treated with methylation-sensitive restriction enzyme were amplificated by RT-PCR and the PCR system was optimized. The results showed that the SRY gene was found in 11 out of the 20 pregnant samples, which was consistent with the postnatal sex. Using the optimized PCR system, the specifically amplified fetal-associated methylated RASSF1A gene was found after treatment with BstUI in 18 of the 20 pregnant samples, while the 2 samples failed in detection. It is concluded that the methylated fetal-specific RASSF1A gene can be used as a universal fetal marker for the presence of cffDNA in maternal plasma without fetal gender restrictions. So, it can be used for noninvasive prenatal diagnosis.
