Shape-Controlled Synthesis and Related Growth Mechanism of Pb（OH）2 Nanorods by Solution-Phase Reaction

We present a simple method to synthesize Pb（OH）2 nanorods by solution-phase reaction. Rod-like lead hydroxide precipitates are obtained by mixing lead nitrate with a concentration of about 0.01 M and potassium hydroxide with concentration of about O.03 M in an aqueous solution. Sodium chloride as an additive is premixed with the lead nitrate aqueous solution. The presence of chloride ions in the precursor solution results in the rod-like morphology of lead hydroxide precipitates. The growth mechanism of the lead hydroxide nanorods is discussed.     

Advances in chromatographic analysis of ginsenosidesEI北大核心CSCD

Ginsenosides possess pharmacological activities such as anti-aging，cardiovascular protection，and improving immunity. However，the detection and analysis of ginsenosides commonly suffer from the problem of low sensitivity owing to the complex matrix and low content of ginsenosides. Chromatographic technology was often used to detect ginsenosides owing to the advantages of high accuracy，high sensitivity，good reproducibility and low sample consumption，etc. In this review，the application of chromatographic analysis technologies in ginsenosides detection was summarized. First of all，accuracy of test results for the ginsenosides can be effectively improved by using high performance liquid chromatography（HPLC）combined with various detectors. Secondly，the combination of HPLC with mass spectrometry can be utilized for qualitative and quantitative analysis of ginsenosides， as well as other fields， such as metabonomics， pharmacokinetics， intestinal microorganisms and quality control. Moreover，the application of gas chromatography in analysis of ginsenosides was reviewed. Briefly，with the continuous development of chromatographic technology，the degree of accuracy for ginsenosides detection was effectively improved，which is beneficial to realize the effective analysis of ginsenosides. © 2023, Youke Publishing Co., Ltd.
