Rhodiola sachalinensis is an endangered species with important medicinal value. We used inter-simple sequence repeat (ISSR) and methylation-sensitive amplified polymorphism (MSAP) markers to analyze genetic and epigenetic differentiation in different populations of R. sachalinensis, including three natural populations and an ex situ population. Chromatographic fingerprint was used to reveal HPL...

t-2 toxin is the most poisonous trichothecene produced by fusarium species especially f.sporotrichioides . t-2 toxin is a biological contaminant in a number of agricultural commodities that can cause severe diseases among humans and animals and even lead to death. the aim of the current study is the analysis of t-2 mycotoxin in fusarium species by high-performance liquid chromatography (hplc) c...

was performed in both direct analysis of MSB and analysis of MN by converting MSB to MN with sodium carbonate. GC-FID method was carried out on the HP-5 capillary column GC-FID and HPLC-DAD methods were developed for determination of menadione (MN) and menadione sodium bisulphite (MSB). By means of each method, quantitative analysis of MSB in commercial pharmaceutical using nitrogen gas. HPLC-D...

In the biological sciences, mass spectrometry is one of the most popular methods employed for the determination of the molecular weights and structures of metabolites. The popularity of mass spectrometry is due to the high sensitivity of the analytical method and the possibility of obtaining molecular weights and structure of metabolites directly from high performance liquid chromatography (HPL...

Pharmaceutical analysis based on chromatographic separation is an important part of studies aimed at developing routine quality analysis of drugs. High-performance liquid chromatography (HPLC) is one of the main analytical techniques recommended for drug analysis. Although it meets many criteria vital for analysis, it is time-consuming and uses a relatively high amount of organic solvents compa...

Non-targeted strategies based on high-performance liquid chromatography with ultraviolet detection (HPLC-UV) and fluorescence (HPLC-FLD) fingerprints were evaluated to accomplish the classification authentication of instant coffee (40 samples), decaf (26 chicory (22 samples, including both ground instant), as well detect quantify frauds adulteration by multivariate chemometric methods. HPLC-UV ...
