Analytical method development and validation for monosaccharide profiling in Lignosus rhinocerotis using rP-HPLC.
Lignosus rhinocerotis is rich in polysaccharide with diverse -bioactivities. This study developed a pre-column derivatization reversed-phase high-performance liquid chromatography (RP-HPLC) method for analyzing monosaccharides in Lignosus rhinocerotis polysaccharides (LRP). LRP underwent hydrolysis, derivatization, and separation on a Cosmosil 5C18-MS-II column at 254 nm. Baseline separation of eight standard monosaccharides was achieved within 45 min. Calibration curves, precision, and accuracy were validated. Quantitative analysis revealed LRP as a heteropolysaccharide containing mannose, ribose, rhamnose, glucose, galactose, xylose, and arabinose, with 100.28-111.02% recovery. This optimized RP-HPLC offers a simple, reproducible, and accurate tool for LRP monosaccharides analysis, facilitating in understanding its structure-function relationship.
期刊介绍：
The Journal of Asian Natural Products Research (JANPR) publishes chemical and pharmaceutical studies in the English language in the field of natural product research on Asian ethnic medicine. The journal publishes work from scientists in Asian countries, e.g. China, Japan, Korea and India, including contributions from other countries concerning natural products of Asia. The journal is chemistry-orientated. Major fields covered are: isolation and structural elucidation of natural constituents (including those for non-medical uses), synthesis and transformation (including biosynthesis and biotransformation) of natural products, pharmacognosy, and allied topics. Biological evaluation of crude extracts are acceptable only as supporting data for pure isolates with well-characterized structures.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymized refereeing by at least two expert referees.
