Abstract
Dalbergia sissoo Roxb., rich in isoflavones and isoflavone glycosides, is widely used to treat osteogenic effects, pain, and other diseases. This study employed simple procedures based on preparative reversed-phase high-pressure liquid chromatography (prep-RP-HPLC) for large-scale isolation of isoflavones and isoflavone glycosides present in Dalbergia sissoo leaves (DSL). The seven compounds were isolated from the ethanolic extract by the preparative HPLC–PDA method, and their purity was > 95%. The authors carried out an in silico analysis to find possible anti-aging compounds. Isolated compounds biochanin-A-7-O-[β-Dapiofuranosyl-(1–5)-β-D-apiofuranosyl-(1–6)-β-D-glucopyranoside (DS2) and biochanin-A-7-O [β-D-apiofuranosyl-(1–6)-β-D-glycopyranoside (DS3) demonstrated docking scores of −10.466 and −9.430 with docking energies of -81.864 and -77.531 kcal/mol, respectively, to the Hyaluronidase enzyme. For the Collagenase enzyme, they showed docking scores of −10.734 and −10.777 with docking energies of −107.102 and −98.317 kcal/mol, respectively. Against the Tyrosinase enzyme, Compounds DS2 and DS3 had docking scores of −7.333 and −7.993 with docking energies of −59.933 and −84.825 kcal/mol, respectively. For the elastase enzyme, they exhibited docking scores of −9.840 and −7.993 with docking energies of −68.490 and −84.815 kcal/mol, respectively. This study found that the isolation and purification method is simple and produces neat chromatograms with good selectivity and reproducibility. At the same time, docking results revealed that the compounds exhibited anti-aging properties.
期刊介绍:
Separation sciences, in all their various forms such as chromatography, field-flow fractionation, and electrophoresis, provide some of the most powerful techniques in analytical chemistry and are applied within a number of important application areas, including archaeology, biotechnology, clinical, environmental, food, medical, petroleum, pharmaceutical, polymer and biopolymer research. Beyond serving analytical purposes, separation techniques are also used for preparative and process-scale applications. The scope and power of separation sciences is significantly extended by combination with spectroscopic detection methods (e.g., laser-based approaches, nuclear-magnetic resonance, Raman, chemiluminescence) and particularly, mass spectrometry, to create hyphenated techniques. In addition to exciting new developments in chromatography, such as ultra high-pressure systems, multidimensional separations, and high-temperature approaches, there have also been great advances in hybrid methods combining chromatography and electro-based separations, especially on the micro- and nanoscale. Integrated biological procedures (e.g., enzymatic, immunological, receptor-based assays) can also be part of the overall analytical process.
