Spermacoce princeae (K. Schum) has been used in the treatment of bacterial skin infections Uganda. Pharmacological studies revealed that extracts S. exhibited antibacterial, antioxidant, and sun protection potential. This study aimed at isolating identifying pure compounds from based on comprehensive analytical characterization by multiple techniques.The plant samples were extracted sequential maceration using n-hexane, ethyl acetate, methanol, distilled water. The isolated a combination...
The bark of trees contains an interesting mixture bioactive compounds, or so-called extractives. use supercritical carbon dioxide (sc-CO2) eliminates both the need for organic solvents as extractants and danger that solvent traces might compromise purity extracts. Unfortunately, complexity natural variability extracts' composition render any utilization attempts rather challenging. Thus, in order to implement exploitation concepts a meaningful way, appropriate analytical techniques...
Multistage fractionation of pine bark was performed using subcritical and supercritical CO2 at increasing pressures temperatures. In total, seven fractions were collected, which demonstrated different enrichments families compounds. particular, yielded 41% the total extract in unsaturated fatty acids represented most abundant family. The subsequent five steps increased recovery sterol esters, wax esters resin higher temperatures pressures, reaching 80% extractable mass. last step, ethanol as...
Ephedra herb extracts are being extensively investigated in terms of their antioxidative, antimicrobial and antiproliferative properties, with phenolic components the general carriers these bioactivities. Here we describe a comprehensive set analytical methods employed to determine characterize both antioxidative activity qualitative profile acids flavonoids present several species different geographical origin. Spectrophotometric were used total content, flavonoid content activity....
The novel guanidine-based ionic liquid [mTBNH][OAc], which is suitable for an environmentally friendly lyocell-like spinning process, exhibits both high natural and thermal stability, superior to that of IONCELL ILs.
The impact of totally chlorine-free (TCF) bleaching chemicals on the composition and behavior detrimental lipophilic wood extractives in a mixed hardwood sulfite pulp was studied to determine their potential for pitch control without need additional reagents. Toward this end, acetone extracts were analyzed with commonly used gas chromatography (GC) more sophisticated ultraperformance convergence (UPC2). During EO(P)–Z–P bleaching, highest decrease extractive content achieved after ozone (Z),...
Acid-sensitive ion channels (ASICs) are sodium partially permeable to Ca2+ ions, listed among putative targets in central nervous system (CNS) diseases which a pH modification occurs. We targeted novel compounds able modulate ASIC1 and reduce the progression of ischemic brain injury. rationally designed synthesized several diminazene-inspired diaryl mono- bis-guanyl hydrazones. A correlation between their predicted docking affinities for acidic pocket (AcP site) chicken inhibition homo-...
Abstract Wood extractives are known to cause problems during the production of pulp and paper impact their mechanical properties. In present work, we systematically explored whether minute residual amounts that reprecipitate on fiber surface in final stages pulping process would lower thermal resilience softwood Kraft pulp. Pulp samples subjected different extraction methods were characterized by means thermogravimetric analysis. The compound classes constituting respective extracts...
