Background. Herb-derived compound andrographolide sulfonate (called Xiyanping injection) recommended control measure for severe hand, foot, and mouth disease (HFMD) by the Ministry of Health (China) during the 2010 epidemic. However, there is a lack of good quality evidence directly comparing the efficacy of Andrographolide Sulfonate combination therapy with conventional therapy. Methods. 230 p...
the feasibility of extractive reaction of methacrylic acid from aqueous solution using a quaternary amine, tri–octyl methyl ammonium chloride (tomac) as an extractant, was studied. the diluents chosen in the present work belong to different chemical classes, n–butyl acetate, carbon tetrachloride, isoamyl alcohol, methyl isobutyl ketone, and toluene. the effect of initial acid concentration in t...
Construction of a hybrid strain which is capable of mineralizing components of a benzene, toluene, and p-xylene mixture simultaneously was attempted by redesigning the metabolic pathway of Pseudomonas putida. Genetic and biochemical analyses of the tod and the tol pathways revealed that dihydrodiols formed from benzene, toluene, and p-xylene by toluene dioxygenase in the tod pathway could be ch...
The title salt, C(5)H(6)N(+)·C(7)H(4)F(3)O(3)S(-), is an ion pair in which the pyridium cation is linked to the 4-(trifluoro-meth-yl)benzene-sulfonate anion by an N-H⋯O hydrogen bond. The F atoms of the trifluoro-methyl group are disordered over two sites in a 0.584 (9):0.416 (9) ratio.
The title compound, C(16)H(12)O(2), was synthesized from naphthalene-2,7-diol and prop-2-ynyl 4-methyl-benzene-sulfonate in the presence of sodium hydride. The crystal packing exhibits inter-molecular non-classical C-H⋯O hydrogen bonds and C-H⋯π inter-actions.

This study was intended to investigate the antioxidant activities of different solvent fractions (hexane (HEX), chloroform (CHL), ethylacetate (ETHYL) and methanol (MET) fractions) extract Andrographis paniculata GC-MS profiling most active fraction (MET). The crude fractionated using vacuum liquid chromatography method. Antioxidant activity evaluated total phenolic content (TPC), flavonoid (TF...
In the title compound, C(22)H(16)N(2)O(6)S(2), the dihedral angle formed by the mean planes of the two benzene rings of the 4-methyl-phenyl-sulfonate groups is 21.9 (1)° and these rings form dihedral angles of 48.26 (9) and 52.73 (9)° with the central benzene ring.
