High-speed counter-current chromatography (HSCCC) was applied to isolate and purify bioactive compounds in the essential oil of the rhizomes of Curcuma wenyujin. Two sesquiterpenes germacrone and curdione were successfully isolated and purified using two-phase solvent system composed of petroleum ether-ethanol-diethyl ether-water (5/4/0.5/1, v/v) in tail to head elution mode. 62 mg of germacron...

Plant density was varied with P, Ca, Mg, and KNO3 in a multifactor experiment to improve Curcuma longa L. micropropagation, biomass and microrhizome development in fed-batch liquid culture. The experiment had two paired D-optimal designs, testing sucrose fed-batch and nutrient sucrose fed-batch techniques. When sucrose became depleted, volume was restored to 5% m/v sucrose in 200 ml of modified...

The present study was designed to identify the chemical constituents of the methanolic extract of Curcuma longa L. rhizomes and their inhibitory effect on a hepatoma cell line. The methanolic extract was subjected to GC-MS analysis to identify the volatile constituents and the other part of the same extract was subjected to liquid column chromatographic separation to isolate curcumin. The inhib...

Antifungal activities of twenty four plant extracts and secondary metabolites of five Trichoderma strains were tested against conidial germination and germ tube growth of Colletotrichum capsici. Hundred percent inhibition of conidial germination and shortest germ tube formation of Colletotrichum capsici were recorded in Azadiracta indica (leaf), Ocimum sanctum (leaf) and Curcuma longa (rhizome)...

Biodegradable films with antioxidant properties have been studied in recent years. Curcumin is a polyphenol chemical obtained from turmeric extraction (Curcuma longa L.) with a range of biological activities. The objective this work was to determine diffusion coefficient of curcumin in the edible films based gelatin and yam-starch matrixes. The diffusion coefficient was determinate by Fluoresce...

Crude ethanolic extract and column chromatographic fractions of the Allepey cultivar of Curcuma longa Roxb, commonly called turmeric (tumeric) in commerce, were used as a stain for tissue sections. Staining was carried out under basic, acidic and neutral media conditions. Inorganic and organic dissolution solvents were used. The stain was used as a counterstain after alum and iron haematoxylins...

Spices have long been a part of human diets and commerce. Since the birth civilization, medicinal plants yielded wealth information on treating preventing illness. Still, growing understanding connection between nutrition health in food business has increased its relevance piqued researchers’ interest deciphering mechanisms action spices plethora beneficial properties attributed to them. Turmer...
