The Citrus reticulata (orange) peels has been employed as adsorbents for removing inorganic and organic pollutants from wastewater extensively due to its low cost and eco-friendly nature. This research work concerns with the study of comparative removal of Indigo carmine dye from water using simple, formaldehyde and urea treated Citrus reticulata peels. The effect of adsorption parameters were investigated and maximum sorption capacity was obtained from Langmuir isotherm model at optimized conditions, i.e.: 5.90, 14.79 and 71.07 mg g-1 for simple, formaldehyde treated and urea treated Citrus reticulata peels, respectively. 

Feasibility of process is indicated by the values of separation factor, Gibb’s free energy and adsorption intensity ‘n’. The results of present study indicate that Citrus reticulata peels has inherited a lots of capacity for removing anthraquinone type of dyes, which can be further improved by treating with formaldehyde or urea in economical way.

Natural product based leads to fight against leishmaniasis

image

The growing incidence of parasitic resistance against generic pentavalent antimonials, specifically for visceral disease in Indian subcontinent, is a serious issue in Leishmania control. Notwithstanding the two treatment alternatives, that is amphotericin B and miltefosine are being effectively used but their high cost and therapeutic complications limit their use in endemic areas. In the absence of a vaccine candidate, identification, and characterization of novel drugs and targets is a major requirement of leishmanial research. This review describes current drug regimens, putative drug targets, numerous natural products that have shown promising antileishmanial activity alongwith some key issues and strategies for future research to control leishmaniasis worldwide
