RESUMEN

The fluoritum is used for gynecology frequently and it's for those diseases: kidney yang deficiency, Gong cold sterility, palpitation due to fright, insomnia and dreaminess and cold cough. It's ruled in Chinese Pharmacopoeia (1985 edition) that the fluoritum originates from fluorite which belongs to fluoride minerals. Its main content is CaF2. The colors are of differents grades with purple or green. In the market, there are large differences in quality and it has various colors. Besides of the ruled color of purple and green, white and yellow are also common colors. By digging into and analysis the relevant research literature of fluorite which belongs to fluoride minerals, colors and coloration mechanism of fluorite are summarized in this paper.Natural fluorite is the mineral which has the most species of colors in nature. The different colors of fluorite are mainly caused by the impurity elements. At present, there are mainly about the coloration mechanism of fluorite: rare earth ions (4fN ions), color center, inclusions, crystalline domains or sub microscopic inclusions. The green of fluorite is produced by 570 nm and 305 nm absorption peaks which are caused by Sm2+ and compensated ions Na+ centers generated color center. The yellow of fluorite is produced by the joining of transition element, resulting in the formation of charge transfer between the crystal ions and the formation of O2-O32- ion molecule.The black of fluorite, mainly was attributed to the existence of a higher degree of evolution of organic matter. In this passage,suggestions for modification of the properties of fluoritum in Chinese Pharmacopoeia are put forward.

RESUMEN

An efficient and rapid synthesis of novel anti-inflammatory and antimicrobial agents using 4-aminoantipyrine, nicotinic acid, ethylisocyanoacetate and substituted aldehydes via Ugi four component reaction (Ugi-4CR) protocol under microwave irradiation in presence of Fluorite as an efficient catalyst. The microwave synthesis route afforded better yields with shorter reaction time. The novel heterocycles were characterized on the basis of IR, 1H NMR and Mass spectral analysis. All the synthesized molecules 5 (a-h) were examined for their potential in-vivo Anti-inflammatory activity on Wistar Albino rats using a standard reference drug, Indometacin. The synthesized compounds were also screened for their potent in-vitro Antimicrobial activity using few Grampositive and Gram-negative bacteria against a reference antibiotic, Ampicillin and Streptomycin.
