摘要
作者用薄层层析法对荷叶、鲜荷叶汁、莲子心所含成分进行比较 ,并以芦丁、槲皮素等降脂成分作定性对照 ,结果荷叶、莲子心具有很多相同成分 ,表明荷叶。
The author made layer dissection analysis on the contents of lotus leaf and its extract, embryo and made comparison among them and contrast between them and serum-lowering herbs such as eldrin and cortex querci dentatea in qualified-oriented study. We found that lotus leaf and lotus embryo have many identical element which shows that they both have higher exploration value as a Chinese medicine. Key words: lotus leaf, lotus embryo layer dissection analysisBZ]Tin oxide ultrafine powders used as transparent conducitive films and conductive paints have extensive application prospects. Antimony-doped tin oxide ultrafine powders in size of nanometers were prepared by chemical coprecipitation using SnCl 4·5H 2O and SbCl 3 as precursors.The characteristics of the powders were investigated gy differential scanning calarmeutry and thermogravimentric analysis (DSC-TG),X-ray diffraction (XRD),transmission electron microscope (TEM) and ultraviolet spectrum analysis(UV).The influences of heating temperature and heating time on the particles size and powders resistance were researched.The reason of the powders emerging light blue was also derived.
