Sok-den (Phlomis umbrosa Turcz.) is a perennial herb in Labiatae plants. Shanzhiside methyl ester was isolated from BuOH Ex. of this plant. It was obtained as amorphous powder and its molecular formula is C_(17)H_(26)O<sub>11</sub>. Its structure was determined by chemical reactions an spectral analysis and compared with authentic sample of pentaacetate.

This paper presents a novel single-step method to prepare the Ag nanometallic particle dispersed fluid (nanofluid) by electrical explosion of wire in liquid, deionized water (DI water). X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM) and transmission electron microscope (TEM) were used to investigate the characteristics of the Ag nanofluids. Zeta potential was also used to measure the dispersion properties of the as-prepared Ag nanofluid. Pure Ag phase was detected in the nanofluids using water. FE-SEM analysis shows that the size of the particles formed in DI water was about 88 nm and Zeta potential value was about -43.68 without any physical and chemical treatments. Thermal conductivity of the as-prepared Ag particle dispersed nanofluid shows much higher value than that of pure DI water.
