[Objective] To determine the contents of three major tanshinones in Salviae miltiorrhizae health tea by HPLC.[Method] The HPLC conditions were as follows:Insertsil ODS-SP column(4.6 mm×250 mm,5 μm),mobile phase of acetonitrile-water(V:V=62:38),detection wavelength of 270 nm,flow rate of 1.0 ml/min,sampling amount of 15 μl and column temperature of 30 ℃.[Result] Three compositions of tanshinones were well-separated and the average recovery of cryptotanshinone,tanshinone Ⅰ,tanshinone ⅡA were 98.2%,98.7% and 98.4% respectively(RSD of 1.20%,1.96% and 1.74%,n = 3).The content of the tanshinones in the sample were 1.19,0.79 and 2.25 mg/g respectively.[Conclusion] HPLC has the advantages of simple,rapid and reliable,which can be used to control the quality of Salviae miltiorrhizae health tea.

“没有先例:一次重塑香港录像和新媒体艺术叙述的尝试”(以下简称“没有先例”)由香港录映太奇呈现,于香港亚洲艺术周期间开幕。录映太奇成立于1986年,意在搭建一个展示另类媒介的平台。三十年来,伴随录像、新媒体和互联网的迅猛发展,录映太奇终于成长为香港成熟的新兴艺术的土壤,它在资本市场中独善其身,为本地新艺术提供了机遇。  展览“没有先例”试图做一次彻底的回溯与重构。香港当代艺术的肇始与录像艺术有着深
面对光怪陆离、参差各异的当代艺术圈,面对让人眼花缭乱、哑然失声的当代艺术作品,我们不禁要问,难道人类已经真的走到了阿瑟丹托所谓的“艺术终结之后”的后艺术时代7难道艺术已经完全脱胎换骨,并已经绝弃了与过往的一切联系?难道艺术史叙事已经完全告别格林伯格专注于媒介形式的现代主义逻辑,抛弃了任何诉诸审美经验的描述?假如真的如此,那么当代艺术是否在1917年——杜尚的小便器《泉》诞生时——便已经开始了呢?那
