Qilian ocean originated from the rift of the late Proterozoic Rodinia continent(Pangea\|850), evolved through rift basin and became an archipelagic ocean in the Caledonian stage.

The “Huangyuan Movement" (in South Qilian and Central Qilian) and "Alashan Movement" (in North Qilian) in the latest Late Proterozoic formed a regional unconformity. The middle Proterozoic in the area are mudstones and carbonate rocks with stromatolites and ooids. The Qingbaikou System of the upper Proterozoic in the North Qilian and Corridor region is also mudstone and carbonate rock with stromatolites. The Qingbaikou System in Central Qilian is sandstones and mudstones. There are alkaline and tholeiite in the Sinian System in North Qilian and Corridor.

There are adult dose criteria for Chinese herbs in decoction in the Pharmacopoeia of the People＇s Republic of China （2010 Edition） at present. But Chinese herbs have been frequently used in much higher doses than the dose criteria. This study has been conducted to test the dependability of the dose criteria. METHODS： Twenty Chinese herbs were selected as representatives and their adult doses in decoction in Bei Ji Qian .lin Yao Fang, a famous ancient litera- ture, have been reviewed and compared with those in the Pharmacopoeia of the People＇s Republic of China （2010 Edition）. RESULTS： The adult dose criteria for all these 20 Chinese herbs in the Pharmacopoeia of the People＇s Republic of China （2010 Edition） haven＇t covered those in Bei Ji Qian .fin Yao Fang. Furthermore, maxi- mal adult doses in the dose criteria are much lower than those in Bei Ji Qian Jin Yao Fang. CONCLUSION： The dose criteria in the Pharmaco- poeia of the People＇s Republic of China （2010 Edition） are not comprehensive enough. Studying ancient literatures is an effective method to gain preciousChinese herbs＇ dose data and helps for new dose criteria＇s establishment in the future.展开更多
