本計畫選擇常用的藥材黃耆及含有黃耆之方劑黃耆建中湯為研究對象，並設計飲片及將飲片以粉碎機粉碎後，依標準篩網進行過篩，分別取顆粒在4 mesh(孔徑4.75 mm)以上、10 mesh(孔徑1.7 mm)、20 mesh(孔徑0.85 mm)及20 mesh (孔徑0.85 mm)以下等不同粒度之顆粒，共五種處理，探討萃取率並開發高效液相層析法(HPLC)進行成分之比較，期對濃縮製劑製造時之藥材顆粒粒度能提供一較完整之參考資料。

This project is focus on Chinese herbal medicines which are Astragali Radixs and Huang-Gi-Jian-Zhong-Tang as research targets, and design the sliced medicinal herbs and after crushing the sliced medicinal herbs with the pulverizer, have sifted in accordance with the standard screen mesh. Fetch the particle of different particle sizes that in the above of 4 mesh (aperture 4.75 mm), 10 mesh (aperture 1.7 mm ), 20 mesh (aperture 0.85 mm ) and less 20 mesh (aperture 0.85 mm ) are following, etc., amounts to five kinds of treatment, is compared to probe into the extracting rate and develop the high-performance liquid chromatography (HPLC ) and go on, one can offer one more intact reference material to the thick particle size of crude drags particle that draws back the preparation while making.
