Soil Physical and Moisture Properties,corticosteroid derivatives of this type were prepared and their GLC properties studied. The derivatives that were investigated satisfied three basic criteria essential for successful GLC (1) easily prepared with a minimum of chemical manipulation; (2) reasonable stability during thin-layer purification, and (3) stability in subsequent GLC.作者: 愚笨 時間: 2025-3-22 10:02
