Introduction with historical remarks,ivatization and degradation, was used to unravel the often complex structures of alkaloids. The structure elucidation of a well-known alkaloid, such as, for example, strychnine, took almost 140 years after its first isolation by Pelletier and Caventou in 1818.作者: 管理員 時(shí)間: 2025-3-23 12:44

Electrochemical Detection of Alkaloids in HPLC,High-performance liquid chromatography (HPLC) is a valuable tool in plant analysis, due to its high power of resolution and compatibility for the determination of nonvolatile and thermally labile compounds. Therefore HPLC has often been applied in the determination of alkaloids (Verpoorte et al. 1984; Popl et al. 1990).作者: 希望 時(shí)間: 2025-3-27 06:46 作者: contradict 時(shí)間: 2025-3-27 13:24
