Abstract
Two injection solutions of quinine 79, 77 resp., years were analyzed using RP-HPLC. The conditions of separation were optimized.
The quinine content is decreased about 13% for 79-year-old sample and about 8% for 77-year-old sample, respectively. Quinotoxine has been found as the decomposition product.
The compounds were identified by MS 2, and the ESI fragmentation mechanisms of compounds found were proposed.
