采用UFLC-Q-TOF-MS/MS技术,在正离子模式下,根据各物质的质谱裂解规律,研究鉴定出盐酸克林霉素棕榈酸酯分散片中16种杂质,其中克林霉素九酸酯、克林霉素十酸酯、克林霉素十一酸酯、克林霉素十三酸酯为首次检到,本研究为其质量监控提供了实验依据。
Sixteen impurities in clindamycin palmitate hydrochloride dispersible tablets were identified according to their fragmentation patterns and characteristic fragment ions by UFLC-Q-TOF-MS/MS in a positive mode. Among them, clindamycin nonanoate, clindamycin decanoate, clindamycin monodecanoate, clindamycin tridecanoate were firstly detected. These results provided a basis for quality control of clindamycin palmitate hydrochloride dispersible tablets.
