Studies on structural elucidation of delphinium alkaloids by using LC-ESI-MS technique.
Journal Title: JOURNAL OF ADVANCES IN CHEMISTRY - Year 2015, Vol 11, Issue 3
Abstract
A rapid,sensitive and specific liquid chromatography-electron spray-mass spectrometry (LC-ESI-MS) method to identify the different diester-diterpenoid and monoester type alkaloids from delphinium cashmerianum Collected from Sopi Kargil. Chromatographic separation were achieved on c-18 coloumn and peaks determined by mass spectrometry in positive and negative modes.The validated method led to tentative identification of eight alkaloids on the basis of their retention times and fragmentation patterns. Results showed that the positive mode response was much higher than the negative ion mode .chromatographic conditions were optimized to obtain high resolution and short run time.
