“…Sesquiterpene pyridine alkaloids are a large group of highly oxygenated sesquiterpenoids that are predominantly isolated from the plants of the family Celastraceae. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] These alkaloids have attracted attention in various fields of medicine because of their significant biological activities, such as immunosuppressive, [5,15] insect antifeedant, insecticidal, [9,16] anti-HIV, [6,11,12] antitumour [1,2,17] and antiplasmodial. [13] Their potential application requires the development of a method for the reliable, fast, and low-cost analysis of this class of compounds.…”
