Pesticidal Activity of Sundarban Mangrove Plant Extracts against Sitophilus Pests and Identification of Active Constituents Using LC-MS by Md. Abdur Rahman, Rinku Rani Paul, Chaina Biswas, Hakima Akter, Razina Rouf, Sushmita Nath, Jamil A. Shilpi, Lutfun Nahar, Stayajit D. Sarker, Shaikh Jamal Uddin

“…The active fraction of A. corniculatum was further profiled for identification of active compounds using LC-ESI-MS and identified (along with some unknown peaks) two previously reported compounds at m/z 625.17630 (isorhamnetin 3-O-rutinoside) and 422.25346 (paspaline) as major constituents. Insecticidal activities of these plants are reported in this study for the first time and would be useful in promoting research aiming for the development of new biopesticides from mangrove plants.…”
