Flonicamid and dinotefuran are highly effective insecticides in paddy but residue persistence in crop and transmission into food and feed is unknown. This study aimed to examine initial deposits and dissipation kinetics of flonicamid and dinotefuran in paddy matrices and processed products including bran oil. The method was validated following acetonitrile extraction, dispersive solid phase clean-up and finally determination using liquid chromatography-mass spectrometry/mass spectrometry.

- Indian cardamom, primarily grown in southern India at altitudes between 900 and 1400 meters, has been analyzed for its essential oil composition using gas chromatography-mass spectrometry (GC-MS).
- The study found significant levels of the major monoterpene 1, 8-Cineole, with concentrations between 28.94% and 34.91% in various cardamom varieties, along with other important monoterpenes.
- Additionally, the research identified sesquiterpenes and ester constituents, highlighting α-Terpinyl acetate as the most prominent ester in one variety, marking the first detailed report on the phytochemical profiles of recent Indian cardamom varieties.
