A high-performance method for quantitation of aflatoxins B1, B2, G1, G2: Full validation for raisin, peanut matrices, and survey of related products at Ho Chi Minh City.

Optimization and validation for simultaneous quantitation of four aflatoxins B1, B2, G1, and G2 in peanuts and raisins were performed on ultra-performance liquid chromatography in a combination of fluorescence detector, without derivatization. The advantages were short analysis time, simple sample handling, and reduced solvent consumption. Instrument detection limits of AFB1, AFB2, AFG1, and AFG2 were 0.

Chemical composition and antibacterial activities of essential oils from rhizomes and aerial parts of (Araceae).

In this study, the phytochemical composition and antibacterial activity of the essential oils isolated from the rhizomes and the aerial parts of were analysed for the first time using gas chromatography-mass spectrometry (GC-MS) and disk diffusion method. Consequently, 36 constituents were reported from rhizomes, including linalool (57.4%), terpinen-4-ol (10.
