T/FDSA 0081-2025 Determination of Aflatoxin Content in Chinese Medicinal Materials by Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS)
Basic Information
Scope
Scope: This document describes the determination method of aflatoxin B1, aflatoxin B2, aflatoxin G1, and aflatoxin G2 (hereinafter referred to as AFT B1, AFT B2, AFT G1, and AFT G2) in traditional Chinese medicines. This document is applicable to the determination of AFT B1, AFT B2, AFT G1, and AFT G2 in animal and plant-based traditional Chinese medicines such as cinnamon bark, cassia seeds, dried tangerine peel, lotus seeds, coix seed, earthworm, moth caterpillar, horse chestnut, cicada shell, pine resin, angelica, etc. Main technical contents: 5.
