Abstract
Imaging mass spectrometry (IMS) was conducted for the first time using ustalic acid (UA) and the fruiting body of Tricholoma kakishimeji to localize mushroom toxins. The mushroom materials were systematically collected in Japan, and analysis of the cross sections of the materials at a resolution of 120 μm using matrix-assisted laser desorption/ionization mass spectrometry (MALDI–IMS) revealed the localization of UA and its biogenically related metabolites. MALDI–IMS confirmed that UA was predominantly located on the entire surface of the fruiting body and accumulated in higher amounts in younger fruiting bodies than in mature ones. UA is the first toxic secondary metabolite in the genus Tricholoma locally identified using IMS in mushrooms.
期刊介绍：
The Journal of Natural Medicines is an international journal publishing original research in naturally occurring medicines and their related foods and cosmetics. It covers:
-chemistry of natural products
-biochemistry of medicinal plants
-pharmacology of natural products and herbs, including Kampo formulas and traditional herbs
-botanical anatomy
-cultivation of medicinal plants.
The journal accepts Original Papers, Notes, Rapid Communications and Natural Resource Letters. Reviews and Mini-Reviews are generally invited.
