 note = {A flatoxins are extremely harmful and are the most carcinogenic substances known in nature, and as such, affect rice quality to a great extent. This study was undertaken to examine the presence of aflatoxigenic fungi in ten samples of long grain rice obtained from various provinces in Thailand. The rice grains were investigated directly for fungal colonization   on agar plates. The major fungal genera detected were Eurotium Syncephalastrum, and Aspergillus Several isolates of Aspergillus flavus, a well-known aflatoxigenic species, were obtained from four rice samples. Aflatoxin production was confirmed in seven isolates using a  HPLC 日uorescence detection method. In all isolates, more than 1,000 ng/g of aflatoxin B1 was detected, with 10-30 ng/g of aflatoxin B2 also being detected, whereas aflatoxin G1 and aflatoxin G2 were under the limit of detection., アフラトキシンは有害かつ最も発がん性の高い天然物で、コメの甚大な品質低下を招きうる。タイの各地方から入手した長粒種の穀粒サンプル 10 点で、アフラトキシン産生菌の調査を行った。コメ穀粒を直接、寒天平板培地に置いて調査した。主な検出菌は Eurotium 属、Syncephalastrum 属、Aspergillus 属であった。アフラトキシン産生で知られる Aspergillus flavus が、 4 点の試料より数株得られた。HPLC- 蛍光検出法によって、7 菌株のアフラトキシン産生能を確認した。全ての菌株で 1,000 ng/g 以上のアフラトキシン B1と10-30 ng/gのアフキシン B2が検出された。いっぽうアフラトキシン G１とアフラトキシン G2は、検出限界未満であった。},
