Title Untargeted metabolome analysis of foods using LC-MS (11) / LC-MSによる食品のノンターゲットメタボローム解析 (11)
Description Untargeted metabolome analyses of foods were performed using LC-MS. Food items were selected from the Standard Tables of Food Composition in Japan-2005 (Seventh Revised Version) published by the Ministry of Education, Culture, Sports, Science and Technology, Japan (hereafter, refered to as the standard table). Metabolites in foods were extracted with methanol, separated by reversed-phase LC and detected using a high-resolution mass spectrometry (LTQ-FT, ThermoFisher Scientific). Two different conditions (Method 1, and Method 5) were applied to ESI positive mode detections, and Method 1 was applied to ESI negative mode detection. A series of different parameter settings for PowerGetBatch software were used for peak detection, and valid peaks were selected by an alignment of the resulted peaks with those detected from several mock samples. The detailed peak information including the results from compound database search and prediction of flavonoid aglycones using FlavonoidSearch were published from the Food Metabolome Repository (

The IDs mean as follows:

Sample ID: Prefix "S" + Food Item No. in the standard table + blanch No.

∗ The basic blanch No. is 1, and larger numbers were assigned for different types of the food items, and so on.

M01: Method 1 for accurate mass measurement in ESI positive mode

M11: Method 1 for accurate mass measurement in ESI negative mode

M05: Method 5 for acquire MS3 spectrum in ESI positive mode

M90, M91: Pseudo analysis representing a set of analyses used in the alignment for each positive and negative analysis, respectively


LC-MSを用いて食品をノンターゲットメタボローム分析した。食品は、日本食品標準成分表2015年版(七訂)(文部科学省)(以後「食品成分表」)から代表的なものを選んだ。メタノール抽出後、逆相HPLCで分離し、高分解能フーリエ変換型質量分析(LTQ-FT, ThermoFisher Scientific)による分析を行った。一つの食品につき、二つの異なる条件(Method 1, Method 5)でESIポジティブ分析を行い、精密質量値とMS2、MS3スペクトルを得た。ESIネガティブ分析は、1つの条件で精密質量値とMS2スペクトルを得た。ピーク検出は、PowerGetBatchソフトの異なるパラメーター設定による複数回の検出結果をアラインメントし、同時にアラインメントした試料の代わりに水を用いたMock分析データを差し引くことで実施した。検出されたピーク情報から、データベース検索、FlavonoidSearchによるフラボノイドアグリコンの推定を行った結果は、食品メタボロームレポジトリ( )から公開している。
