で直接胃に投与した。そして、各ラットの頸静脈に埋め込んだカテーテルから、投与前と、投与後15、30分、1、2、4、8時間に0.4mL採血した。そして、代謝ケージに入れて、通常通り給餌し、24時間で再度0.4mLの採血を行った。また、ピセアタンノールおよびレスベラトロール投与後24時間に亘って、尿を採取した。なお、得られた血漿及び尿には、10分の1量の安定化剤(0.4% アスコルビン酸/0.02% EDTA/80 mmol/L リン酸ナトリウム、pH 3.6)を添加し、分析まで−30℃で保存した。

図1に、ラットに360μmol/kg体重のピセアタンノールを投与する前と投与後30分で採取した血漿の代表的なHPLCクロマトグラムを示す。投与前(A)は、ピークは検出されないが、ピセアタンノール投与後30分(B)では、ピセアタンノール、イソラポンチゲニン、及び複数のピセアタンノール代謝物のピークが検出され、ピセアタンノール投与後30分のサンプルを加水分解した場合(C)、ピセアタンノールとイソランポンチゲニンに加えて、ラポンチゲニンのピークが新たに現れる。一方、レスベラトロール投与後30分(D)、及びレスベラトロール投与後30分のサンプルを加水分解した場合(E)では、レスベラトロールのピークが検出されるが、ピセアタンノール、イソラポンチゲニン、及びラポンチゲニンのピークは検出されない。

以上のようにして、ラットにピセアタンノールを投与した時に、尿中に現れる代謝物を解析した。その結果、尿中のイソラポンチゲニンのピーク成分のマススペクトル(m/z 257)はイソラポンチゲニン標準製品と一致し、尿中のラポンチゲニンのピーク成分のマススペクトル(m/z 257)はラポンチゲニン標準製品と一致し、ピセアタンノールを投与したラットの尿中にイソラポンチゲニンおよびラポンチゲニンが検出されることが確認できた。
