Description
被験者の皮膚角質層の採取物から調製した脂質試料を液体クロマトグラフ−質量分析法で分離検出し、その検出データを多段マスクロマトグラムで解析することにより、皮膚角質層に含まれる脂質分子の組成情報を求め、得られた脂質分子の組成情報から、前記関連づけに基づき、被験者の肌質を評価する肌質評価方法を提供する。
(1)皮膚角質層の採取
普通肌(経皮水分蒸散量が10μg/cm2/hr以下)、及び、乾燥肌(経皮水分蒸散量が30μg/cm2/hr以上)の被験者の前腕屈側部にテープを押し付け、角質層を剥離した。それぞれのテープを半分に切り分け、一方をセラミド分子の解析に供し、もう一方をタンパクの定量(BCA Protein Assay)に供した。
(1)で角質層を採取したテープに、N−heptadecanoyl−D−erythro−sphingosineを含むメタノールを加え、超音波を照射することにより脂質を抽出した。
(2)のメタノール抽出液を窒素気流下で乾固し、これにクロロホルム/メタノール=99.5/0.5(v/v)を加えて溶解し、固相抽出用シリカゲルカートリッジに適用した。クロロホルム/メタノール=99.5/0.5(v/v)を十分に適用した後、クロロホルム/メタノール=95/5(v/v)を適用し、その溶出液を得た。
この溶出液を窒素気流下で乾固した後、ヘキサン/イソプロパノール/ギ酸=95/5/0.1(v/v/v)を加えて溶解し、試料溶液とした。
(4−1)液体クロマトグラフ−質量分析装置
液体クロマトグラフと質量分析装置が一体になった分析システムとして、横河アナリティカルシステムズ社、アジレント 1100シリーズ LC/MSDを使用した。
カラム及び分離条件は次の通りとした。
分離カラム:ジーエルサイエンス社、Inertsil SIL 100A−3、1.5mmφ×150mm(3μm)
ガードカラム:ジーエルサイエンス社、Inertsil SIL 100A−3、1.5mmφ×10mm(3μm)
溶離液a:ヘキサン/イソプロパノール/ギ酸=95/5/0.1(v/v/v)
溶離液b:ヘキサン/イソプロパノール/50mmol/Lギ酸アンモニウム水溶液=25/65/10(v/v/v)
グラジエント条件:表1
次のイオン化促進液を使用した。
イオン化促進液:イソプロパノール/5mmol/Lギ酸アンモニウムメタノール溶液=50/50(v/v)
イオン化促進液流速:0.1mL/分
イオン化法:ESI
極性:正イオン
測定質量範囲:250〜1500
フラグメンター電圧:150V
Vcap電圧:3500V
ネブライザー圧力:20psig
乾燥ガス温度:300℃
乾燥ガス流量:8L/分
得られたデータを、保持時間とm/zとイオン強度の3軸を有する多段マスクロマトグラムに展開した。その後、保持時間とm/zの情報からなるセラミド分子のデータベースを利用して各ピークを同定した。そして、各セラミド分子のピーク面積を求め、内部標準物質に対するピーク面積比を算出し、さらにタンパク量で除することにより、単位タンパク量当たりの各セラミド分子の相対量を算出した。
実施例1で得られたデータを、公知のTICを用いた方法により表示したものを図8に示す。図8において、セラミドの溶出時間帯は5分から20分であるが、TICにおいて、保持時間に基づいてセラミドのピークを特定することが困難であることは明白であった。
