1−1:ソウハクヒのメタノール抽出物
乾燥したソウハクヒ(3kg)を10Lのメタノールで4時間ずつ3回繰り返し還流抽出し、濾過した後、減圧濃縮して150gのメタノール抽出物を得た。
前記1−1で製造したソウハクヒのメタノール抽出物(150g)を6Lの水に懸濁し、ヘキサン(3L、3回)と酢酸エチル(3L、3回)に順次分配し、ヘキサン抽出物(50g)および酢酸エチル抽出物(50g)を得た。この酢酸エチル抽出物をシリカゲルカラムクロマトグラフィー(シリカゲルカラム500g)処理し、ジクロロメタン(CH2Cl2)−メタノール(70%:30%、50%:50%、30%:70%、10%:90%、0:100%)から構成される段階濃度勾配溶媒システムを適用して25個の小分画物(MAE−01〜25)を得た。
前記1−2で製造した酢酸エチルの小分画MA.E−16を逆相シリカゲル(RP−18)カラムクロマトグラフィー(メタノール:水=1:1→3:1、メタノール、段階濃度勾配システム)処理し、小分画物15個の分画物(MA.E−1601〜1615)を得た。これから得た分画物MA.E−1607を逆相シリカゲルクロマトグラフィー(RP−18、メタノール:水=1:1(2000mL→2:1(1000mL)処理して10個の小分画(160701〜160710)に分け、この中でもMA.E−160709を分取用高速液体クロマトグラフィー(HPLC、Sunfire(登録商標) C18、5μm、19×150mm i.d.、50%アセトニトリル、285nm、5mL/min)処理し、分離精製して前記[化1]のムルベロフランG(50mg)を得た。
