グアバ葉を水又は親水性溶媒、又はこれらの混合物により抽出し、得られた抽出液を部分濃縮し、部分濃縮液から抽出溶媒に難溶性の物質を除去した後、部分濃縮液を再度濃縮することを特徴とするグアバ葉エキスの製造方法。A method for producing a guava leaf extract, comprising extracting guava leaves with water or a hydrophilic solvent, or a mixture thereof, partially concentrating the resulting extract, removing from the partially concentrated solution substances that are poorly soluble in the extraction solvent, and then concentrating the partially concentrated solution again. 部分濃縮が、室温〜７０℃において、元の抽出液の体積の５０〜８０％になるまで減圧濃縮することにより行われる請求項１記載の方法。2. The method according to claim 1, wherein the partial concentration is carried out by concentrating the extract under reduced pressure at room temperature to 70°C until the volume of the extract reaches 50 to 80% of the original volume. 難溶性の物質の除去を、部分濃縮液を５〜２０℃で放置して沈降する物質を除去すること、及び／又は、部分濃縮液を炭化水素溶剤で処理し、有機溶剤可溶性成分を除去することにより行う請求項１又は２のいずれかに記載の方法。3. The method according to claim 1, wherein the removal of the hardly soluble substances is carried out by leaving the partially concentrated solution at 5 to 20°C and removing the precipitated substances, and/or by treating the partially concentrated solution with a hydrocarbon solvent to remove the organic solvent-soluble components.
