A method for producing a special extract derived from symphite, the step of providing a suspension system derived from symphite, and the step of fractionally precipitating mucopolysaccharide in the suspension system, wherein the fractional precipitation is The first fractionated viscous precipitation is carried out to obtain the high molecular weight mucopolysaccharide as the first precipitate in the suspension system, and the first precipitate and the extraction residue that is the raffinate are separated. Obtaining a first extraction phase and performing a second fractional viscous precipitation to obtain a low molecular weight mucopolysaccharide from the first extraction phase as a second precipitate, the second precipitate And obtaining a second extract phase, selectively removing pyrrolizidine alkaloids from the second precipitate and / or the second extract phase, and the second extract phase. 2 in which the precipitate of 2, especially pyrrolizidine alkaloids has been removed. At least one of the step of combining the precipitate and the second extraction phase, particularly the second extraction phase from which the pyrrolizidine alkaloids have been removed, into the special extract, and particularly these steps Manufacturing method including all of.シンフィツム由来の特殊な抽出物の製造方法であって、シンフィツム由来の懸濁液系を提供する工程と、上記懸濁液系中でムコ多糖類を分別沈殿する工程であって、上記分別沈殿は、第１の分別粘質沈殿を実施して上記懸濁液系中において高分子ムコ多糖類を第１の沈殿物として得て、上記第１の沈殿物、およびラフィネートである抽出残渣を分離し、第１の抽出相を得ることと、第２の分別粘質沈殿を実施して上記第１の抽出相から低分子ムコ多糖類を第２の沈殿物として得て、上記第２の沈殿物を分離し、第２の抽出相を得ることとを含む、工程と、上記第２の沈殿物および／または上記第２の抽出相からピロリジジンアルカロイド類を選択的に除去する工程と、上記第２の沈殿物、特にピロリジジンアルカロイド類を除去した上記第２の沈殿物、および上記第２の抽出相、特にピロリジジンアルカロイド類を除去した上記第２の抽出相を合わせて、上記特殊な抽出物とする工程と、のうち少なくとも１つ、特にはこれらの工程の全てを含む、製造方法。
