The invention refers to a method for obtaining polyhydroxy 1,4-naphthoquinones from live sea urchins, comprising the following steps:
a) injecting a KCl saline solution into the perivisceral coeloma of female sea urchins to induce spawning;
b) collecting the eggs, and grinding them into a fine powder;
c) mixing said fine powder with an alcoholic solvent;
d) separating the alcohol supernatant comprising the polyhydroxy 1,4-naphthoquinones in solution.
Where the polyhydroxy 1,4-naphthoquinones are selected from: echinochrome A (6-ethyl-2,3,5,7,8-pentahydroxy-1,4-naphthoquinone), spinochrome A (2-acetyl-3,5,6,8-tetrahydroxy-1,4-naphthoquinone), spinochrome B (2,3,5,7-tetrahydroxy-1,4-naphthoquinone), spinochrome C (2-acetyl-3,5,6,7,8-pentahydroxy-1,4-naphthoquinone), spinochrome D (2,3,5,6,8-pentahydroxy-1,4-naphthoquinone), spinochrome E (hexahydroxy-1,4-naphthoquinone) or mixtures thereof.
本发明涉及一种从活海胆中获得多羟基 1,4-萘醌的方法,包括以下步骤:
a) 将氯化钾盐溶液注射到雌性海胆的脐周海绵体中,以诱导产卵;
b) 收集卵,并将其研磨成细粉
c) 将上述粉末与酒精溶剂混合;
d) 分离含有多羟基 1,4-萘醌溶液的酒精上清液。
其中多羟基 1,4-萘醌选自echinochrome A (6-ethyl-2,3,5,7,8-pentahydroxy-1,4-naphthoquinone), spinochrome A (2-acetyl-3,5,6,8-tetrahydroxy-1,4-naphthoquinone), spinochrome B (2,3,5,7-tetrahydroxy-1,4-naphthoquinone)、或它们的混合物。
