一种从虎舌草（Phallusia mamillata Cuv.）血液中获得稳定的血钒素溶液的方法。本文介绍所有操作必须在pH 2.4下进行。天然血钒素在需氧和厌氧条件下都能降低细胞色素c。V2O2溶液也会还原细胞色素c。还原以1比1的化学计量比V++：Fe+进行。动物的精子和成熟的卵子含有细胞色素c。在其他组织中未发现色素。氰化物不会抑制血钒素对细胞色素c或亚甲蓝的还原能力。
A method for obtaining stable solutions of haemovanadin from the blood of Phallusia mamillata Cuv. is described. It is essential that all operations be carried out at pH 2.4. Native haemovanadin reduces cytochrome c both under aerobic and anaerobic conditions. Solutions of V2O2 also reduce cytochrome c. The reduction takes place with a stoichiometric ratio V++: Fe+++ of one to one. The sperm and ripe eggs of the animal contain cytochrome c. The pigment was not found in other tissues. Cyanide does not inhibit the reducing power of haemovanadin towards cytochrome c or methylene blue.
