Abstract
Carthamin (safflower red dyestuff) which is highly useful but has been limited in use due to its high price, can be efficiently obtained from safflower yellow B dyestuff of which the content in safflower petals is large, and the safflower red dyestuff therefore can be stably provided at a low price.
