Chika Kuroda (黒田チカ; 24 March 1884 – 8 November 1968) was a Japanese chemist whose research focused on natural pigments.

[1] She attended the Women's Department of Saga Normal School, graduating in 1901, and worked as a teacher for a year afterward.

[7] Throughout the 1930s and 1940s, Kuroda's research examined the pigments of the Asiatic dayflower, eggplant skin, black soybeans, red shiso leaves, and sea urchin spines, as well as derivatives of naphthoquinone.

Her extraction of quercetin crystals from onion skin led to the creation of Kerutin C, an antihypertensive drug.

[4] Tohoku University created the Chika Kuroda prize in 1999 to recognize outstanding accomplishments for graduate students in science.
