Summary

1. The roots ofLithospermum erythrorhizon Sieb. et Zucc. have yielded six naphthazarin pigments which have been characterized as shikonin itself and derivatives of it. A new quinoid pigment of nonnaphthazarin structure has also been isolated.

2. The pigments of the roots ofL. erythrorhizon collected in the Maritime Territory have not been found to contain the β,β-dimethylacrylic ester of shikonin which has been reported for this species in the literature.
