Abstract
The methanol extract of heartwood of Cercidiphyllum japonicum (Cercidiphyllaceae) stimulated proliferation of mouse hair epithelial cells, similar to minoxidil and procyanidin B-2. (+)-Taxifolin (2), quercetin (3), myricetin (4), (+)-dihydromyricetin (5) and gallic acid (6) were isolated from C. japonicum and showed significant proliferative activities on the hair epithelial cells.
Key words
Cercidiphyllum japonicum
