| Research Abstract |
Major phenolic compounds contained in the leaf of wild Japanese butterbur collected on Sado island were chlorogenic acid, fukinolic acid, 3, 5-dicaffeoylquinic acid, and 3, 4, 5-tricaffeoylquinic acid. The difference between the phenylpropanoid content of the leaf samples collected from 65 locations, chlorogenic acid was 4. 41 times, fukinolic acid was 1. 95 times, 3, 5-dicaffeoylquinic acid was 4. 65 times, and 3, 4, 5-tricaffeoylquinic acid was 4. 72 times. A strong correlation was observed between the elevation of points collected samples and the percentage of male plants. A strong correlation was also observed between the percentage of male plants and the content of 3, 5-dicaffeoylquinic acid
