Studies on the nutritional analysis and breeding utilization of the leaf of Japanese butterbur

佐都岛野生毛茛叶中含有的主要酚类化合物为绿原酸、福烯酸、3,5 -二咖啡酰基奎宁酸和3,4,5 -三咖啡酰基奎宁酸。从65个地点采集的叶片样品中，苯丙素含量与绿原酸的差异为4。41次，福田酚酸为1。95倍，3,5 -二咖啡酰奎宁酸为4。65次，3,4,5 -三咖啡基奎宁酸为4次。72次。采集点海拔高度与雄株百分率呈显著正相关。雄性植株的百分比与3,5 -二咖啡酰奎宁酸的含量之间也存在很强的相关性

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
