comparison between the three species and determination of the phenolic pattern inheritance in S. anglica. A total of 20 phenolic compounds were detected in the aerial tissues of S. anglica and S. alterniflora, but only seven in S. maritima. They were isolated from their respective crude extracts, and their structures were determined according to spectroscopic data analysis and chemical evidence. They all belong
入侵物种 Spartina anglica 起源于欧洲,由非洲-欧洲物种 S. maritima(本地、父系祖先)和引入的北美互花米草(入侵、母系祖先)杂交而成。从植物组织中制备含水甲醇提取物,用于三个物种之间的化学分类比较,并确定 S. anglica 中的酚类遗传。在 S. anglica 和 S. alterniflora 的地上组织中共检测到 20 种酚类化合物,但在 S. maritima 中仅检测到 7 种酚类化合物。它们从各自的粗提物中分离出来,并根据光谱数据分析和化学证据确定了它们的结构。它们都属于黄酮类,其中 13 种被鉴定为 C-糖类黄酮,7 种被鉴定为 O-糖类黄酮。所有这些产品均为首次从S. anglica 中检测到,其中14 种为首次从S. alterniflora 中检测到,其中3 种为首次从S. maritima 中检测到。通过定量 HPLC 测定三种物质中的
