长苞香蒲(Typha angustata Boryet Chanb)系香蒲科植物,为常用中药之一,其有止血祛淤的功效。用于咯血、吐血,脘腹刺痛,外伤出血,跌打损伤等症。近年临床及药理研究表明,长苞香蒲具有降低血中总胆固醇、增加冠脉流量、抗菌等多种作用。关于长苞香蒲的化学成分,近年已有报道①～④。其氨基酸成分,徐启福等报道含缬氨酸、丙氨酸、亮氨酸等成分①。但经纸层析展示,长苞香蒲的水溶性成分含多种氨基酸,为弄清此类成分,我们对长苞香蒲的氨基酸进行了种类及含量的测定。
Typha angustata Boryet Chanb is one of the commonly used traditional Chinese medicines of Typha angustata Boryet Chanb. It has the effect of stopping bleeding and stasis. For hemoptysis, vomiting, abdominal tingling, traumatic bleeding, bruises and other embolism. In recent years, clinical and pharmacological studies have shown that Changyi cattail has various effects such as lowering total cholesterol in the blood, increasing coronary flow, and antibacterial activity. About the chemical composition of Changyi cattail, 1 to 4 have been reported in recent years. Its amino acid composition, reported by Xu Qifu et al., contained components such as proline, alanine, and leucine. However, paper chromatography showed that the water-soluble components of T. glauca contain multiple amino acids. To clarify these components, we have determined the species and content of T. glauca.
