中医临床以侧柏叶作止血药使用。徐振文等认为侧柏叶中的止血成分可能是槲皮甙和鞣质;小岛卓夫等以Tajimas止血方法为指标,经过系统的分离和筛选,确证了侧柏叶的止血活性成分是槲皮甙。我们从侧柏叶中分离到槲皮甙,用HPLC法测定了侧柏叶中槲皮甙的含量,为侧柏叶的质量评定建立了分析方法。
Traditional Chinese medicine uses arborvitae leaves as a hemostatic agent. Xu Zhenwen et al. believe that the hemostatic component of T. chinensis leaves may be ecdysteroids and tannins; Tajima Kojima et al. used Tajimas hemostasis as an indicator. After systematic isolation and screening, it was confirmed that the hemostatic active ingredient of Platycladus orientalis leaves was ecdysteroids. . We isolated eucalyptus from oriental arborvitae leaves and determined the content of quercitrin in oriental arborvitae leaves by HPLC. The analytical method was established for the quality assessment of oriental arborvitae leaves.
