By measuring the growth data of Scutellaria baicalensis in different cutting-seedling and determined active ingredient contents by HPLC and ultraviolet spectrophotometric determination. such as flavonoids. baicalin. wogonoside. baicalein. wogonin. oroxylin A. scutellarin. luteolin. and apigenin in the whole plant. Under circumstances of guaranteeing the quality and yield of medicinal materials. the yield of medicinal materials. and stems and leaves reached 193.60,63.21 kg/mu after twice cutting seedling. Not only yield but also active ingredient contents have been improved to some extent. the contents of flavonoids. baicalin. wogonoside. baicalein. wogonin. oroxylin A reached 18.52%. 15.13%. 4.03%. 1.04%. 1.04%. 0.12%. respectively in roots. Luteolin was not detected in young stems and leaves of S. baicalensis,the contents of other active ingredients such as scutellarin. luteolin and apigenin reached 7.00%. 0.96%. 0.04% respectively under twice cutting seedling. Therefore. regular cutting seedling could be regard as a new cultivation technique for wider range of promotion. And gaining high quality and yield of medicinal materials and tea with the purpose of rational utilization of natural resources and promoting the development of integration of herbal combination.
通过测定不同扦插苗龄黄芩的生长数据，并采用高效液相色谱法和紫外分光光度法测定其活性成分含量，如全株中的黄酮类、黄芩苷、汉黄芩苷、黄芩素、汉黄芩素、木犀草素、野黄芩苷、木犀草素和芹菜素。在保证药材质量和产量的情况下，二次扦插苗龄后药材、茎和叶的产量分别达到193.60、63.21kg/亩。不仅产量有所提高，活性成分含量也有一定程度的提升，根中黄酮类、黄芩苷、汉黄芩苷、黄芩素、汉黄芩素、木犀草素的含量分别达到18.52%、15.13%、4.03%、1.04%、1.04%、0.12%。黄芩幼茎和叶中未检测到木犀草素，二次扦插苗龄下野黄芩苷、木犀草素和芹菜素等其他活性成分的含量分别达到7.00%、0.96%、0.04%。因此，定期扦插苗龄可作为一种新的栽培技术进行更广泛推广。以合理利用自然资源、促进药茶一体化发展为目的，获得高质量和高产量的药材及茶。
