割秧对黄芩生长以及药材、茎叶的产量和质量影响研究

通过测量不同割秧茬数处理下黄芩的生长指标,并采用紫外和HPLC测定药材中总黄酮、黄芩苷、汉黄芩苷、黄芩素、汉黄芩素、千层纸素A和茎叶中总黄酮、野黄芩苷、黄芩苷、芹菜素、木犀草素的含量。该文发现在保证不过度影响药材质量和产量的前提下,进行两茬割秧处理后,不仅黄芩药材和茎叶的产量增加,分别可达193.60,63.21 kg/亩,其所含活性成分含量也具有一定的提高。其中,黄芩药材中所含总黄酮,黄芩苷,汉黄芩苷,黄芩素,汉黄芩素,千层纸素A的质量分数分别可达18.52%,15.13%,4.03%,1.04%,0.30%,0.12%。在两茬处理下的黄芩茎叶中并未检测到木犀草素,但其他活性成分如总黄酮、野黄芩苷、黄芩苷、芹菜素的质量分数分别已经达到7.00%,0.96%,0.35%,0.04%。故为获取优质黄芩药材和高产药材及茶原料,从药用植物资源合理利用和推动药茶两用黄芩一体化发展出发,定期割秧可以作为一种新的栽培采收技术被广泛推广。

Influence of cutting seedling on growth, quality and yield of both aerial and underground part by cutting seedling in Scutellaria baicalensis

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.
