摘　　要：目的:研究不同栽培年限及采收月份对黄芩药材有效成分含量的影响,确定最佳采收时间,为规范化种植和合理开发利用黄芩提供理论依据。方法:采用裂区试验布置田间试验,以采收年限为主因素,采收月份为副因素;采用HPLC测定黄芩中黄芩苷、黄芩素、汉黄芩苷、汉黄芩素及千层纸素A的含量。结果:无论是二年生还是三年生黄芩,其黄芩苷和汉黄芩苷含量最高均出现在春季(5月中旬至6月中旬),而黄芩素、汉黄芩素和千层纸素A含量最高峰出现稍晚(6月中旬至7月中旬)。结论:黄芩苷、汉黄芩苷、黄芩素、汉黄芩素、千层纸素A 5种成分含量最高均出现在5月到7月间,而且二年生和三年生黄芩中成分含量变化规律相近。此外,三年生黄芩药材中各个成分含量在一定程度上均有所提高,但并不明显。因此,如果以这些成分作为黄芩药材质量的考核指标,春季是适宜的采收期。Objective： In order to provide a basis for good agriculture practice and exploitation for Scutellaria baicalensis, the effect of different cultivation years and havesting period of S. baicalensis on active ingredients was studied. Methods： Split plot was used to design field experiment, the cultivation years was used as a main factor, and harvesting period as factor. The main contents of S. baicalensis were deterrhined by HPLC. Results： The highest contents of baicalin and wogonoside of the biennial and three year-old S. baicalensis appeared in spring （ mid-may-mid-June）, and the highest contents of baicalein, wogonin and oroxylin A occurred were later （mid-June-mid-July）. Conclusion： The highest content of main compositions appeared from May to July, and the changes between biennial and three year-old S. baicalensis were similar. Moreover, the total content of three year-old S. baicalensis increased to some extent, but not apparently. Therefore, the suitable time for harvesting was in spring.
