不同育苗期、移栽期和采收期川泽泻质量变化研究

目的以川泽泻中主要成分23-乙酰泽泻醇B和24-乙酰泽泻醇A为指标成分,并通过HPLC指纹图谱比较,进行质量制定。方法采用梯度洗脱法进行色谱分离,使用"中药指纹图谱相似度计算软件"和DPS软件进行数据处理。结果在6月25日育苗、9月10日移栽和当年的12月下旬初采收,川泽泻药材的总体质量最佳。结论随着育苗期、移栽期和采收期的后延,川泽泻药材总体质量下降。

Quality change on Alisma plantago-aquatica at various growing-seedling stages, transplanting stages, and collecting stages

Objective To establish the quality standard of Alisma plantago-aquatica through comparing systematically the changes of HPLC fingerprint of 23-alisol B and 24-alisol A, and other corresponding components as well. Methods The gradient elution mode was applied in chromatographic separation and data were analyzed by "Computer Aided Similarity Evaluation" software and DPS statistic software. Results Total quality of A. plantago-aquatica was the best when grow-seedling was at 25th, June, transplanting at 10th, September, and collecting at 22nd, December in the same year. Conclusion Total quality will drop along with the postponement of grow-seedling stage, transplanting stage, and collecting stage.
