畲药地稔药材的质量标准研究

Study on the quality specification of traditional She medicine Melastoma dodecandrum Lour.

目的:研究畲药地稔药材的质量标准,为该药用植物资源的开发利用提供科学依据。方法:运用显微鉴别法、薄层色谱法、高效液相色谱法分别对地稔的显微特征、指标性成分没食子酸、槲皮素进行定性定量测量。结果:没食子酸回归方程为Y=2×106X+2.3026,r=0.9998,槲皮素回归方程为Y=6×104X+5.1521,r=0.9996。没食子酸和槲皮素分别在0.0814-0.3260μg、0.0271-0.1360μg内呈线性。结论:研究所得方法简便,准确,可有效控制地稔药材的质量。

Objective： To provide scientific basis for the utilization and development of Melastoma dodecandrum by setting up the quality control specification. Methods： Application of microscopical identification, TLC, HPLC to Minoru microscopic characteristics, target components of gallic acid, quercetin qualitative and quantitative measurement. Results： Gallic acid regression equation is Y=2x 106X＋2.3026, r=0.9998, quercetin regression equation is F=6x 104）（＋5.1521, r=-0.9996. Gallic acid and quercetin in respectively 0.0814-0.3260μg, 0.0271-0.1360μg is linear. Conclusion： The method is simple, accurate, and can effectively control the quality of Meiastoma dodecandrum.
