荷莲豆草药材质量标准

Quality Standard of Drymaria cordata

摘要:

目的: 建立荷莲豆草的药材质量标准,为该药用植物资源的开发与利用提供实验依据.方法: 考察荷莲豆草药材的性状、显微特征;采用TLC进行定性鉴别,点样量5 μL,展开剂环已烷-三氯甲烷-乙酸乙酯-甲酸(20:3:8:0.3);检查其水分、总灰分、浸出物.结果: 不同来源荷莲豆草药材性状与显微特征一致性好;TLC鉴别特征明显,专属性强.将本品质量标准拟定为水分≤12.0%,总灰分≤13.0%;浸出物质量分数≥18.0%.结论: 建立的方法可用于荷莲豆草药材的质量控制.

Abstract:

Objective:To establish quality control specification of Drymaria cordata, and provide experimental basis for developing and utilizing of this medicinal plant resources. Method: Property identification, microscopic identification were used to identify pharmacognostical characteristics of D. cordata by TLC, sample volume was 5 μL, developing agent was cyclohexane-chloroform-acetic ether-formic acid(20: 3: 8: 0.3).Moisture, total ash and extract content were determined. Result: Morphological and histological characters of D. cordata from different origins showed good consistency.TLC identification was distinct with strong specificity.Quality standards of this product was set as following:moisture≤12.0%, total ash≤13.0%, content of alcohol soluble extract≥18.0%. Conclusion: This established method can be used for quality criteria of D. cordata.
