目的:
2
通过对川麦冬药材多种质控指标的检测和分析,探索该药材性状与内在质量之间的关联性,为川麦冬药材等级标准的制定提供参考。
方法:
2
对28批不同等级川麦冬药材(一等品、二等品、三等品和统货)开展性状检查、显微和薄层鉴别、水分、灰分、酸不溶性灰分、二氧化硫残留量、重金属和有害元素残留量、多效唑残留量、水溶性浸出物、总皂苷含量及3种主要成分(麦冬皂苷D,甲基麦冬黄烷酮A,甲基麦冬黄烷酮B)含量测定,分析各项指标与川麦冬药材等级之间的相关性。
结果:
2
川麦冬药材在性状、显微特征和薄层色谱方面均具有专属性特征,川麦冬药材的杂质、水分、灰分、酸不溶性灰分和水溶性浸出物在不同等级之间存在一定差异性。川麦冬一等品每50 g药材含80~120粒,水分11.1%~14.9%,灰分1.6%~2.1%,酸不溶性灰分0.03%~0.14%,水溶性浸出物77.0%~86.5%;二等品每50 g药材含120~160粒,水分13.1%~14.2%,灰分1.3%~2.2%,酸不溶性灰分0.06%~0.22%,水溶性浸出物75.9%~83.3%;三等品每50 g药材含160~300粒,杂质0.2%~8.4%,水分12.6%~14.0%,灰分1.2%~1.5%,酸不溶性灰分0.06%~0.22%,水溶性浸出物74.0%~86.5%;统货每50 g药材含80~300粒,杂质1.2%~22.6%,水分13.0%~15.4%,灰分1.4%~2.0%,酸不溶性灰分0.03%~0.15%,水溶性浸出物79.8%~85.2%。
结论:
2
川麦冬药材以每50 g所含粒数等外观性状并结合杂质、浸出物等内在指标进行等级划分具有一定合理性和可行性,可作为川麦冬药材等级标准的参考。
Objective:
2
To investigate the correlation between the characteristics and internal quality of Ophiopogonis Radix from Sichuan province through various quality evaluation
and provide reference for the formulation of grading standard of this herb.
Method:
2
For 28 batches of Ophiopogonis Radix
the characters
microscopic characteristics
thin-layer chromatography (TLC)
the content of moisture
ash content
acid insoluble ash content
residues of sulfur dioxide
heavy metals
hazardous elements and paclobutrazol
water-soluble extract
contents of total saponins and three major components [ophiopogonin D (OPD)
methylophiopogonanone A (MPOA) and methylophiopogonanone B (MPOB)] were determined.The relationships between various indicators and the grade of Ophiopogonis Radix were analyzed.
Result:
2
Ophiopogonis Radix exhibited specific properties in characters
microscopic characteristics and TLC.The contents of impurity
moisture
total ash
acid-insoluble ash and water-soluble extract existed differences in four grades of Ophiopogonis Radix from Sichuan province.For grade Ⅰ
grain number was 80-120 grains per 50 g
the moisture content was 11.1%-14.9%
total ash content was 1.6%-2.1%
acid-insoluble ash content was 0.03%-0.14%
water-soluble extract content was 77.0%-86.5%.For grade Ⅱ
grain number was 120-160 grains per 50 g
the moisture content was 13.1%-14.2%
total ash content was 1.3%-2.2%
acid-insoluble ash content was 0.06%-0.22%
water-soluble extract content was 75.9%-83.3%.For grade Ⅲ
grain number was 160-300 grains per 50 g
the impurity was 0.2%-8.4%
the moisture content was 12.6%-14.0%
total ash content was 1.2%-1.5%
acid-insoluble ash content was 0.06%-0.22%
water-soluble extract content was 74.0%-86.5%.For grade Ⅳ
grain number was 80-300 grains per 50 g
impurity was 1.2%-22.6%
the moisture content was 13.0%-15.4%
the total ash content was 1.4%-2.0%
acid-insoluble ash content was 0.03%-0.15%
water-soluble extract content was 79.8%-85.2%.
Conclusion:
2
It is reasonable and feasible to classify the grade of Ophiopogonis Radix from Sichuan province according to the appearance characteristics such as the grain number per 50 g and internal indexes such as impurity and water-soluble extract
which can be used as a reference for grading standards of Ophiopogonis Radix from Sichuan province.
