| 中文摘要: |
| 【目的】研究不同产地绞股蓝的水分、灰分和浸出物含量，并设置其质量控制项目和限量，为提升绞股蓝的质量标准提供参考依据。【方法】采用《中国药典》（2020年版）四部通则中相关检测方法对绞股蓝中的水分、总灰分、酸不溶性灰分、水溶性浸出物的含量进行测定。【结果】不同产地、不同部位的绞股蓝水分、浸出物、总灰分和酸不溶性灰分之间有一定差异。所有75批次绞股蓝，全草的含水量最高，与龙须、叶、茎和叶3种部位的含水量均具有显著性差异。其中药用绞股蓝水分含量为8.31%~12.78%，总灰分含量为9.41%~20.19%，酸不溶性灰分含量除样品部位为茎之外的19批样品外均在0.57%~6.99%范围，水溶性浸出物含量为20.86%~39.79%。55批次茶饮绞股蓝中，水分含量仅14批次达标，总灰分含量19批次合格，产地为陕西、湖北和福建的绞股蓝浸出物含量较其他省份高。【结论】综合分析药茶绞股蓝现有的质量控制和本研究实验结果，建议制定统一标准。将水分、总灰分、酸不溶性灰分和水溶性浸出物（热提法）四项检查均设置为各省绞股蓝药材质量控制项目，拟定药用绞股蓝的水分、总灰分含量分别不得超过12.0%、16.0%，酸不溶性灰分不高于3.0%，水溶性浸出物（热浸法）含量不低于25.0%；茶饮绞股蓝可依据使用部位不同制定相应的质量控制标准。 |

| 【Objective】To Study the moisture, ash and extract content of Gynostemma pentaphyllum(GP) from different habitats,and we discussed the items and limits of quality control to provide reference for the quality standard of GP. 【Method】The contents of moisture, total ash, acid-insoluble ash and water-soluble extractives of GP from different areas, were determined according to general provisions 0832, 2302, 2201 of Chinese Pharmacopoeia (2020 Edition).【Result】There are certain differences among the moisture, water-soluble extract, total ash and acid-insoluble ash of GP from different producing areas and different parts. Among all 75 batches of GP, the moisture content of the whole plant is the highest, and there are significant differences between the three parts of tendrils, leaves and stem mixed with leaves. The moisture content of medicinal GP ranges from 8.31% to 12.78%; the total ash content ranges from 9.41% to 20.19%,; the acid-insoluble ash content was in 19 batches of samples except for stems, ranging from 0.57% to 6.99%; the water-soluble extractive content was between 20.86% and 39.79%.Among 55 batches 0f tea GP, only 14 batches of moisture content and 19 batches of total ash content were qualified, the extract content in Shaanxi, Hubei and Fujian wan higer than that in other provices.【Conclusion】Comprehensive analysis of the existing quality control of medicinal and tea GP and experimental results of this study, It is recommended that a unified standard should be developed. Four inspections of moisture, total ash, acid-insoluble ash, and water-soluble extracts are set as quality control items of medicinal GP in each province, which including the moisture content of medicinal GP should not exceed 12.0%, the total ash content should not exceed 16.0%, the acid-insoluble ash content should not exceed 3.0%, and the water-soluble extractive content should not be less than 25.0%, tea of GP can be based on the use of different parts to develop appropriate quality control standards. |
