| 摘要： | 目的 对民族药水河剑药材的质量标准进行研究，为其质量控制提供参考。方法对水河剑药材进行性状、显微及薄层色谱鉴别，并测定其水分、灰分及浸出物；采用高效液相色谱法测定10批水河剑药材中绿原酸和芦丁的含量。结果水河剑根状茎细长横走，叶革质皱缩，叶下着生黄色孢子囊群。水河剑药材叶片横切面可见内含物、厚壁组织、韧皮细胞等；叶柄横切面可见基本组织、厚壁组织、内皮层等；根状茎横切面可见基本组织、管胞、维管束等；粉末可见螺纹导管和棕色内含物。薄层色谱鉴别结果显示，供试品色谱与绿原酸对照品色谱在相应位置上显相同颜色的斑点。10批样品中水分、总灰分、酸不溶性灰分、浸出物、绿原酸和芦丁含量范围分别为10.18%～12.43%、7.08%～19.12%、0.95%～10.62%、14.13%～26.05%、0.1131～1.0159mg/g和0.0099～0.2089mg/g。结论水河剑药材的质量标准中，水分含量应≤12.5%，总灰分含量应≤20.0%，酸不溶性灰分含量应≤11.0%，浸出物含量应≥14.0%，绿原酸含量应≥0.11mg/g。所建方法操作简便、专属性强、重复性好，可为水河剑药材的质量控制提供科学依据。 |
| ABSTRACT： | Abstract OBJECTIVE To study the quality standard of the ethnic medicine Diplazium lanceum， and to provide reference for its quality control.METHODS The medicinal material of D. lanceum was identified by properties， microscopy， and thin-layer chromatography（TLC）， and its moisture， ash， and extract contents were determined. The contents of chlorogenic acid and rutin in 10 batches of D. lanceum were determined by high-performance liquid chromatography . RESULTS The rhizome of D. lanceum is slender and creeping， the leaf is leathery and shriveled， and yellow sporangia are borne on the abaxial surface of the leaf. The transverse section of the leaf shows inclusions， sclerenchyma， phloem cells， etc.； the transverse section of the petiole shows ground tissue， sclerenchyma， endodermis， etc.； the transverse section of the rhizome shows ground tissue， tracheids， vascular bundles， etc.； and the powder shows spiral vessels and brown inclusions. The TLC identification results showed that the chromatogram of the test sample exhibited spots of the same color at the corresponding positions as the chromatogram of the chlorogenic acid reference substance. The content ranges of moisture， total ash， acid-insoluble ash， extract， chlorogenic acid， and rutin in the 10 batches of samples were 10.18%-12.43%， 7.08%-19.12%， 0.95%-10.62%， 14.13%-26.05%， 0.113 1-1.015 9 mg/g， and 0.009 9-0.208 9 mg/g， respectively. CONCLUSIONS In the quality standard of D. lanceum， the moisture content should be ≤12.5%， total ash content should be ≤20.0%， acid-insoluble ash content should be ≤11.0%， extract content should be ≥14.0%， and chlorogenic acid content should be ≥0.11 mg/g. The established method is simple， specific， and reproducible， and can provide a scientific basis for the quality control of D. lanceum. |
