目的:为更好的开发利用药材银合欢叶提供鉴别特征参考。方法:采用性状鉴别和显微鉴别法。结果:性状鉴别的主要特征:叶柄基部具膨大的叶枕,基部一对羽片间有一个浅杯状腺体;小叶片主脉偏向一侧。显微鉴别主要特征:叶柄中部维管束有7个,维管束有纤维束包围,纤维束外侧有方晶环,髓部呈五角星形;小叶片为等叶面,上面的栅栏组织通过主脉,下面的栅栏组织断续排列,维管束有维管束鞘;小叶片上下表面均有气孔。粉末:可见非腺毛和晶鞘纤维,方晶众多,有具缘纹孔和螺纹导管。结论:上述特征可作为制定药材质量标准、利用和开发药材资源提供鉴别参考依据。
Objective: To provide a reference for better development and utilization of medicinal materials, silver leaf. Methods: The character identification and microscopic identification method. Results: The main traits of character traits were: leaf bases at base of petioles with a shallow cup-shaped gland between a pair of feathers; Microscopic identification of the main features: the middle of the petiole vascular bundles of seven, the vascular bundles surrounded by fiber bundles, fiber bundles outside the crystal ring, pentagonal pentagonal star; small leaflets for the same foliage, the above palisade tissue through the main vein, the following Of the palisade tissue intermittent arrangement, vascular bundles vascular bundle sheath; small leaf on the upper and lower surfaces have stomata. Powder: visible non-glandular hair and crystal sheath fibers, many crystal, with a margin of holes and threaded catheter. Conclusion: The above characteristics can be used as a reference for formulating quality standards of medicinal materials and utilizing and developing medicinal resources.
