目的:建立横经席专属性鉴别方法.方法:采用性状、显微及薄层色谱相结合的方法对横经席及其同属品种绣毛红厚壳、红厚壳进行对比研究,找到横经席的鉴别特征.结果:横经席性状鉴别特征为叶呈长圆状披针形,两面无毛;锈毛红厚壳叶呈矩圆形至椭圆形,两面主脉及小枝均密被锈红色柔毛;红厚壳叶呈宽椭圆形或倒卵状椭圆形,两面无毛.横经席粉末显微特征可观察到叶表皮细胞、纤维等,无非腺毛;锈毛红厚壳粉末可见较多非腺毛;红厚壳叶下表皮细胞垂周壁波浪状弯曲并呈连珠状增厚.薄层色谱鉴别结果显示,横经席比同属其他品种多1个特征斑点.结论:研究建立的横经席鉴别方法具有专属性,可区别横经席正品及其混伪品.
Study on Identification of Guangxi Characteristic Medicinal Materials Calophylli Herba
Objective:To establish the identification method with specificity for Calophyllum membranaceum Gardn.et Champ.Method:A comparative study was carried out on Calophyllum membranaceum Gardn.et Champ and its congener Calophyllum antillanum Britt and Calophyllum inophyllum L to determine the identification characteristics of Calophyllum membranaceum Gardn.et Champ by using the characteristics,microscopic thin-layer chromatography(TLC)methods.Results:The character identification of Calophyllum membranaceum Gardn.et Champ was that the leaves were oblong lanceolate and hairless on both sides.The leaves of Calophyllum antillanum Britt.were rectangular round to oval,both main veins and branchlets were densely rusty-red pilose.The Calophyllum inophyllum L.leaves were broadly oval or obovate oval,hairless on both sides.The microscopic characteristics of Calophyllum membranaceum Gardn.et Champ powder could be observed leaf epidermal cells,fibers and so on,no non-glandular hairs.More non-glandular hairs could be seen in Calophyllum antillanum Britt.The vertical wall of the lower epidermal cells of Calophyllum inophyllum L.leaves was wavy curved and thickened in a bead shape.The TLC identification results showed that there was one more characteristic spot than other varietiesin the same genus.Conclusion:The established method for the identification of Calophyllum membranaceum Gardn.et Champhas special property,which could distinguish between genuine and mixed counterfeit goods of Calophyllum membranaceum Gardn.et Champ.
