每一种植物的内部构造都有一些特点,因此通过制作切片后进行观察,根据内部构造的特点可以鉴别植物性药材的真伪。石蜡切片是显微技术上最常用的一种方法,一般材料都可采用,能切成薄至1μm的片子和连续的切片。石蜡切片的操作比较复杂,需要经过多种步骤。虽然比较麻烦,但在熟练以后,也就感到易于处理了。切片的厚度是很重要的,它和每一种植物的内部构造,均有密切关系。除考虑各组织的清晰程度外,尚需考虑每种切片的用途。一般而论,疏松的材料,可切得较厚,紧密的材料,可切得较薄。从组织学观察的要求而论,一般
The internal structure of each plant has some characteristics. Therefore, after making slices and observing, the authenticity of plant herbs can be identified according to the characteristics of internal structures. Paraffin sections are one of the most commonly used microscopy methods. General materials can be used. They can be cut into thin slices up to 1 μm and continuous sections. The operation of paraffin sections is complex and requires many steps. Although it is more troublesome, it feels easy to handle after being proficient. The thickness of the slice is very important, and it is closely related to the internal structure of each plant. In addition to considering the clarity of the organizations, the use of each slice needs to be considered. In general, loose materials can be cut thicker and denser materials can be cut thin. Considering the requirements of histological observation, generally
