采用石蜡切片和组织化学定位法对蚬壳花椒营养器官的解剖结构及生物碱的分布进行研究.结果表明,蚬壳花椒根的初生木质部有三原型和四原型;幼茎表面有表皮毛和腺体,茎内含少量分泌囊和结晶;叶上、下表皮细胞结构差异显著,上表皮细胞较大,有一分泌囊紧接下表皮.生物碱组织化学定位显示,茎中生物碱主要存在于周皮、次生木质部的射线细胞及髓部细胞内;根中生物碱大量存在于周皮、次生韧皮部及次生木质部的射线细胞中;叶片中不含生物碱.采用HPLC法测定根、茎、叶及生药中的主要有效生物碱的含量,根中主要有效生物碱含量比茎中含量高.

Paraffin method and histochemistry localization method were used to study anatomical structure and alkaloids distribution observation of vegetative organs of Zanthoxylum dissitum Hemsl. The results showed that besides the basic character of dicotyledon in its vegetative organs, the primary xylem of the root was triarch and tetrarch; some epidermal hairs and glands were observed on the surface of the young stem, in the cortex, some secretory cavities were observed closely to the epidermis; the cells of the upper epidermis were obviously bigger than the lower epidermis in leaf.
