Preliminary studies showed that there is a close relationship between plant structure and chemical composition. To explore the relationship between structural development and anatomical structure of J. rigida needles, and increasing the extraction rate, ensuring the quality of J. rigida needles, the histochemical study was extremely essential.

There are no previous studies on the anatomy of the needles of J. rigida species, so the diagnostic and morphoanatomical characterization of this plant drug is limited. In addition, studies on the phytochemical profiling of the J. rigida species have been done in some general ways with a focus on the chemical composition in needles of J. rigida species, but no research has been done to reveal the dynamic of altitudinal change.

A lot of research for other plants has been done on the histochemistry of phenols and essential oil. The histochemistry of phenols in Baccharis spicata showed that the phenols present the phloem and the fiber caps.

Thereby, it is very necessary for the histochemical study of phenols and terpenoids, the research results can provide information for the accumulation of secondary metabolites of J. rigida, and provide a scientific basis for the comprehensive utilization of J. rigida.

Preliminary studies showed that there is a close relationship between plant structures and chemical composition. To explore the relationship between the structural development and anatomical structure of J. rigida needles, increase the compound extractionrate, and ensure the quality of J. rigida needles, the histochemical study is extremely essential.

A lot of research for other plants has been done on the histochemistry of phenols and essential oil. The histochemistry of phenols in Baccharis spicata shows that the phenols are present in the phloem and the fiber caps.

Therefore, a histochemical study of phenols and terpenoids is very important in that the results can provide information for the accumulation of secondary metabolites in J. rigida and thus add to the literature for the extensive utilization of this plant.
