Pharmacognostical study of Croton Crassifolius Geisel

Objectives

Croton Crassifolius Geisel of the genus Croton in the Euphorbia family is a widely distributed herb in South China. It has medicinal value for the treatment of a sore throat, soothing tendons, activating collateral, and treating rheumatoid arthritis. Although it has been traditionally used in Chinese medicine, there has been no systematic study on its identification and classification of the authenticity of this plant. The purpose of this study is to provide a scientific basis for the identification and classification of the authenticity of this plant.

Methods

An accurate and effective identification system was established through morphological characteristics, microscopic characteristics, physical and chemical parameter determination, phytochemical screening, and DNA barcoding analysis.

Results

The physicochemical results revealed that this plant might contain flavonoids, cardiac glycosides, and alkaloids. The ITS locus in the nuclear genome in the chloroplast genome was screened and evaluated and Neighbor-Joining phylogenetic trees can effectively identify Croton Crassifolius Geisel to a certain extent.

Conclusion

This research contributed to the development of species identification.
