Comparative analysis of chloroplast genomes of three medicinal Carpesium species: Genome structures and phylogenetic relationships.

Carpesium (Asteraceae) is a genus that contains many plant species with important medicinal values. However, the lack of chloroplast genome research of this genus has greatly hindered the study of its molecular evolution and phylogenetic relationship. This study used the Illumina sequencing platform to sequence three medicinal plants of the Carpesium genus: Carpesium abrotanoides, Carpesium cernuum, and Carpesium faberi, obtaining three complete chloroplast genome sequences after assembly and annotation.

[Determination of quercetin and kaempferol in Dysosma plants by RP-HPLC].

Objective: To determine quercetin and kaempferol in the plant of genus Dysosma that come from different species, different plant parts or different growing areas, which provide the basis of rational utilization of Dysosma plants.

Method: The analysis was performed on a Diamonsil C18 column (4.6 mm x 150 mm, 5 microm) eluted with the mobile phase of methanol-water containing 0.
