The chemical components and medicinal properties of different medicinal parts of Angelica sinensis are often used as medicine after being divided into the head, body and tail of Angelica sinensis. In this study, the chemical components of different medicinal parts in different periods were analyzed by GC-MS for the first time, and the differences of the accumulation rules of chemical components in different medicinal parts of Angelica sinensis were obtained. This study demonstrated that the differences of composition accumulation in different medicinal parts of Angelica sinensis were mainly reflected in the types and relative contents of compounds. The study found that the number of compounds in different medicinal parts of Angelica sinensis in each period were different and the change rules of the same compound in different medicinal parts were also different. The number of compounds in the tail of Angelica sinensis was the least in April, and the largest in October. The content of ligustilide in the body of Angelica sinensis was higher in April and was the highest in the tail in October. The relative content of butylidenephthalide in the head was the highest in October. The relative contents of senkyunolide A and butylphthalide in the head were decreased in October, while the contents in the body and tail increased, indicating that the compounds that accumulate in the head may transfer to the body and tail in later stages of growth. This study clarified the differences in the accumulation of chemical components in different medicinal parts of Angelica sinensis, which could provide a theoretical basis for the reasons for the differences of chemical components in the different medicinal parts.
