With the application of artificial fertilizers and pesticides, the quality of the artificial medicinal plants has been found to be in a marked decline. The present paper focuses on the separation of endophytes from wild Angelica sinensis and the effects of endophytes on the growth of A. sinensis and synthesis of secondary metabolites. In this study, the endophytes, namely actinomycetes, fungi, and bacteria, were isolated. Z-ligustilide and ferulic acid were analyzed by HPLC. Our results confirmed that the contents of Z-ligustilide and ferulic acid showed an obvious increase on adding the endophytic fungi, but the additions of the endophytic actinomycetes and bacteria had shown inhibiting effects. Compared with the control group, the contents of Z-ligustilide and ferulic acid in the fungi group increased by 4.12- and 6.53-fold, respectively. This work demonstrates the fact that endophytic fungi can enhance the growth of plants and the production of natural products in A. sinensis.
