The ethnopharmacology, phytochemistry and pharmacology of Angelica biserrata - A review.

BACKGROUND

Angelica biserrata (R.H. Shan & C.Q. Yuan) C.Q. Yuan & R.H. Shan (Angelica pubescens Maxim. f. biserrata Shan et Yuan) (A.biserrata) is a widely used traditional Chinese medicine; its roots known as 'Duhuo' in China. The herb is used for expelling wind, eliminating dampness, and terminating pain. Moreover, it is used for treating the onset of anemofrigid-damp arthralgia, pain of the waist and knee and headache caused by latent wind pathogenic factor or damp-cold pathogenic factor. A.biserrata is slightly warm, bitter and pungent in taste, and it is well distributed in regions such as Sichuan and Hubei Provinces.

OBJECTIVE

This review aims to provide critical summary of the current evidence on A.biserrata. In particular, the progress of studies in the fields of botany, ethnopharmacology, phytochemistry, pharmacology and toxicity are discussed. Possible directions for future research are also briefly proposed.

METHODS

Information on A.biserrata was collected from the internet database PubMed, Elsevier, China Knowledge Resource Integrated databases, ResearchGate, Web of Science, Wiley Online Library and Europe PMC using a combination of various relevant keywords. Other published books providing an overview of extant literature studies were considered for reference if they are related to the taxonomy, traditional knowledge, phytochemistry, pharmacology and toxicity of the plant.

RESULTS

A substantial proportion of the isolated and identified compounds of the herb were reported to be coumarins and volatile oils. Biological effects, such as neuroprotective, anti-tumor, anti-arthritis, anti-inflammatory, and sedative, were also validated in In vitro and in vivo studies. Therapeutic effects are attributed to the bioactivities of the naturally occurring compounds in this herb.

CONCLUSIONS

A.biserrata has been proven as a valuable medicinal sources from traditional herb. Some conventional uses has been evaluated by pharmacological investigation. Although the crude extracts of A.biserrata has been emerged to possess more pharmacological activities, it is now time to isolate and identify more active chemical constituents by Bioactivity-Guided and elucidate their structure-activity relationship. More designed investigations are need to focus on understanding the multi-target network pharmacology, clarity the molecular mechanism of action and efficacy as well as identifying the effective doses of A.biserrata. In addition, A.biserrata is not fully assessed regarding its safety. Further studies are essential to investigate its toxicity on human. It's useful to provide identify its underlying therapeutic remedy and economic value of developing new medicine in the future.
