Apiaceae Medicinal Plants: A Review of Traditional Uses, Phytochemistry, Bolting and Flowering, and Controlling Approaches

Abstract

Ethnopharmacological relevance: Apiaceae plants have been widely used as traditional Chinese medicines (TCMs) for the treatment of removing dampness to relieve pain, relaxing tendons, and activating blood, as well as relieving superficies and dispelling cold. Aim of the review: This review aims to summarize the traditional use, phytochemistry, and modern pharmacological use of Apiaceae medicinal plants (AMPs), highlight the effect of bolting and flowering (BF) on yield and quality, and provide a basis for controlling the BF. Materials and methods: All literatures involved in AMPs were searched using various online databases (e.g., PubMed, Web of science, Google Scholar, Springer, and CNKI). Additional information was collected from ethnobotanical literature focusing on herbs from Flora of China and local herbal classic literature. Result: A total of 228 AMPs have been recorded to be used as TCMs, with 6 medicinal parts (i.e., the whole plants, rhizomes and/or roots, stems, leaves, fruits, and seeds) categorized, 72 traditional uses (e.g., relieving pain, dispelling wind, and eliminating dampness) enriched, 62 modern pharmacological uses (e.g., anti-inflammatory, antioxidative, and antitumor activities) enriched, and 5 main kinds of metabolites (i.e., polysaccharides, alkaloids, phenylpropanoids, flavonoids, and terpenoids) categorized. Based on the influence level of BF on the yield and quality, 38 rhizomatous AMPs are categorized into 3 classes including: significantly affected, differently affected to some extent, and no significantly affected. Although the mechanism of BF inducing the rhizome lignification has been revealed to some extent, and several attempts have been made to control the BF, especially in Angelica sinensis, the problem of BF has not been solved in the practical production. Conclusions: So far, the traditional use of the 228 AMPs has been recorded, while the phytochemistry and modern pharmacological researches are still limited, thus, it is a treasure to find out new therapeutic agents. Since the BF regulated by internal factors and external factors have been demonstrated, and several key genes involved in BF have been identified, thus, it is available to control the BF by planting with standard techniques and innovating new cultivars using the CRISPR/Cas9 gene editing system. This review will provide useful references for the exploration and utilization, as well as the improvement of yield and quality of AMPs.
