【摘要】[Objectives] To make a preliminary study of the effects of the fertilizer application and transplantation from Qichun County, Hubei Province, China, to neighbouring area on the chemical substance contents and moxa yield of Artemisia argyi leaf in Qichun(AALQ). [Methods] The content of the total flavonoids in AALQ was determined by UV-Vis spectrophotometry with apigenin as reference substance. The contents of volatile oil and tannins were determined by the methods in Chinese Pharmacopoeia(2015 edition). The moxa yield was detected by the self-developed method of grinding and sifting with high-speed pulverizer. [Results] Whether applying cake fertilizer, or compound fertilizer after applying barnyard manure, the contents of total flavonoids and tannins in AALQ were reduced in varying degrees, and the content of volatile oil was changed, which had adversely affect the accumulation of effective substances in the leaves of medicinal A. argyi as a whole. The contents of related chemical substances and moxa yield of A. argyi planted in the neighbouring Xishui County from Qichun, Hubei Province were relatively high. [Conclusions] The contents of effective substances and moxa yield of AALQ were significantly reduced as a whole when applied fertilizer in planting, especially after the application of barnyard manure, compound fertilizer was added. The quality of A. argyi leaf would not be adversely affected if it was transplanted from Qichun County, Hubei Province, which is the genuine producing area, to nearby areas with similar ecological environment.
