The Influence of Market Risk on Planting Industry of Codonopsis pilosula(Franch.) Nannf. Based on the Relation of Different Growing Years and Yield, Quality of Codonopsis Radix / 中国药学杂志

ABSTRACT

OBJECTIVE: To study the influence of different growing years on the yield, quality and benefits of Codonopsis Radix for providing the basis for guiding the planting and obtaining relatively stable economic benefits. METHODS: The Codonopsis pilosula(Franch.)Nannf. were cultivated year by year by field plot completely randomized trial for measuring the yield and quality of 1 year to 5 year Codonopsis Radix. The Codonopsis Radix was harvest in the fifth year at the same time and the yield of plot was measured for the evaluating yield of per Mu. Quality of character and the content of extract of Codonopsis Radix were analyzed and measured according the methods recorded in 2015 edition Chinese Pharmacopoeia. The content of Codonopsis pilosula polysaccharide was measured by UV spectrophotometry. The contents of lobetyolin and atractylenolide III were determined by method of HPLC. Taking yongxinxiang as an example to analyze the efficiency and market risk of growing Codonopsis pilosula(Franch.)Nannf.. RESULTS: The yield of Codonopsis Radix increases along with increase of growing years. The size is positively correlated with the length of growth, and the texture is on the contrary. There is a negatively relationship between content of Codonopsis pilosula polysaccharide, extract and the increase of growing years. And there is a positive correlation between contents of lobetyolin, atractylenolide III, output value of field and the increase of growing years. However, the economic benefit was due to the price in market. CONCLUSION: It is suggested that the cultivation years of Codonopsis pilosula(Franch.)Nannf. should be extended for effectively avoiding market risks on the premise of guaranteeing quality because of the economic benefit of Codonopsis Radix is greatly influenced by market fluctuation.
