Status of Polygonati Rhizome industry and suggestion for its sustainable development / 中国中药杂志

ABSTRACT

Field surveys and literatures show that Polygonati Rhizome (Huangjing) was firstly recorded in Shen Nong&s Herbal Classic, and widely used as a medicinal and edible plant. It has a long history of cultivation, and the researches on chemistry have made some progress. The future development is prospected on health market. But the Polygonati Rhizome industry has faced a lot of problems, including the resource depletion, unstable quality, low-tech in cultivation and germplasm confusion, unclear of functional composition, decentralized, small scaled and primary processing products. The suggestion for sustainable development are listed below. First, the relevant researches should focused on material basis and biological mechanism of core effects. To speed up the selection and breeding of improved varieties, ensure the supply of high-quality seedlings and eliminate the unauthentic species are the most important measures. Secondly, to strengthen the conservation and rational use of wild resources, break through the key technologies of high-quality artificial cultivation on light regulation, site control, density control and precision harvesting are also very important. Thirdly, to reveal the toxicity-reducing-and-efficacy-enhancing mechanism of processing, optimize the parameters and setup the standard operating procedure are indispensable. Fourthly, that full advantage of the root, leaf, flower and fruit resources should be strengthened for enlarged health products based on the development of exact functional factors. Above all, Polygonati Rhizome could be a growing market in the future driven by the technological innovation, cultural creativity, integration of three industries, brand strategy and internet+technique.
