Present situation and development strategy of Alpinia oxyphylla / 中国中药杂志

@#Alpinia oxyphylla is mainly produced in Hainan,and also one of the four famous traditional Chinese medicines in South China with increasing importance in traditional Chinese medicine industry. Field surveys and literatures show that A. oxyphylla has widely used as a medicinal and edible plant,it is an important raw material for many Chinese patent medicines,health products and food,with a long history of artificial cultivation and application. The future development is prospected on health market. But A. oxyphylla industry has faced a lot of problems,including unreasonable planting layout,lack of good varieties,imperfect seed breeding system,low level of standardization,inconsistent quality of medicinal materials,low level of industry,and so on. The suggestions for sustainable development are listed below.First,it is essential to strengthen the research on the basis and application technology of A. oxyphylla,speed up the selection and breeding of improved varieties,and popularize standardized cultivation techniques. Secondly,it is important to strengthen the research on quality standards,improve the quality evaluation system of medicinal materials. Thirdly,it is necessary to take full advantage of the functional components to develop functional products with Hainan characteristics,find out the unique product characteristics of A. oxyphylla,build a famous brand and improve the product competitiveness in the market. It is also important to strengthen policy support and industrial supervision,promote the healthy and rapid development of A. oxyphylla industry.

Effect of Different Processing Methods on Types and Contents of Chemical Constituents in Codonopsis Radix from Shanxi / 中国实验方剂学杂志

Objective:To establish the HPLC fingerprint of raw products,rice-processed products and honey-processed products of Codonopsis Radix from Shanxi,and establish determination of their chemical constituents,which was used to analyze the changes of types and contents of chemical constituents in Codonopsis Radix from Shanxi before and after processing. Method:Agilent ZORBAX SB-C18 column(4.6 mm×250 mm,5 μm) was adopted,the separation process was carried out using a binary gradient elution system composed of 0.5% phosphoric acid aqueous solution and acetonitrile,the column temperature was 30℃ and the detection wavelength was 220 nm. Result:Compared with the corresponding reference fingerprint,the similarities of HPLC fingerprint of 10 batches of raw products and processed products were >0.90.In raw products,rice-processed products and honey-processed products of Codonopsis Radix from Shanxi,the contents of lobetyolin were (0.33±0.049),(0.24±0.034),(0.18±0.047) mg·g-1,the contents of atractylenolide Ⅲ were (0.20±0.046),(0.40±0.046),(0.31±0.060) mg·g-1,the contents of 5-hydroxymethylfurfural(5-HMF) were (0.74±0.16),(1.45±0.19),(1.54±0.12) mg·g-1,respectively. Conclusion:Different processing methods have little effect on types of chemical constituents in Codonopsis Radix from Shanxi,but have great effect on the contents of some chemical constituents.
