Through the survey of the local grape industry,it found out the regional distribution,scale and benefits of the grape,as well as the variety structure and cultivation management mode. It analyzed main problems in the grape production,including low degree of organization,concentrated maturity,low rate of good fruit,small cultivation scale,and low labor-saving and high-efficiency cultivation technologies. On the basis of the development status,it came up with pertinent recommendations,including optimizing the variety structure,implementing standardized management,strengthening construction of sightseeing parks,promoting integration of primary and tertiary industries,and developing the gardening experience,to promote healthy and sustainable development of the grape industry.展开更多

Methods： In this study, a simple and efficient high-performance liquidchromatography （HPLC） method integrating with chemometric analysis and spectrum-antitumor effect relationship wasdeveloped for discrimination between two species of Mylabris： Mylabris phalerata Pallas （MP） and Mylabris cichoriiLinnaeus （MC）. Results： In the fingerprint analysis, 14 characteristic peaks were selected to assess the differencesbetween MP and MC using the similarity and pattern recognition analysis using PCA and OPLS-DA. The HPLCchromatograms of samples from 10 regions of China showed differences between MP and MC, and 7 characteristicchemical markers were found. In the spectrum-antitumor effect relationship analysis, 4 activity markers played a vitalrole in decreasing the IC50 and might be the antitumor components of Mylabris by grey relational analysis andmultivariate linear regression analysis. The chemometric analysis in combination with spectrum-effect relationshipresults indicated that peaks 2 （cytosine）, 4 （unknown） and 14 （unknown） were important differential markers fordistinguishing the two species of Mylabris. Conclusion： The method is applicable, credible and more efficient todiscriminate MP and MC, and will offer a new way for facilitating quality control of insect medicines.展开更多
