Analysis and Evaluation of Nutritional Component of Platycodon grandiflorus in Three Main Producing Areas
摘要
Abstract
Objective:To analyze and evaluate the nutritional components of three main producing areas of Platycodon grandiflorum in Inner Mongolia, Chifeng, Shandong, Boshan, Anhui Bozhou and Taihe.Methods:The contents of crude fiber, polysaccharide, protein, mineral elements and amino acid were determined respectively by the gravimetric method, the phenol-sulfuric acid colorimetry, Micro-Kjeldahl method, atomic absorption spectiometry, acid hydrolysis-automatic amino acid analyzer.Results:The crude fiber content of P.grandiflorum ranged from 6.9％ to 9.1％, which was the highest in Bozhou, Anhui province, and was significantly higher than that from other producing areas;the polysaccharide content of P.grandiflorum ranged from 18.1％ to 23.1％, and the polysaccharide content of P.grandiflorum in Boshan, Shandong province was significantly higher than that from other producing areas;the crude protein content of P.grandiflorum ranged from 6.6％ to 14.1％, Bozhou, Anhui province the production area was significantly higher than that from other producing areas.P.grandiflorum was rich in arginine, proline, glutamic acid and lysine, which accounted for nearly 70％ of total amino acids.The content of mineral elements in P.grandiflorum from different producing areas was obviously different.The contents of mineral elements in P.grandiflorum from Boshan, Shandong Province were lower than those from other areas except that of zinc element.Conclusion:P.grandiflorum is a functional food rich in polysaccharides, mineral elements and high fiber.Due to the significant differences in nutrient composition among P.grandiflorum from different habitats, it is necessary to select the suitable habitats for exploiting P.grandiflorum resources.关键词
