泰山沙参属植物资源调查与营养成分分析

Investigation on the Resources and Nutritional Components of Genus Adenophora Fisch.in Taishan Mountain

目的:了解泰山沙参属植物资源现状,测定其根中脂肪、蛋白质及多糖的含量,为合理开发利用泰山沙参属植物资源提供依据。方法:采用野外实地调查法进行资源考察;分别用索氏提取法、考马斯亮蓝法和苯酚-硫酸法测定脂肪、蛋白质和多糖的含量。结果:采集的100余份标本,经鉴定为沙参属植物狭叶沙参[Adenophora gmeli-nii(Spreng)Fisch.]、石沙参(Adenophora polyantha Nakai)、杏叶沙参(Adenophora stricta Mig.)及细叶沙参(Adeno-phora paniculata Nannf.)。泰山沙参属植物狭叶沙参、石沙参、杏叶沙参和细叶沙参脂肪含量分别为2.14%～7.34%,4.27%～7.72%1,.54%～2.51%和4.98%。蛋白质含量分别为0.60～2.10 mg/g0,.80～1.89 mg/g,0.83～0.89 mg/g和1.05 mg/g,多糖含量分别为20.58%～63.21%2,7.74%～65.14%,43.14%～48.47%和45.60%。结论:泰山野生沙参属植物资源丰富,品种多、分布广、蕴藏量大,多糖含量较高,具有较大的开发前景。

Objective： Investigate the wild resources of the Genus Adenophra Fisch.in Taishan Mountain and determine the contents of fat,proteins and polysaccharide to provide foundation for its utilization and protection.Methods： Use the field investigation to investigate the resources.Soxhlet method was used to determine the content of fat.Bradford method was employed to measure proteins content.Polysaccharides content was determined by the phenol-sulfuric acid method.Results： More than 100 samples collected were identified as Adenophora gmelinii（Spreng.） Fisch.,Adenophora polyantha Nakai,Adenophora stricta Mig.and Adenophora paniculata Nannf.and their fat contents were 2.14% to 7.34%,4.27% to 7.72%,1.54% to 2.51% and 4.98%,respectively.Their proteins contents ranged from 0.60 to 2.10 mg/g,0.80 to 1.89 mg/g,0.83 to 0.89 mg/g and 1.05 mg/g,respectively.The polysaccharides contents varied from 20.58% to 63.21%,27.74% to 65.14%,43.14% to 48.47% and 45.60%,respectively.Conclusion： The wild resources of the Genus Adenophora Fisch.in Taishan Mountain is rich and have great exploitation prospects.
