摘要
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.
