目的 对比铁皮石斛与其常用替代品在品质方面的差异.方法 采用苯酚-硫酸法与重量法,研究对比了西双版纳地区不同来源铁皮石斛及齿瓣石斛多糖含量及折干率的差异.结果 铁皮石斛的多糖含量及折干率分别为20.29%,20.16%,齿瓣石斛为16.93%,18.92%.结论 不同栽培类型的铁皮石斛存在品质差异;齿瓣石斛的野生苗品质优于组培苗.
目的 對比鐵皮石斛與其常用替代品在品質方麵的差異.方法 採用苯酚-硫痠法與重量法,研究對比瞭西雙版納地區不同來源鐵皮石斛及齒瓣石斛多糖含量及摺榦率的差異.結果 鐵皮石斛的多糖含量及摺榦率分彆為20.29%,20.16%,齒瓣石斛為16.93%,18.92%.結論 不同栽培類型的鐵皮石斛存在品質差異;齒瓣石斛的野生苗品質優于組培苗.

Objective To compare the difference of quality between Dendrobium candidum and Dendrobium devonianum.Methods Phenol-Sulphate Acid method and gravimetrict method were used to measure polysaccharides contents from Dendrobium and their weights after baking.Results The polysaccharides content and drying rate of Dendrobium candidum were 20.29%,20.16% respectively, that of Dendrobium devonianum 16.93%, 18.92% separately.Conclusion The cultivated type of Dendrobium candidum is significantly different in quality. The quality of natural seedling of Dendrobium devonianum is superior to that of tissue culture seedling.
