摘要
本实验以四川境内3种石斛属植物为材料,测定其总生物碱、石斛多糖的含量并研究分布规律。结果表明,各个部位有效成分的分布与种质、采摘时间、干燥方法、生长年限有直接关系：其中金钗石斛总生物碱含量最高,细茎石斛多糖含量最高;石斛也可春季采收;石斛干燥加工以高温杀青后60℃烘干为宜;细茎石斛采收以3~4年为宜。以此为依据可探索石斛野生种质资源筛选,为石斛药材人工规模化种植作理论基础。
Taken three different species Dendrobium plants as materials,the total alkaloid and polysaccharide were determined to study the distribution key.The result showed the distribution of fundamental ingredient was related with the harvest time,drying methods,and so on.The dendrobium nobile had the most total alkaloid content and the dendrobium moniliforme had the mostpolysaccharide content.The optimum harvest period was for 3-4 years.
