摘要
通过比较不同生长年限人工种植"桑黄"及野生"桑黄"的生物学特性,从而确定人工种植"桑黄"的最佳采收期。取1年生、2年生、3年生、4年生、5年生人工种植"桑黄"及野生"桑黄"子实体,使用紫外-可见光分光光度法测定比较人工栽培不同生长年限"桑黄"子实体以及野生"桑黄"子实体的多糖、总黄酮、总三萜含量。2年生人工种植的"桑黄"子实体多糖含量为2.216 mg/g,总黄酮含量为190.067 mg/g,三萜含量为0.6045 mg/g,3种有效成分的含量均优于野生"桑黄"子实体。可以初步将"桑黄"的采收期定为2年。
Through comparative study on the biological characteristics between the cultivated with different age limits and the wild sanghuang, to determine the best harvest time of cultivated Sanghuang. The content of polysaccharide, total flavone, total triterpenoids was compared by using UV-V between the cultivated Sanghuang with one age, two ages, three ages, four ages, five ages limits and the wild Sanghuang. The content of polysaccharide, total flavone, total triterpenoids of cultivated Sanghuang with two ages respectively was 2.216 mg/g, 190.067 rag/g, 0.6045 mg/g, was higher than the others. So we can preliminary identify the best harvest time of cultivated Sanghuang was two ages.
