摘要: 采用折干率法测定不同生长期短葶山麦冬的产量;采用苯酚硫酸法测定短葶山麦冬药材中麦冬多糖的含量,并计算总量。考查比较短葶山麦冬的产量和多糖含量的动态变化,结果表明5月中旬短葶山麦冬的产量和多糖含量积累达到最高,可以确定5月份为短葶山麦冬药材的最佳采收期。

Abstract: This study was conducted to determine the best harvest time for Liriope muscari(Decne.) Baily.Using the drying rate as an index,the yield of L.muscari(Decne.) Baily was determined every 15 days.The polysaccharide content was measured by using phenol sulfuric acid method.The result showed that the yield and total polysaccharide content in the tubers of L.muscari(Decne.) Baily were at their highest levels in mid-May.Therefore,it was recommended as the optimum harvest time.
