| 摘 要： | 利用分光光度法测定了海南木莲中的总黄酮含量,结果表明:海南木莲叶中总黄酮的质量分数为5.78%,RSD=2.62%(n=6);枝中为3.05%,RSD=2.16%(n=6).回归方程A=7.901 4c+0.002 8,相关系数r=0.999 9.本法操作简便,测定结果稳定、准确,为开发利用海南木莲药用提供了科学依据.

| Abstract: | Spectrophotometry was used to determine the flavone content in manglietia hainanensis dandy.The results were w=5.78 %(RSD = 2.62 %)in leaf and w=3.05 %(RSD = 2.16 %) in stem of manglietia hainanensis dandy.The regression equation was A=7.901 4c+0.002 8,r= 0.999 9.The method has such advantages as high sensitivity and stability. |
