摘要
利用分光光度法测定了破布叶的叶、茎、果中的总黄酮含量,结果表明,破布叶叶、茎、果中的总黄酮质量分数分别为16．94％、5．15％和1．52％。回归方程为A=11．4486C-0．00543,r=0．9996。叶、茎、果的平均加标回收率分别为102．3％、97．6％和92．6％,RSD依次为1．01％、1．94％和2．76％(n=5)。本法操作简便、可行、重现性好。
The total flavonoids in leaf, stem and fruit of Microcos Paniculata L were determined by spectrophotometry at 500 nm. The linear regression equation is A =11.448 6C - 0.00543, r = 0.9996. Results was 16.94% in leaf, the average recovery was 102.3%, RSD=1.82% （n=5）; 5.15% in stem, the average recovery was 98.4 %, RSD =1.95%（n = 5）; and 1.52 % in fruit, the average recovery was 94.0 %, RSD = 2.55 %（n = 5）. The method is simple, reproducible and practicable for the determination of total flavones.
