采用薄层一荧光法测定丹参药材中丹参酮ⅡＡ的含量。使用硅胶Ｇ薄板，展开剂为苯一醋酸乙酯（９：１）。激发波长为３３５ｎｍ，发射波长为４００ｎｍ，在１０－６，１０－７，１０－８ｇ／ｍｌ３个数量级均呈良好的线性关系，回收率为９８．７％。
Determination of tanshinone Ⅱ A in Radix Salviae Miltiorrhizae by TLC-fluorescence method. Using silica gel G plate, developing agent is benzene ethyl acetate (9: 1). The excitation wavelength was 335 nm and the emission wavelength was 400 nm. There was a good linear relationship between the three orders of magnitude of 10-6, 10-7 and 10-8 g / ml with the recovery of 98.7%.
