摘 要 ：样品经超声提取后,在硅胶GF₂₅₄薄板上,以甲苯-乙酸乙酯-甲酸(2:3:2.2)展开,测定波长280nm,参比波长207nm,线性范围0.46～4.6μg/ml,平均回收率为98.35%,RSD=2.82%。

Abstract:Baicalin in the samples was extracted with ultrasonic wave, the extract was spotted on thin-layer plates of gelGF₂₅₄ and developed with the mobile phase consisting of toluene-ethylacetate-formic acid (2:3 : 2.2). Determinationswere carried out with Shimadzu CS-930 TLC scanner with λ_s= 280 nm and λ_R= 207 nm. The linear range was 0.46-4. 6μg/ml. The average recovery of baicalin from the samples was 98. 35 %,RSD= 2.82% .
