摘　　要：采用Morgan-Elson法追踪测定广西甜茶抗过敏活性成分。研究结果表明:广西甜茶中含有抗过敏成分,抗过敏成分经过超滤膜粗纯化后,得到样品3;经过凝胶层析精制后,得到样品3g。样品3和样品3g经过薄板层析、紫外光谱、红外光谱定性及高效液相色谱检测,发现广西甜茶中抗过敏有效成分为水解型鞣花鞣质,分子量范围为10～30kD,化学构型为C6-C3-C6。Antiallergic active components of sweet tea were guided by Morgan-Elson method, The result shows that sweet tea of Guangxi has antiallergic components, sample 3 can be isolated after being elementary purified by ultrafiltraUon membrane and sample 3g can also be obtained after being further purified by gel chromatograph. By using the method of TLC and UV and IR and HPLC, we proved that antiallergic active components of sweet tea are hydrolysable ellagitannin. The molecular weight of sample 3 is 10-30kD and configurational base unit is C6-C3-C6.
