The paper reported that UV and IR spectrum were used to identify Alisma orientalis and A. canaliculatum. The results of determination showed that the solution of methanol extraction of A. orientalis absorbed in 204.1 +/- 0.5 nm, but which of Alisma canaliculatum absorbed in 205.7 nm and 285 nm in UV spectrum. The dry substance of water extraction of A. orientalis absorbed in 3402, 2933, 1642, 1054 and 926 cm-1 in IR spectrum. IR spectrum of A. orientalis is different from which of Alisma canaliculatum in fingerprint.
该论文报道了利用紫外光谱和红外光谱对泽泻和窄叶泽泻进行鉴别。测定结果表明，泽泻甲醇提取物溶液在紫外光谱中于204.1±0.5nm处有吸收，而窄叶泽泻的甲醇提取物溶液在205.7nm和285nm处有吸收。泽泻水提取物的干燥物质在红外光谱中于3402、2933、1642、1054和926cm-1处有吸收。泽泻的红外光谱在指纹区与窄叶泽泻的不同。
