  • Title: [The identification of Alisma orientalis and Alisma canaliculatum by UV and IR spectrum].
    Author: Wu Q, Wang L, Duqian.
    Journal: Zhong Yao Cai; 2002 Dec; 25(12):871-4. PubMed ID: 12685345.
    Abstract:
    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.
