| Abstract: | A natural compound, glucocochlearin, was isolated from the aerial parts of 10 different Cochlearia species. The purification of this compound was achieved through HPLC. The identity of the product was established mainly on the basis of spectroscopic NMR (1H, 13C, COSY, TOCSY, HMQC, HMBC, J-MOD) and high resolution mass spectroscopy data. This compound can be considered as a chemomarker of the genus Cochlearia. |
