SEPARATION AND IDENTIFICATION OF THE LLUNGIANIN A AND B FROM THE ROOT OF PIMPINELLA THELLUNGIANA WOLFF

Two compounds were isolated from the roots of Pimpinella thellungiana wolff. On the basis of spectral analysis (UV,IR,MS, ¹HNMR, ¹H-¹H COSY, ¹³CNMR, ¹H-¹³C COSY,DEPT), they were identified as 2-(1-ethoxy-2-hydroxy) propyl-4-methoxyphenol(I); 2-(1-ethoxy-2-hydroxy) propyl-4-methoxyphenyl-2-methyl butyrate(II). They are new compounds named the llungianin A and B. Pharmacological tests showed that they have some hypotensive effects.
