[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.
