There are four species in the genus Phytolacca in China.The roots of P acinosa and P americana have been used as a Chinese medicine for the treatment of edema, bronchitis and tumors. A new cyclic dipeptide and a mixture of other two cyclic dipeptide were isolated together with α spinasterol and α spinasteryl 3 O β D glucopyranoside from the ethanol extract of the roots of Phytolacca polyandra .On the basis of chemical and spectral evidences,their chemical structures were determined as cyclo( Pro Tyr )(1),cyclo( Ala 1 Leu ) (2) and cyclo( Ala 2 Ile)(3) respectively.Cyclic dipeptides are isolated for the first time from Phytolaccaceae.
