A new triterpene glycoside 1 was isolated together with the five known triterpene glycosides 2-6 from the cultures of Phytolacca americana. The structure of 1 was elucidated by analysis of spectroscopic data and comparison of its NMR data with those of 2-7 and chemical degradation.

Key words Phytolacca americana; triterpene glycoside; cell culture
