Abstract

A new stereoisomeric monoterpene glycoside and five already-known compounds were isolated from the n-BuOH soluble fraction of Clematis heracleifolia leaves. On the basis of spectral data, the structures of the isolated compounds were identified as protocatechuic acid (1), ferulic acid (2), caffeic acid (3), aesculin (4), (6Z)-9-hydroxylinaloyl glucoside (5), and 9-hydroxylinaloyl glucoside (6) and these were isolated for the first time from this plant. Among these compounds, (6Z)-9-hydroxylinaloyl glucoside (5) is a newly isolated from plant source.
