Six new ergostane glycosides, designated as petunioside A, petunioside
B, 24-epipetunioside B, petunioside C, 24-epipetunioside C and petuni
oside D, were isolated from the methanolic extract of the fresh aerial
parts of Petunia hybrida. Their structures were determined by means o
f spectroscopic analysis and single crystal X-ray analysis.
