Phytochemical investigations of the n-butanol soluble sub-fraction of the methanolic extract of Galinsoga parviflora Cav. has led to the isolation of two new glucosides named as parvisides A (1) and B (2). Their structures have been assigned on the basis of their spectral analysis including 1D and 2D NMR techniques.
