Supporting information for: Cordiasecosides G-J, 9,10-Seco-29-norcycloartane glycosides isolated from Cordia lutea and their antibacterial activities.

Four new compounds, Cordiasecosides G-J were isolated. Their structural assignment is based on NMR and MS analysis.

Their stereochemistry is confirmed by molecular modelling studies using DFT-NMR calculations. Their antibacterial and toxicity against celle lines was evaluated. This set of data contains 1D and 2D NMR spectra for Cordiasecosides G-J, detailed results of DFT calculations and NMR modelisations for Cordiasecoside I including geometries, total energies, enthalpies and Boltzmann distribution; experimental and calculated 13C chemical shifts in the chloroform PCM continuum model (SMD), and RMSD value; calculated 1H chemical shifts and coupling constants for the major conformers ; 1H NMR spectrum simulated at 300 MHz using MestReNova software, purification diagram for Cordiasecosides G-J , detailed protocols for MPLC used for purification of Cordiasecosides G-J, dose-response curves for Cordiasecosides G-J tested against RAW cells 264.7
