Two new phenethanol glycosides from Ligustrum robustum

Two new phenethanol glycosides, named ligurobustoside P (1), ligurobustoside Q (2) have been isolated from the leaves of Ligustrum robustum, together with the known compound angoroside A (3) which was firstly isolated from this species. The structures of the two new phenethanol glycosides (1–2) were elucidated by a combination of high-resolution electron ionization mass spectrometry (HR-ESI-MS), 1H NMR, 13C NMR, HMQC, and HMBC spectra for the first time.
