Two new phenethanol glycosides from Ligustrum robustum

Abstract 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), 1 H NMR, 13 C NMR, HMQC, and HMBC spectra for the first time.
