摘要
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,^（13）C NMR,HMQC,and HMBC spectra for the first time.
