[Research progress on chemical constituents and their differences between sea buckthorn berries and leaves]

Sea buckthorn berries and leaves are two medicinal parts derived from the same primitive plant,mostly used as ethnic medicine,which have a long history in Mongolian and Tibetan. This paper reviews the studies on the chemical composition and differences between sea buckthorn berries and leaves. They have the same or similar composition and content of flavonoids,triterpenes,steroids,organic acids and volatile oils,also have some differences. The main differences are as follows: the flavonoids content in the sea buckthorn leaves is greater than that of the sea buckthorn berries,but the species of flavonoids in the berries are higher than leaves. The species and content of steroids and organic acids in the berries are higher than that of the leaves. The berries contain abundant volatile oil,and the leaves contain many phenolic compounds. Finally,the main problems and the prospect of the next research are put forward.
