【Abstract】 Seabuckthorn (Hippophae L.), a deciduous shrub or tree, is widely distributed in the temperate zone of Asia and Europe and in the subtropical zone of Asia at high altitudes. There are 4 species and 9 subspecies in this genus of which 4 species and 5 subspecies are to be found in north, north-western and south-western China. It is considered that China is probably the main center of origin, evolution and distribution of Hippophae. the berries of 3 species are very rich in vitamin C: H. rhamnoides ssp. sinensis, 800~1300mg/100ml; H. rhamnoi-des ssp. Ytinnanensis,800~1200mg/100ml; and H. salicifolia, 1500~1700mg /100ml. These are currently being used to make soft drinks. The seeds of H. rhamnoides ssp. turkestanica, H. rhamnoides ssp. mongolica, H. rhamnoides ssp. gyantsensis,H. thibetana and H. neurocarpa are rich in oil content, being from 9.8% to 19.5%. They are thus a good source of oil. The plant of Hippophae shows high ability in fixing atmospheric nitrogen. With their extensive root system, they are valuable in controlling soil erosion.更多还原
