Hippophae salicifolia D. Don, a Fascinating Medicinal Plant: An Update on its Traditional Medicinal Uses, Ethnopharmacology and Phytochemistry

Abstract

Abstract: Hippophae salicifolia, belonging to family Elaegnaceae, is a thorny shrub, and shows actinorhizal habit. The species prefers a habitat of temperate regions in Europe and Asia. In India, it is distributed in the Himalayan region of Uttarakhand, Himachal Pradesh, Jammu and Kashmir, and the North-Eastern parts. The oil, fruits, leaves, and bark of Hippophae species have a pronounced use in ethnomedicines, nutritional food, cosmetics, nitrogen-fixing in soil, water conservation and as fuel source. The aim of this review is to provide updated, comprehensive, and classified information on the traditional uses, phytochemistry, pharmacological and toxicological research carried out on H. salicifolia. This will help researchers to explore its therapeutic potential and examine future research possibilities. The chemical composition of this shrub comprises minerals, vitamins, flavonoids, flavonoid glycosides, polyunsaturated fatty acids, sugars, carotenoids, and nucleobases. Pharmacological studies demonstrated that the extracts prepared from leaves, barks, and berries along with fixed oil of this species are useful as anti-oxidant, anti-inflammatory, anti-cancer, anti-diabetic, anti-depressant, anti-microbial, adaptogenic, and wound healing. The results of toxicity study of H. salicifolia extracts did not show any significant acute toxicity in experimental animals. Abundance of phenolic compounds, minerals, and fatty acids within the different parts of this plant prompted researchers to isolate and characterize the phytoconstituents which are responsible for its therapeutic uses.
