Introduction: In last years, many farmers, manufacturers and reserchers have paid attention to the seabuckthorn cultivation, production and investigation due to seabuckthorn berry’s value and possitive effect on human body. As is known, the fruits of seabuckthorn are used for the production of oil and juice [1,2] in Mongolia. Thereby, the large volume of waste residue material from seabuckthorn, such as pulp, skin and seed residues from juice and oil extraction, could be developed into a biologically activity product.We studied some chemical composition of seabuckthorn waste residue. Waste residue was sampled from Monos Food Co.,Ltd. Moisture content was determined by gravimetric method, the ash content was determined by incinerating in a muffle furnance at 5500C, vitamin C and total carotinoidwere determined by method of Mongolian National Pharmacopeia [3]. Moisture was 71.65%, total mineral element (ash) was 4%, acidity was 0.26%, Vitamin C was 0.03 mg% and total carotinoid was 0.02 mg%. Our next study will utilize seabuckthorn waste to develop bioactive product and food additive.References:1.
