CHEMICAL AND NUTRITIONAL CONSTITUENTS OF SEA BUCKTHORN (HIPPOPHAE RHAMNOIDES SSP. TURKESTANICA) BERRIES FROM PAKISTAN.

Sea buckthorn (Hippophae rhamnoides L. ssp. turkestanica) is a very important multipurpose plant in areas of northern Pakistan. The berry of sea buckthorn is rich in nutrients and medicinal compounds such as vitamins, carotenoids, flavonoids, oil, carbohydrates, organic acids, amino acids and minerals. The chemical composition and nutritive value of sea buckthorn berries from eight populations from different areas of northern Pakistan were compared. The concentration of vitamin C in the berries was 250-333 mg/100 g; the seed oil was 7.69-13.7%, oil in dried pulp was 19.2-29.1% and the pytosterol content of the seed oil was 3.3-5.5%; there were 0.5-25 mg/L anthocyanins in the fruit juice. The potassium (2.8-7.2 g/kg), sodium (0.065-0.8 g/kg), calcium (0.7-1.25 g/ kg), magnesium (139-240 mg/kg), iron (40-225 mg/kg) and phosphorus (110-133 mg/kg) contents were high in dried berries. Sea buckthorn berries from Pakistan are a good source of phytonutrients and minerals. [ABSTRACT FROM AUTHOR]
