Fatty Acid, Sugar and Vitamin Contents in Rose Hip Species

Abstract

The content of oleic and linoleic acids, glucose, fructose, sucrose, maltose, vitamin C and E (alpha and delta-tocopherol) was determined in seeds and fruits of Rosa iberice, Rosa canina, Rosa villosa, Rosa dumalis and Rosa pisiformis. The highest level of the compounds in fruits was determined as follows: linoleic acid in R. dumalis (3.150 mu g/g), oleic acid in R. canina (0.57 mu g/g), delta-tocopherol in R. dumalis (10. 12 mu g/g), alpha-tocopherol in R. pisiformis (17.60 mu g/g), vitamin C in R. canina (2855.33 mu g/g), fructose in R. dumalis (18.44 mg/g), glucose in R. dumalis (10.04 mg/g), sucrose in R. canina (5.61 mg/g) and maltose in R. dumalis (1.92 mg/g). The highest level of the compound in seeds was also determined and sequenced as follows: linoleic acid in R. canina (3.97 mu g/g), oleic acid in R. dumalis (10.50 mu g/g), delta-tocopherol in R. canina (7.15 mu g/g), alpha-tocopherol in R. iberice (11.01 mu g/g), vitamin C in R. iberice (952.10 mu g/g), fructose in R. pisiformis (17.20 mg/g), glucose in R. iberice (9.83 mg/g), sucrose in R. dumalis (14.96 mg/g) and maltose in R. canina (2.46 mg/g).
