Investigation on the Rubus idaeus L Seed Oil (Rosaceae)

Abstract

Seeds of the plant species Rubus idaeus, Rosaceae family is investigated as a source of specific oils and are determined by its physical and chemical characteristics. Plant species Rubus idaeus, known as raspberry, is widespread in Central and Eastern Europe. Well-known medicinal properties of juice and raspberry syrup, and in folk medicine commonly used raspberry leaf tea in the treatment of bronchial diseases and stomach problems. Raspberry seed oil has not tested, and are not aware of its medicinal properties. The oil from the seeds isolated raspberry green color and strong characteristic odor. The oil content ranges in the range of 8-15%. AOCS using standard methods was determined by a specific weight (0911 kg / m3), the refractive index (1.4735 at 20 ° C), acid number (1.89), saponification number (189), iodine number (139) and peroxide ( 0.22 mmol O2 / kg). Carotene content is relatively low (0.24 mg / L), and the chlorophyll content is very high (1.12 mg / L of chlorophyll and 0.63 mg / L of chlorophyll b). Is determined by gas chromatography fatty acid composition. Raspberry seed oil is characterized by an extremely low content of saturated fatty acids (4.4%) and very high content of unsaturated fatty acids (95.5) where a significant proportion of polyunsaturated fatty acids (PUFA - 85.6%). Oil seeds R. Idaeus represents a significant source of α-linolenic acid (26.4%) (18: 3 ω-3), which like the other ω-3 fatty acids are essential in building membranes of brain cells and muscle tissue of the heart. It was also proved that the oil contains a high percentage of tocopherol (358.0 mg%). Due to the high content of polyunsaturated fatty acids of this oil is likely to oxidative unstable, which require special storage conditions. Also, established oil properties determine the possibility of application in medicine and pharmacology, as a source of relatively pure oil-rich α-linolenic acid. (Google translated)
