Fatty Acid Composition of Lipids in Sea Buckthorn (Hippophaë rhamnoides L.) Berries of Different Origins

Abstract

The oil content and fatty acid composition of berries from two subspecies of sea buckthorn (Hippophaë rhamnoides L.) were investigated. The berries of subsp. rhamnoides contained a higher proportion of oil in seeds (11.3% vs 7.3%, p < 0.01), berries (3.5% vs 2.1%, p < 0.001), and seedless parts (2.8% vs 1.7%, p < 0.01) than the berries of subsp. sinensis. Linoleic (18:2n-6) and alpha-linolenic acids (18:3n-3) comprised about 70% of seed oil fatty acids. Palmitoleic acid (16:1n-7), practically absent in the seed oil, comprised 12.1--39.0% of oil in pulp/peel and 8.9--31.0% of that in the whole berries. More linoleic acid (40.9% vs 39.1%) and less alpha-linolenic acid (26.6% vs 30.6%) was found in the seed oil of subsp. sinensis than in the seed oil of subsp. rhamnoides (p < 0.05). The proportion of palmitoleic acid was higher in the oil of berries of subsp. rhamnoides than the berries of subsp. sinensis (26.0% vs 21.5%, 0.05 < p < 0.1), but was vice versa with alpha-linolenic acid (8.8% vs 11.2%, 0.05 < p < 0.1). The proportions of alpha-linolenic acid correlated inversely with oleic and linoleic acids in the seed oil. In the oil of whole berries, the proportion of palmitoleic acid correlated negatively with the proportions of linoleic and alpha-linolenic acids.

Heterotrophy of filamentous oleaginous microalgae Tribonema minus for potential production of lipid and palmitoleic acid

“…Up to date, this fatty acid, with a variety of functions, is mainly obtained from sea buckthorn (Hippophae rhamnoides L.), which contains about 43% palmitoleic acid in its total lipid but confronts the limitation of commercialization due to its very low lipid content in buckthron pulp, low yield and poor agronomic characteristics (Wu et al, 2012;Yang and Kallio, 2001). Oils from large scale planted oil crops, such as Sunflower and Jatropha, contain less than 2% palmitoleic acid (Salas et al, 2004;Okullo et al, 2012).…”

Palmitoleic Acid Calcium Salt: A Lubricant and Bactericidal Powder from Natural Lipids

“…Palmitoleic acid C16:1 fatty acid , which is contained in plant oils from macadamia nuts 1 , hazel nuts 2 , and seabuckthorn 3 and in the sebum cutaneum of humans 4 , exhibits antibacterial activities and bactericidal properties toward S. aureus, Streptococcus salivarius, the anaerobe Fusobacterium nucleatum, Neisseria gonorrhea, and Helicobacter pylori 5 8 . This fatty acid has great potential as a bactericidal agent for cleansing products because its activity is selective: although this fatty acid exhibits strong bactericidal activity toward some harmful bacteria, as previously mentioned, it does not kill good bacterium such as S. epidermidis.…”

Characterization and identification of ISSR markers associated with oil content in sea buckthorn berries

“…This species adapts very well to harsh environments, including conditions of drought, salinity and temperatures ranging from -40° to 40°C . Bioactive oils extracted from sea buckthorn berries contain polyunsaturated fatty acids, vitamins, carotenoids and flavonol glycosides (Ranjith et al, 2006;Lehtonen et al, 2010;Li et al, 2013), although oil contents are only 6 to 12% in seeds and 1 to 6% in fresh pulp (Yang and Kallio, 2001;Ruan et al, 2007;Dulf, 2012).…”
