“…The vitamin C content of the product was 15.6 mg/day, which is about 21% of the recommended daily intake for adults in Finland (Finnish National Nutrition Council, 2005). The vitamin E and carotenoid content of the product was small compared with the recommended intakes (Finnish National Nutrition Council, 2005) and the daily dose contained oil and unsaturated fatty acids less than used in previous studies reporting positive effects of sea buckthorn oil (Yang et al, 1999;Johansson et al, 2000).…”

“…The oil content of the product was analyzed gravimetrically using a chloroform-methanol extraction method (Tiitinen et al, 2005). The fatty acids of the oil were esterified using a boron trifluoride method (Å gren et al, 1992) and the fatty acid methyl esters were analyzed by gas chromatography (Yang et al, 1999). The carotenoids were analyzed by the MTT Agrifood Research Finland (Jokioinen, Finland) chemistry laboratory using an in-house HPLC-UV/VIS method.…”

“…Although the CC is usually a selflimited illness of short duration, it causes considerable costs in terms of absence from work, visits to health care providers and the amounts of drugs prescribed (Puhakka et al, 2000;Heikkinen and Järvinen, 2003). Sea buckthorn (Hippophaë rhamnoides L.) berries have traditionally been used in Eastern medicine and studies indicate that sea buckthorn has immunomodulatory properties and positive effects on health (Yang et al, 1999;Johansson et al, 2000;Eccleston et al, 2002;Geetha et al, 2002;Yang and Kallio, 2002;Dorhoi et al, 2006). To our knowledge no clinical trials have been conducted to study the efficacy of sea buckthorn in prevention and treatment of the CC.…”

Objective: To study the effect of sea buckthorn berries on the number and duration of common cold (CC) infections. As secondary objectives the effects on digestive and urinary tract infections (DTI, UTI), and serum C-reactive protein (CRP) concentrations were also investigated. Subjects: A total of 254 healthy volunteers were randomly assigned to receive sea buckthorn or placebo product during the study, which 233 of them completed. Results: There were no significant differences in the number or duration of CC or DTI between groups (CC: relative risks (sea buckthorn vs placebo) for the number and duration were 1.15 (95% CI 0.90-1.48) and 1.05 (95% CI 0.87-1.27), respectively). In the sea buckthorn group, as compared to the placebo, the serum CRP concentrations decreased significantly (difference in median change À0.059 mg/l, P ¼ 0.039). The number of UTI was too small to draw solid conclusions, but the results indicate the subject merits further investigation. Conclusion: Sea buckthorn berries did not prevent CC or DTI. However, a reductive effect on CRP, a marker of inflammation, and a risk factor for cardiovascular diseases, was detected.

“…The fatty acid composition of nonsupplemented MRS growth medium also was analyzed (2,26) (Table 1). Even though MRS medium is known (as well as shown) to possess unsaturated fatty acids (e.g., oleic acid, in the form of Tween 80), this medium was selected for this study because Tween 80 has been shown to be an essential growth factor for lactobacilli (16).…”

Most probiotic lactobacilli adhere to intestinal surfaces, a phenomenon influenced by free polyunsaturated fatty acids (PUFA). The present study investigated whether free linoleic acid, ␥-linolenic acid, arachidonic acid, ␣-linolenic acid, or docosahexaenoic acid in the growth medium alters the fatty acid composition of lactobacilli and their physical characteristics. The most abundant bacterial fatty acids identified were oleic, vaccenic, and dihydrosterculic acids. PUFA, especially conjugated linoleic acid (CLA) isomers and ␥-linolenic, eicosapentaenoic, docosahexaenoic, and ␣-linolenic acids, also were identified in lactobacilli. When lactobacilli were cultured in MRS broth supplemented with various free PUFA, the incorporation of a given PUFA into bacterial fatty acids was clearly observed. Moreover, PUFA supplementation also resulted in PUFA-dependent changes in the proportions of other fatty acids; major interconversions were seen in octadecanoic acids (18:1), their methylenated derivatives (19:cyc), and CLA. Intermittent changes in eicosapentaenoic acid proportions also were noted. These results were paralleled by minor changes in the hydrophilic or hydrophobic characteristics of lactobacilli, suggesting that PUFA interfere with microbial adhesion to intestinal surfaces through other mechanisms. In conclusion, we have demonstrated that free PUFA in the growth medium induce changes in bacterial fatty acids in relation to the regulation of the degree of fatty acid unsaturation, cyclization, and proportions of CLA and PUFA containing 20 to 22 carbons. The potential role of lactobacilli as regulators of PUFA absorption may represent another means by which probiotics could redirect the delicate balance of inflammatory mediators derived from PUFA within the inflamed intestine.

“…Beneficial effects of sea buckthorn fruits have been documented through in vitro studies, animal trials and clinical intervention studies. Thus sea buckthorn pulp oil can inhibit platelet aggregation (Johansson et al 2000), improve atopic dermatitis (Yang et al 1999) and alleviate symptoms connected with dry eyes (Larmo et al 2010) in humans. Sea buckthorn puree can lower the plasma high-sensitivity c-reactive protein level (Larmo et al 2008), which is a marker for inflammation and a risk factor for cardiovascular disease.…”

Content of total phenolic compounds and antioxidant capacity (FRAP) were investigated in the leaves of three sea buckthorn (Hippophaë rhamnoides L.) cultivars: 'Otradnaja', 'Gibrid Pertjika' and 'Ljubitelskaja', at different dates. In addition, major phenolic compounds (catechin, kaempferol, quercetin, epigallocatechin, kaempferol-3-O-glucoside, quercetin-3-O-galactoside, isorhamnetin-3-O-glucoside, rutin, gallic acid, procyanidin monomer glycoside, procyanidin dimer aglycone and hydrolyzable tannins I-III) were determined in 'Ljubitelskaja'. Antioxidant capacity and the content of total phenolic compounds fluctuated during April, May and June, and then increased until the end of July, when the highest values were observed. Total phenolic compounds were strongly correlated with FRAP. Levels were generally higher in 'Ljubitelskaja' than in 'Otradnaja' and 'Gibrid Pertjika'. In 'Ljubitelskaja', hydrolyzable tannins I-III occurred in higher amounts than did any of the other studied phenolic compounds. The developmental stage of the leaves (harvesting date) had a strong influence on content of phenolic compounds and should be carefully considered when harvesting sea buckthorn leaves for different purposes.
