OBJECTIVE@#To develop a qNMR method for quantitative analysis of triacylglycerols in fruit oil of Hippophae rhamnoides (seabuckthorn, SBT) and analyze commercial samples of SBT oils using GC-MS and FTIR.@*METHODS@#SBT fruit oil (IPHRFH) was extracted with hexane and the triglyceride (TAG) was isolated by vacuum liquid chromatography. Six different branded SBT oils purchased from e-commerce suppliers (Amazon) and in-house prepared SBT oil was analyzed by qNMR and fatty acyl composition of TAGs determined by using NMR. In-house oil was also analysed by GC-MS and FTIR spectroscopy.@*RESULTS@#The qNMR results showed that the oil contained 80.3% of triacylglycerol (TAG). The SBT oil TAGs comprised of linolenate 6.6%, palmitoleate/oleate 65.4%, and total saturated fatty acyl chain including palmitate 28% as determined by qNMR. GC-MS analysis revealed that the major acyl functionalities present in the TAG were palmitoleic acid 36.5%, oleic acid 12.9%, palmitic acid 21.2%, and linoleic acid 18%. Of the six commercial samples analyzed, samples from only one supplier (SW) were fruit oil; All others were the seed oils or mix of fruit oil and seed oil. The labels for samples except for the SW did not indicate whether it was fruit oil or seed oil.@*CONCLUSION@#The results suggest that SBT oil should be analyzed by combination of GC-MS, FTIR and qNMR for factual content of free fatty acid or TAGs, which are chemically different in nature and affect the quality of oil. GC-MS showed the content of omega free fatty acids after hydrolysis, while qNMR and FTIR showed the content of TAGs. The major acyl functionalities found in SBT fruit oil TAGs are palmitoleate/palmitate/oleate, while linoleate and linonelate make up a minor fraction. Furthermore, analysis of commercial samples showed discrepancies between label claims and actual content.

Aim: To study the effects of orally administered mixture of Hippophae rhamnoides leaf and marc extracts (HLM) on health parameters of newborn calves. Study Design: Starting from birth day 0 (D0) till day 15 (D15) the extract of HLM was given orally to newborn calves before feeding them milk at an increased dosage from 5 to 8 ml/calf/ two times a day for prophylaxis of nutritional diarrhoea. The calves were clinically examined and weighed. Biochemical and morphological analyses of blood were determined. Place and Duration of Study: Clinical institute, Faculty of Veterinary Medicine and the Institute of Horticulture at Latvia University of Agriculture, Jelgava, Latvia; within one year. Methodology: HLM was prepared and chemically analysed.The control (C) and experimental (E) group - each consisted of 10 newborn calves. Clinical examination of calves was performed every day. Calves were weighed on D0, D15, D30, venous blood samples for biochemical and haematological analyses were collected on D1, D10, D15, D30. Data were analysed using software program SPSS 17.5. Results: Tannin content decreased by 33.14% in HLM after addition of polyethylene glycol. In E, there was a better thermoregulation on D1. Diarrhoea incidence was fewer in E group (3 calves) than in C group (5 calves) and diarrhoea started later in E group (D6) compared to C group (D4). Daily weight gain on D0-D15 was significantly higher in E (473.1+/-35.0 g/day) than in C (386.6+/-36.9 g/day) (P= .05) and it correlated (r =- .625) with serum haptoglobin (Hpt) concentration. In E, Hpt significantly decreased on D10 and D15, compared with C. In E there was induced reduction of lymphocytes’ count in blood- on D30 it was 27.9±6.5 x109/μL (P< .01), lower than in C- 64±2.1 x109/μL. Conclusion: HLM as feed additive can reduce diarrhoea incidences in calves, promote growth rate, reduce Hpt concentration and lymphocytes’ count in blood.

Objective The oligomeric and polymeric proanthocyanidins in different fractions from Hippophae rhamnoides seeds were investigated. Methods The monomeric and oligomeric fractions were analyzed by HPLC/ESI-MASS detection. The polymeric proanthocyanidins were fractionated by Sephadex LH-20 column chromatography and their chemical constructures were studied by acid-catalysed degradation in the presence of benzyl mercaptan. Results Four monomers were identified as catechin, epicatechin, gallocatechin, and epigallocatechin. Eight dimers including three dimeric procyanidins and one dimeric prodelphinidin, and four mixed dimers were detected and their structures were partly elucidated by the detection of the pseudomolecular ion and main ion fragmentations. The results also showed that polymers to be highly heterogenous with catechin, epicatechin, gallocatechin, and epigallocatechin all being components of both the extension and the terminal units. The extension units were mainly gallocatechin, whereas the terminal units were mainly gallocatechin and epigallocatechin for all fractions. The proanthocyanidins with a mean degree of polymerization (mDP) of 9.1, 13.2 and 17.0 represented the three major polymeric fractions. Conclusion Proanthocyanidins of H. rhamnoides seeds, predominantly being of prodelphinidin-type, are remarkably different from that of grape seeds.

Résumé
TFH was isolated from the fruits of Hippophae Rhamnoides L. A study was made cf the effects of TFH on the immune reaction in animals. TFH ( 5.0mg/kg? d-1 sc?6d)remarkably enhanced the pha-gocytic activity of peritoneal exudate macrophages. The content of lysozyme in mice ( TFH 2mg/kg?d-1 ip?7d) & serum complement in guinea pig also were remarkably elevated. TFH caused significant increases of quantitative hemolysin of SRBC ( QHS ) in normal mice. At the dose of 2mg/kg?d-1 ip?8d TFH increased the production of hemolysin serum and agglutinin in normal mice as well as in immunodepressed mice induced by cyclophosphamids. TFH ( 6.25-50mg/L) markedly enhanced Con A-induced lymphocyte proliferation of mouse spleen cells in vitro. These results suggested that TFH had certain immunopotentiation in animals.
Résumé
From Hippophae rhamnoides L.oil free seed, acylated ?-sitosterol ?-D-glucoside was isolated.By alkaline hydrolysis, acylated steryl glucoside yielded ?-sitosterol-?-D-glucoside and fatty acids which were identified as palmitic, stearic, oleic, linoleic, linolenic and decadecylenic acids.These results suggest that acylated steryl glucoside may be esterified forms of ?-sitosterol-?-D-glucoside which was identified by means of physicochemical properties, spectral analysis and synthesis, ?-sitosterol ?-D-glucoside in relatively small doses (i. e. 12mg/kg) was found to be an effective agent in the treatment of acetic acid-induced chronic ulcer in mice.

Objective: To study the effect of flavonoids from seed residues of Hippophae rhamnoides L.( FSH) and Hippophae rhamnoides L. oil(HRO)on serum lipid in female rats with obesity. Methods Female aged rats with obesity were given FSH and HRO by oral administration for 6 w. Serum triglyceride(TG) and cholesterol(TC) were determined every 2 w. The serum free fatty acid (FFA), high-density lipoprotein cholesterol (HDL-C),body weight and Lee’s index were measured after 6 w. Results: Serum TG and FFA level decreased significantly in rats given FSH. At the same time, FSH could inhibit the increase in body weight and Lee’s index. HRO could regulate the lipid metabolism and decrease serum TG level significantly in female aged rats with obesity. Conclusion: Both FSH and HRO can improve lipid metabolism in female aged rats with obesity.

Objective: To study the antihyperglycemic effect of flavonoids from seed (FSH) and fruit(FFH) of Hippophae rhamnoides L.on diabetic rats induced by streptozotocin (STZ). Methods: The STZ-induced diabetic rats were randomly divided into four groups and were given intragastrically (ig) water, metformin, FSH and FFH respectively once a day. After four weeks, the levels of serum glucose, fructosamine, lipid, protein, GSH and lactic acid (LD) were assayed. Results: FSH could reduce the levels of serum glucose, fructosamine and triglyceride significantly, increase the contents of serum total protein and albumin obviously, enhance the ability of antioxidation in STZ-induced diabetic rats. FSH also could decrease food and water intake of diabetic rats evidently. But FSH had little effect on LD, LDH, glycogen and body weight in diabetic rats. FFH was not as good as FSH. Conclusion: FSH is antihyperglycemic , and can improve the metabolic derangements of STZ- induced diabetic rats.
