The fatty acid profiles and tocopherol and phytosterol contents of crude oils of cress (Lepidium sativum L.) and field pennycress (Thlaspi arvense L.) are reported, along with yields from the corresponding seeds. The physical properties of these oils were also determined, which included oxidative stability, kinematic viscosity, viscosity index, low temperature fluidity, specific gravity, acid value, lubricity, and iodine value. The oil content of dried cress and field pennycress seeds was 22.7 and 29.0 wt%, respectively. The primary fatty acids found in cress oil were oleic (30.6 wt%) and linolenic acids (29.3 wt%), whereas field pennycress oil was principally composed of erucic (32.8 wt%) and linoleic (22.4 wt%) acids. Cress oil contained high concentrations of γ- (1422 ppm) and δ- (356 ppm) tocopherols, whereas α-tocopherol (714 ppm) was the primary tocopherol discovered in field pennycress oil. The overall tocopherol concentrations of cress and field pennycress oils were 1799 and 851 ppm, respectively. The primary phytosterols elucidated in cress and field pennycress oils were sitosterol and campesterol, with avenasterol also present in significant quantity in cress oil. The total phytosterol concentration in cress oil (14.41 mg/g) was greater than that in field pennycress (8.55 mg/g) oil. Field pennycress oil exhibited excellent low temperature fluidity, whereas cress oil was more stable to oxidation and over a range of temperatures displayed lower kinematic viscosities as well as a higher viscosity index. The acid and iodine values of field pennycress oil were lower than those for cress oil, but both oils had excellent lubrication properties.  相似文献

The seed oils ofParkia biglobosa andParkia bicolor (Mimosaceae) have been analysed for their possible edible utility and to provide some physical data on both oils. The fatty acid composition of the oils was identified. Six major fatty acids were identified in the oil ofP. bicolor while five were identified in that ofP. biglobosa by Gas Chromatography (GC) and Gas Chromatography — Mass Spectroscopy (GC — MS). The two oils contained five similar fatty acids in almost the same ratios. Arachidic acid was the most abundant fatty acids (greater than forty per cent) in both oils. Other fatty acids in the oils were behenic, stearic, palmitic and linoleic acids. The sixth fatty acid inP. bicolor was an odd number of carbon atom and un unsaturated fatty acid (C20H37COOH) named bicolargic acid. The oils were also found to be non toxic.  相似文献

Essential oils from 22 aromatic plant species were tested for mortality of the mosquito larvae Culex quinquefasciatus. Lethal concentrations were determined for individual essential oils. Essential oils obtained from Thymus vulgaris, Satureja hortensis and Thymus satureioides plants showed the highest effect, with LC50 found lower than 50 μg/ml (33, 36 and 44 μg/ml, respectively). Analyses showed that majority substances for T. vulgaris were thymol and p-cymene (60.3 and 10.1%, respectively); carvacrol and γ-terpinene for S. hortensis (48.1 and 36.7%, respectively), and borneol and thymol for T. satureioides (30.3 and 32.5%, respectively).The selected essential oils also showed very good effectiveness with respect to mortality and percentage of adult emergence upon short-term exposure in water contaminated with lethal doses of individual oils. While there was 77% adult emergence from the larvae in the control, in T. vulgaris, T. satureoides and S. hortensis there was only 12.3, 15.3 and 16.0% adult emergence, respectively. High antioviposition effectiveness was found in all selected oils. Almost 100% deterrence of female oviposition was determined for all oils in concentrations of 0.02%. Significant differences were seen with tested concentrations of 0.01 and 0.005%, where the oil of T. vulgaris proved most effective (repellency about 99.8 and 62.3%, respectively).  相似文献

Plants constitute an alternative source of proteins in the human diet, with advantages over animal proteins because of their low content of saturated fats and absence of cholesterol. Within the framework of a wider research project on the role of Amaranthus cruentus (Ac) in lipid metabolism, in this work the chemical composition and biological value of the Ac flour and its protein concentrate were compared. Proximate chemical composition, amino acid and fatty acid profiles, some antinutrient factors, and biological values were determined for Ac seed flour and its protein concentrate obtained by extraction at pH 11 and precipitation at pH 4.5. The flour protein content was 16.6 g% while that of the concentrate was 52.56 g%. The content of the soluble dietary fiber with a hypolipemic function was notably higher in the protein concentrate (12.90 g%) than in the seed flour (4.29 g%). The protein concentrate also exhibited a higher content of insoluble dietary fiber. The Ac flour and the concentrate contain 75.44 and 56.95% unsaturated fatty acids, respectively. Squalene, which affects the biosynthesis of cholesterol, was detected both in the flour and the concentrate oils, with a higher content in the concentrate (9.53%) as compared to the flour (6.23%). Comparison of the amino acid composition with the FAO pattern protein indicated that the concentrate does not have limiting amino acids, while the flour has leucine, threonine, and valine. The content of lysine was high in both the flour and the concentrate, making these products particularly useful as a complement for cereal flour, which is deficient in this amino acid. The biological quality analysis demonstrated an improvement in the quality of the concentrate. The presence of saponins, phytic acid, and trypsin inhibitors in the concentrate, which favor the metabolism of lipids, suggests that consumption of the concentrate might reduce the risk of heart disease.  相似文献

The essential oils obtained by hydrodistillation from the aerial parts of Tunisian native Hypericum perfoliatum L. (sect. Drosocarpium Spach.) and Hypericum tomentosum (sect. Adenosepalum Spach.) were analyzed by GC and GC–MS. Thirty-two compounds were identified in the essential oils of H. perfoliatum with α-pinene (13.1%), allo-aromadendrene (11.4%), germacrene-D (10.6%), n-octane (7.3%), α-selinene (6.5%) and β-selinene (5.5%) as main constituents. Sixty-seven components were identified in the oil of H. tomentosum with menthone (17.0%), n-octane (9.9%), β-caryophyllene (5.3%), α-pinene (5.2%), lauric acid (4.1%) and β-pinene (3.7%) as the most abundant components. Both oils were characterized by the presence of many components which could have numerous applications in food, pharmaceutical and perfume industries.  相似文献

In a two year field study, the effect of varying intensities of sub-lethal heating on the efficiency of Brassica amendments in controlling viable populations of Macrophomina phaseolina and Fusarium oxysporum f sp. cumini was determined in an arid region of India. After 30 d of dry summer exposure of pathogen infested soil, incorporation of mustard residues and oil cake (0.18% and 0.04% w/w) and then applying one irrigation caused significant reduction by 75.3–81.3% in viable counts of M. phaseolina that causes dry root rot of legumes and by 93.9% in counts of F.o. f. sp. cumini causing wilt of cumin (Cuminum cyminum L.) at 0–15 and 16–30 cm depths. Increasing duration of summer exposure to 60 d improved the reductions in viable propagules of M. phaseolina by 83.6–90.4% and in F.o. f. sp. cumini by 78.2–94.8% at same soil depths. At certain heat levels, reduction in viable population of Fusarium due to amendments and irrigation was greater than that recorded in Macrophomina. Significantly low levels of reduction in pathogenic propagules of Macrophomina (63.9–71.4%) and Fusarium (48.0–57.2%) under shade compared to unshaded conditions indicated that mild heating did not cause discernible weakening effect. In second season also, 89.2–91.5% and 78.5–95.8% reduction in counts of Macrophomina and Fusarium, respectively was achieved by the application of amendments after 60 d of summer exposure at 0–30 cm soil depth. These results suggested a new approach to improve the control of soil-borne plant pathogens in hot arid regions by combining prolonged sub-lethal heating, effective naturally available on-farm wastes as soil amendments and one summer irrigation.  相似文献

Comparison of the seed oil of Moringa pterygosperma (moringa) and Sclerocarya birrea (marula) showed a marked difference in fatty acid composition and oxidative stability. Moringa, with 1000 ppm tocopherols, had an oil stability index (OSI) of 133 h at 110 °C while marula with 1000 ppm tocopherols yielded 37 h at 110 °C. This correlated well with the fatty acid composition of these two oils. Moringa had less than 1% polyunsaturates and marula had 6.7% of these oxidatively unstable materials. In addition, fatty acid compositions of seven species of moringa are presented. All of these species had levels of behenic acid ranging from 1 to 7% with oleic acid levels from 68 to 79%. The highest amount of polyunsatures was found in the moringa species was in Moringa drouhardii with 3.6%.  相似文献

Using a PCR-based strategy, four new 75K γ-secalin genes were isolated from Secale cereale, Secale vavilovii, Secale sylvestre, and Secale strictum in genus Secale (rye). Based on amino acid sequences, the primary structure of the 75K γ-secalin subunits was demonstrated, which was composed of four main structural regions: (a) a conservative 19 amino acids signal peptide, (b) a steady short N-terminal region of 12 amino acids containing a cysteine residue, (c) a repetitive domain, which began with the conservative tetrapeptides PQ3 and was rich in glutamine and proline. PFPQ1−2(PQQ)1−2 was the core repeat motif in the repetitive region. Besides amino acid substitutions, this region showed variations in length due to the insertion and deletion events. In the repetitive region of EF432549 (Secale strictum), there were two octapeptides (PFPQQPQQ and PVPQQSQQ) insertions. On the contrary, deletion events of two residues (QT) took place in EF432546 (Secale sylvestre). Accounting for the amino acid replacement, an extra cysteine residue appeared in the repetitive region of EF432546, which did not exist in other genes, and (d) a conserved 143 amino acids C-terminal domain including eight cysteine residues. The implications of the results for quality improvement are discussed.  相似文献

为了解新麦草的种子产量及繁殖性状间的关系,对27份新麦草种质资源的单株种子产量与7个产量性状的关联性进行了分析。结果表明,新麦草的单株生殖枝数、穗轴节数、单穗小花数和千粒重与单株种子产量关联最密切,其相关性表现为单株生殖枝数＞千粒重＞穗轴节数＞单穗小花数。经通径分析,单株生殖枝数（X1）对单株种子产量（Y）直接效应最大,其余依次是单穗小花数（X4）、单穗小穗数（X3）、千粒重（X7）、穗轴节数（X2）和单穗结实种子数（X5）,其中单穗结实种子数和结实率对种子产量均表现为负效应,且未达到显著水平。经逐步回归分析得到回归方程Y= -9.880 2+0.27X1+0.012X4+2.011 1X7（R=0.805 8,P<0.001）,说明提高单株生殖枝数、千粒重、单穗小花数对新麦草增产的贡献最大,增加结实率也可间接提高新麦草的单株种子产量。  相似文献

为了给小麦育种提供新的种质资源,对4份圆锥小麦-乌拉尔图小麦双二倍体(AABBA^uA^u)的农艺性状、染色体组成及高分子量谷蛋白亚基组成进行了鉴定。农艺性状调查结果表明,4份双二倍体的株高介于108.45~129.43 cm,分蘖数介于7.3~17.5个,穗长介于10.23~12.17 cm,小穗数介于16.26~22.06,自交结实率介于37.77%~70.46%;4份双二倍体对目前的流行条锈菌混合生理小种(条中31、条中32、条中33、条中34和水源11-4)均表现为高抗。利用寡核苷酸序列探针Oligo-pSc119.2-1、Oligo-pTa535-1、Oligo-pTa71-2、pTa-713和简单重复序列探针(AAC)5进行FISH分析,可区分出圆锥小麦-乌拉尔图小麦双二倍体的42条染色体。花粉母细胞染色体配对观察表明,在这些双二倍体的减数分裂中期I,染色体大多配对成二价体,仅有少量的单价体、三价体和四价体。SDS-PAGE分析表明,来自于乌拉尔图小麦TA#831的1Ay亚基在双二倍体Syn-TAU-2中得到了表达,但其迁移率发生了变化;来自于PI428270和PI428274的1Ax和1Ay亚基分别在双二倍体Syn-TAU-3和Syn-TAU-4中得到了表达。这些双二倍体可作为新的资源材料用于普通小麦的遗传改良。  相似文献

The relative abundance of isoprenoids and other volatile components in the aerial parts of Artemisia annua Linn. (Asteraceae) after different nutritional treatments was analyzed by GC and GC/MS. Hydro-distillation of untreated (control) plants yielded 0.28 ± 0.04% essential oil on fresh weight basis. Monoterpenes were predominant in the essential oil of which cis-limonene-1,2-epoxide (22.1%), artemisia ketone (11.5%), iso-pinocamphone (11.4%), thujyl alcohol (9.9%) and camphor (8.4%) were the major components. The essential oil distilled from A. annua treated with Azospirillum (2 ml/plant) amounted to 0.30 ± 0.03% of fresh weight and consisted mainly of neral (31.1%), β-caryophyllene (25.1%), artemisia ketone (10.0%), thujyl alcohol (9.4%), trans-bergamotene (8.5%) and spathulenol (4.8%). The essential oil from plants treated with basal N, P, K and S application (in the form of urea P2O5, K2O and gypsum at a rate of 120, 50, 100 and 50 kg/ha, respectively) amounted to 0.32 ± 0.03% of fresh weight and consisted mainly of thujyl alcohol (33.3%), β-caryophyllene (15.5%), cis-undec-5-ene (14.4%), artemisia ketone (6.0%), trans-nerolidol (5.8%) and undec-4-ene (4.6%). The hydrodistillation of A. annua treated with Glomus (Mycorrhizal soil 50 g/plant) yielded 0.50 ± 0.02% essential oil on fresh weight basis. The sesquiterpenes were predominant in this essential oil and consisted of β-caryophyllene (51.2%), trans-bergamotene (15.4%), α-gurjunene (14.3%), germacrene D (5.1%) and ledol (4.5%) as major components. The only monoterpenes in the essential oil were neral, nerol and pulegone (each less than 1%). These findings suggest that A. annua treated with Glomus lacks glandular trichomes—the primary sites of synthesis of monoterpenes.  相似文献

A laboratory experiment was conducted with the poultry red mite Dermanysuss gallinae (De Geer) to assess the toxicity of a range of essential oils obtained from wild-growing plants in Tunisia to this pest. Details of the percentage essential oil yield from these plants were also recorded. For comparison, commercially sourced essential oil from Thymus vulgaris (L.) was also tested against D. gallinae after work elsewhere found this product to be acaricidal. Recently fed adult female D. gallinae were exposed to the essential oils at 0.1 mg oil/cm2 in Petri-dishes at 22 °C over a period of 24 h.Results showed that the yield of essential oil varied considerably depending upon the source plant. Whilst maximum yields of 0.5% were achieved, three of the seven wild plants selected provided yields of less than 0.1%. Similar variability was recorded with respect to the toxicity of the essential oils to D. gallinae. Three of the essential oils tested did not cause significant D. gallinae mortality (in comparison to the control). However, all other selected oils provided mortality levels statistically similar to the 90% mortality achieved with commercial T. vulgaris essential oil, with the oil from Pelargonium graveolens (L’Hér.) killing 100% of D. gallinae exposed to it. Essential oil from P. graveolens in particular may be suitable for further development as a D. gallinae acaricide alongside or in place of commercial thyme essential oil.  相似文献

醇溶蛋白盒结合因子(prolamin-box binding factor,PBF)通过调控籽粒蛋白的表达效率进而影响面粉的加工品质。为给深入研究小麦籽粒PBF对籽粒蛋白质表达调控的分子基础提供参考依据,进而为小麦面粉加工品质的改良提供候选基因资源,利用特异引物组合pbfF1/pbf R1分别从两份节节麦(AS90、AS2386)中克隆出pbf基因后进行序列分析,并进一步构建pbf基因的原核表达体系。结果表明,从两份节节麦中克隆得到了2个不同类型的pbf基因(GenBank登录号分别为KJ544771和KJ544772),其中来源于AS2386的KJ544772与来源于普通六倍体小麦的1个pbf基因序列完全相同。推导的氨基酸序列分析表明,KJ544771和KJ544772所编码的蛋白质均为弱碱性的亲水蛋白,具有典型的DOF蛋白结构域。与其他远缘物种来源的PBF比对结果表明,该类蛋白在NLS核心、DOF结构域及Ser铰链区相对保守,而在C-端调控区变异较大,说明PBF蛋白具有种属特异性。同时,系统演化树显示,来源于节节麦AS2386的pbf基因与迄今已知的全部普通小麦的pbf基因具有高度的相似性,因此推测该种类型的节节麦很可能参与了最初的普通六倍体小麦的形成。此外,本研究成功构建了pbf基因的原核表达体系,可为后续功能验证的开展奠定基础。  相似文献
