“…The difference between the lowest and the highest level of oil yield was over twofold (27.1 and 58.7% (w/w) dw in the genotype HL PSŠ 5 and Apguldes1, respectively) with the average amount of 45.6% (w/w) dw. In previous research where nine and seven apricot ( P. armeniaca L.) cultivars originated from Turkey and 17 germplasm accessions of Siberian apricot ( Prunus sibirica L.) originated from northern regions of China, similar values of maximum oil yield were reported, but the minimum values were higher – in the range between 40 and 45%.

“…The composition of fatty acids of potential feedstock have been stated to be an important factor affecting the quality of biodiesel . It is important to keep in mind that differences in fatty acid composition have been observed not only in seed and kernel oils recovered from various plant species, but also from different genotypes of the same species . Moreover, the fruit cultivation on the global scale continues to expand, including a vast array of new genotypes with specific characteristics, e.g., higher resistance to diseases, better fruit yield, taste, etc.…”

Kernels recovered from fruit pits of 14 apricot (Prunus armeniaca L.) genotypes are tested for future application as feedstock for biodiesel production. The difference between the lowest and the highest oil yield between studied samples is over twofold and reached between 27.1 and 58.7% (w/w) dw. The oleic and linoleic acids are the two dominant fatty acids in apricot kernel oils; however, their content is affected meaningfully by the variety and amounted to 38.5–67.2 and 26.4–54.8%, respectively. Two significant correlations (p < 0.000005) are found between oil yield in kernels of different apricot genotypes and two fatty acids, oleic and linoleic (r = 0.947 and r = −0.927, respectively). The biodiesel parameters of 14 apricot genotypes are calculated empirically according to previously developed equations based on the fatty acid methyl esters composition of the potential feedstock. The European biodiesel standards of kinematic viscosity, cetane number, density, and iodine value are met for 13 investigated samples. The exception was noted for genotype HL PSŠ 5. The recorded differences between minimum and maximum value of individual biodiesel parameters calculated empirically for various apricot genotypes differed as follows: 0.20 mm2 s−1 (kinematic viscosity), 4.9 (cetane number), 0.06 MJ kg−1 (higher heating value), 0.0028 g cm−3 (density), 15.6 I2/100 g (iodine value), 1.67 °C (CFPP), and 2.15 h (induction period). The logarithmic regression model in comparison to linear regression model, better expressed the relationship between physicochemical properties of biofuel and the ΣPUFA/(ΣSFA + ΣMUFA) ratio. To confirm the usefulness of the applied empirical equations for biodiesel parameters prediction of the apricot feedstock, five cold‐pressed apricot kernel oils of different origin and with a varied composition of fatty acids are tested experimentally and compared with the values calculated empirically. Practical Applications: Apricot kernels have limited use in food industry due to a high content of the amygdalin. Therefore, application of apricot kernels as potential feedstock for the biodiesel production seems to be reasonable, especially due rich oil yield (up to even 60%). In this paper the impact of the apricot genotype on the potential application in the biodiesel industry as well as the relationship between the oil yield and apricot biodiesel quality is described. Obtained biodiesel parameters of 14 apricot (Prunus armeniaca L.) genotype oils can help estimate the economic perspectives of utilization as a potential energy source. The present study may contribute to the more targeted use of the apricot (Prunus armeniaca L.) kernels and promotes the efficient management of the plant material and environmental sustainability. Kernels recovered from fruit pits of 14 apricot (Prunus armeniaca L.) genotypes are tested for future application as feedstock for biodiesel production. High oil yield 27–58.7% (w/w) dw and predomination of the oleic and linoleic acids 38.5–67.2 and 26.4–54.8%, respectively, is record...

“…Siberian apricot is widely distributed in China, so it has not been listed as an endangered or protected species and does not require any permission. Based on the collection and identification of P. sibirica germplasm resources of Wang et al (2012) [3], two germplasms (AS-80 and AS-84) with significant differences in oil content were used plant material in this study. AS-80 and AS-84 locating in Changping District of Beijing (geographical coordinates approximately 116° 23' E, 40° 22' N) were selected and marked in April 2018.…”

Background The oil content of Siberian apricot seed kernel (SASK) is generally as high as 50%, and biodiesel fuel properties of SASK oil were conformed to EN 14214 and GB/T 20828-2007 standards.Thus, Prunus sibirica is a novel non-crop feedstock for biodiesel production in China. We have been addressing this issue by studying the regulation of oil accumulation in SASK.Results As part of this research we have carried out a detailed lipidomic analysis in developing SASK.Here, oil contents and fatty acid (FA) compositions were studied in developing SASK from AS-80 and AS-84, at intervals of 1 week from 3 weeks after anthesis (WAA) to 9 weeks. The major differences between the two germplasms are higher contents of C18:1 and C18:2 in AS-80 than in AS-84 at a mature stage. The SASKs of 4, 6 and 8 WAA, respectively representing early, mid and late phases of oil accumulation, were selected as optimal samples for lipidomic analysis. The molecular species in individual lipid classes between AS-80 and AS-84 were similar, and exhibited quite distinct patterns with SASK development. Additionally, the lipidomic data coupled with qRT-PCR analysis suggested that three mechanisms allow the flux of FA through phosphatidylcholine that influenced the molecular composition of eventual TAG.Conclusions The first report on lipidomic analysis during seed development in wood oilseed plants.Our data contribute significantly to understand the underlying mechanisms of lipid accumulation in P. sibirica , and may also present strategies for engineering oil accumulation in oilseed plants. BackgroundSiberian apricot (Prunus sibirica) is a woody oil species that belongs to the Rosaceae family. As an endemic species in northern China, it is widely used for soil and water conservation owing to its superior adaptability to a wide range of environment [1]. Almost 192,500 tonnes of seeds are harvested in autumn every year [2]. The oil content of Siberian apricot seed kernel (SASK) is generally as high as 50%, of which about 95% is unsaturated fatty acid (FA), including 56.23-76.69% oleic acid and 16.44-34.69% linoleic acid [3]. Because the cost of feedstock account for the cost of biodiesel approximately over 75% [4], non-crop feedstock to produce biodiesel has drawn governmental and popular attention. Previous evaluation of SASK oil has shown that its biodiesel fuel properties, such as cetane number, iodine number and oxidation stability, were conformed to EN 14214 and GB/T 20828-2007 standards [3, 5]. Thus, SASK oil is a potential non-crop feedstock for biodiesel production.In plants, sucrose can be transported from photosynthetic tissues to heterotrophic sinks through the phloem. Once delivered into sinks, sucrose can be cleaved into two hexoses by either invertase or sucrose synthase [6]. In oil seeds, the generated hexoses are metabolized through the oxidative pentose phosphate pathway and the glycolytic pathway, providing acetyl-CoA as precursor for de novo FA synthesis [7]. After FA formation in plastid, a mixture of palmitic acid (C16:0), palm...
