利用气相色谱/质谱联用分析林麝麝香中麝香酮和甾类成分

采用气相色谱/质谱(GC/MS)联用的方法,对林麝麝香中的甾体成分进行分析,确定了林麝麝香样品含有多种甾体成分的结构,并分析了不同来源的林麝麝香的麝香酮及甾体成分。通过检索NIST05质谱库,进一步确定了麝香中含有16种甾体成分。利用外标法、标准曲线法同时测定了麝香样品中3种甾类成分(胆固醇、苯胆烷醇酮及麝香酮)的含量,麝香酮的定量分析显示所有样品麝香中麝香酮含量均较高(30.1～45.2mg/g),但甾类成分含量波动较大。聚类分析显示,9个麝香样品聚为两支。利用GC/MS技术检测麝香成分的方法,可以提

未成熟与成熟大豆油的成分及低温结晶特性分析Analysis of oil component and low temperature crystallization characteristics of immature and mature soybean

为研究大豆原料对油脂品质的影响，选取同一批次的未成熟与成熟大豆为原料，采用索氏抽提法提取大豆油，分析未成熟与成熟大豆油在理化指标、甘油酯及脂肪酸组成、微量组分组成及含量、低温结晶特性等方面的差异。结果表明：未成熟大豆油的酸值、过氧化值、茴香胺值、全氧化值、共轭二烯值均显著高于成熟大豆油的；与成熟大豆油相比，未成熟大豆油中二饱和一不饱和脂肪酸甘三酯含量升高了22%，其甘三酯、甘一酯、1,2-甘二酯、1,3-甘二酯的饱和脂肪酸含量增加了12%左右，并且其甘二酯含量是成熟大豆油的1.4倍；未成熟大豆油中磷脂酸含量是成熟大豆油的3.2倍，总生育酚、总甾醇含量比成熟大豆油分别降低了8.2%、13.0%，叶绿素含量是成熟大豆油的206.3倍；未成熟大豆油比成熟大豆油更容易结晶，在0 ℃时出现浑浊的时间更早，在-20、-15 ℃ 时的固体脂肪含量更高，并且其微晶形成及固态转变的温度更高，这可能与其含有较多的饱和脂肪酸、高熔点甘三酯及甘二酯有关。因此，在实际生产中应尽量减少未成熟大豆原料的占比，以提高成品油的品质。 In order to study the effects of soybean raw materials on oil quality, Soxhlet extraction method was used to extract oil from immature and mature soybean in the same batch, and the differences in physicochemical indexes, glyceride and fatty acid composition, trace components composition and contents,and low temperature crystallization characteristics of immature and mature soybean oil were analyzed. The results showed that the acid value, peroxide value, anisidine value, total oxidation value and conjugated diene value of immature soybean oil were significantly higher than those of mature soybean oil. Compared with mature soybean oil, the contents of disaturated monounsaturated fatty acid triglyceride in immature soybean oil increased by 22%， the contents of saturated fatty acids of triglyceride, monoglyceride, 1,2-diacylglycerol, 1,3-diacylglycerol in immature soybean oil increased by about 12%, and the content of diacylglycerol was 1.4 times of that in mature soybean oil. The content of phospholipid acid in immature soybean oil was 3.2 times of that in mature soybean oil, the contents of total tocopherol and total sterol decreased by 8.2% and 13.0% respectively, and the chlorophyll content was 206.3 times of that in mature soybean oil.In addition, immature soybean oil crystallized more easily than mature soybean oil, the turbidity time was earlier at 0 ℃, the solid fat content was larger at -20 ℃ and -15 ℃, and the temperature of microcrystalline formation and solid phase transition was higher, which might be related to the higher contents of saturated fatty acids, high melting point triglyceride and diacylglycerol.In actual production, the proportion of immature soybean in raw materials should be minimized to improve the quality of the finished oil

Amplitude analysis of the decays D0 → π+π−π+π− and D0 → π+π−π0π0*

Using e+e− annihilation data corresponding to an integrated luminosity of 2.93 fb−1 taken at the center-of-mass energy √s = 3.773 GeV with the BESIII detector, a joint amplitude analysis is performed on the decays D0 → π+π−π+π− and D0 → π+π−π0π0 (non-η). The fit fractions of individual components are obtained, and large interferences among the dominant components of the decays D0 → a1(1260)π, D0 → π(1300)π, D0 → ρ(770)ρ(770), and D0 → 2(ππ)S are observed in both channels. With the obtained amplitude model, the CP-even fractions of D0 → π+π−π+π− and D0 → π+π−π0π0 (non-η) are determined to be (75.2 ± 1.1stat. ± 1.5syst.) % and (68.9 ± 1.5stat. ± 2.4syst.)%, respectively. The branching fractions of D0 → π+π−π+π− and D0 → π+π−π0π0 (non-η) are measured to be (0.688 ± 0.010stat. ± 0.010syst.)% and (0.951 ± 0.025stat. ± 0.021syst.)%, respectively. The amplitude analysis provides an important model for the binning strategy in measuring the strong phase parameters of D0 → 4π when used to determine the CKM angle γ(φ3) via the B− → DK− decay

Measurement of integrated luminosity of data collected at 3.773 GeV by BESIII from 2021 to 2024

We present a measurement of the integrated luminosity e+e- of collision data collected by the BESIII detector at the BEPCII collider at a center-of-mass energy of Ecm = 3.773 GeV. The integrated luminosities of the datasets taken from December 2021 to June 2022, from November 2022 to June 2023, and from October 2023 to February 2024 were determined to be 4.995±0.019 fb-1, 8.157±0.031 fb-1, and 4.191±0.016 fb-1, respectively, by analyzing large angle Bhabha scattering events. The uncertainties are dominated by systematic effects, and the statistical uncertainties are negligible. Our results provide essential input for future analyses and precision measurements

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
