Effect of Cement Dust Pollution on the Yield and Quality of Ficuscarica L. Fruits

The present study was carried out on Ficuscarica L. cultivated in the northwestern desert of Egypt. Plant materials （leaves and fruits） were collected from three polluted locations at a distance of 500-700, 1,000-1,250 and 3,000-3,500 m respectively away from the cement factory at EI-Hammam city, and a location of relatively clean air considered a control at 5,000-6,000 m away from this factory. The deposit cement dust washed from the surface leaf area of plant study was found to be 4.96, 4.21, 0.51 and 0.29 lag/cm2 at the four locations, respectively. Cement in more polluted locations increased mortality of young branches leading to a reduction in the height and yield of fig trees. The deposition of cement pollutants tothe loamy sandy soil of the present study alteredsoil chemical characteristics. The results showed that, biomass of fruits/tree, number of branches/tree and number of fruits/branch in polluted locations were significantly lower than those of the control one. Cement dust decreased leaf total chlorophyll content leading to a reduction in the economic yield （up to 50%）. Metabolic constituents （carbohydrates, proteins, amino acid and proline） and essential elements （Fe, Mg, Na, Ca, and K） were studied in two types of fruits on fig trees （mature and premature）. Thallium as a toxic metal was predicted in edible mature fruits, and the results showed that the concentration of thallium parts per billion （ppb） in polluted locations was significantly higher than those of the control one. The results revealed that fruits of fig plants at polluted sites showed quantitative and qualitative deteriorations.

PBO对不同品种无花果结果枝生长及结实的影响

采用3个不同浓度的PBO溶液对无花果叶面喷施,研究PBO对无花果结果枝生长和结实的影响。结果表明:PBO能有效抑制无花果结果枝的营养生长、侧枝发枝数量,且不同品种的抑制效果不同;喷施PBO能抑制‘ALMA’、‘杜鲁’和‘青皮’3个品种的节间伸长,当浓度为100和150 mg/L时,对‘青皮’节间的抑制效果最明显,‘B110’和‘波姬红’喷施PBO后,未见节间长度明显变化;喷施PBO后有降低无花果坐果率的趋势。

无花果叶提取物改善慢性宫内缺氧子代大鼠骨骼肌脂质代谢

目的探讨无花果叶提取物(FCLE)对慢性宫内缺氧成年子鼠骨骼肌脂质代谢的影响,及其潜在分子机制。方法随机将24只SD孕鼠分为常氧组、缺氧组及给药组,分别进行慢性宫内缺氧干预及子鼠出生后8周FCLE灌胃治疗。比色法检测血液学指标、骨骼肌脂肪含量、氧化状态以及RT-PCR法检测骨骼肌脂质代谢相关蛋白表达。结果与常氧组相比,缺氧组子鼠血脂水平升高,出现胰岛素抵抗且骨骼肌脂质含量明显增多[分别为(42.3±5.5)μmol/g、(59.9±6.4)μmol/g,P<0.05];脂联素、脂联素受体1(Adipo R1)及过氧化物酶体增殖激活受体γ(PPARγ)表达降低,乙酰辅酶A羧化酶2(ACC2)表达明显上调(P<0.05);FCLE干预后,血脂异常、胰岛素敏感性及骨骼肌脂质易位沉积均得到改善,脂联素、Adipo R1(给药组和缺氧组分别为0.61±0.10和0.22±0.07,P<0.05)及PPARγ表达上调,而ACC2表达降低(给药组和缺氧组分别为0.49±0.09和0.95±0.14,P<0.05)。结论 FCLE改善慢性宫内缺氧子鼠高脂血症、胰岛素抵抗及骨骼肌脂质沉淀;脂联素-Adipo R1-PPARγ-ACC信号通路可能是潜在的分子机制。

HPLC法测定阿图什无花果叶汁中3种香豆素的含量

目的高效液相色谱法(HPLC法)测定阿图什无花果叶汁中伞形花内酯、佛手柑内酯和补骨脂素3种香豆素的含量。方法色谱柱Sunfire C_(18)ODS(250 mm×4.6 mm,5μm),流速1 mL、min,检测波长为220 nm,柱温30℃,流动相为乙腈-水,流动相配比为0~10 min,乙腈25%;10~12min,乙腈由25%梯度增至50%;12~20 min,乙腈50%;20~22 min,乙腈由50%梯度增至100%。结果伞形花内酯、佛手柑内酯和补骨脂素分别在0.001~0.019 mg、mL(R^2=0.999 9)、0.01~0.19 mg、mL(R^2=0.9997)和0.01~0.19 mg、mL(R^2=0.9999)范围内与峰面积呈良好线性关系,平均回收率分别为98.09%(RSD=0.85%)、102.07%(RSD=1.07%)和101.00%(RSD=0.71%)。阿图什无花果叶汁中伞形花内酯、佛手柑内酯和补骨脂素3种香豆素的含量分别为1.09、9.89、24.58 mg/g。结论HPLC法简便、准确、稳定,可用于测定无花果叶汁中伞形花内酯、佛手柑内酯和补骨脂素的含量。
