采用0.2μl/L、0.5μL/L和1.0μl/L1-甲基环丙烯（1-MCP），0.05g/L、0.10g/L、0.15g/L乙烯利处理绿豆种子，测定种子发芽率、鲜重、下胚轴长度、乙烯释释放量、呼吸强度、总酚含量以及抗氧化活性等指标。结果表明，两种处理均提高了幼苗的鲜重、总酚含量，并提高了抗氧化能力。与乙烯利处理相反，1-MCP降低了种子的发芽率、乙烯释放速率和呼吸速率，促进了下胚轴伸长。

以大青皮石榴籽为原料，利用超声波技术辅助提取石榴籽油，研究了料液比、超声波功率、提取温度以及提取时间等因素对出油率的影响。试验结果表明，最佳工艺条件为料液比1:7（w/v），超声波功率70W，提取温度40℃，提取时间50min，出油率达19.81%。同时还研究了石榴籽油的理化特性。超声波辅助提取与常规法浸提和微波提取相比，具有出油率高、提取时间短、所需温度低等优点，便于石榴籽油的工业化规模生产。

Pomegranate leaves are an important source of potentially healthy bioactive compounds. Changes in total phenolics, flavonoids, alkaloids and antioxidant activities in pomegranate leaves were recorded from April 18th to September 16th, 2007. Total levels of phenolics and flavonoids decreased significantly in the early stages of leaf growth, and then increased gradually until the end of September. However, concentrations of total alkaloids increased during leaf growth and development. Antioxidant activities in pomegranate leaves were significantly correlated with the level of total phenolics and flavonoids. All bioactive compounds measured from pomegranate leaves increased during leaf growth and development. These trends suggest that the optimum picking time for tea is before May and bioactive compounds should be extracted from pomegranate leaves after August.
