查询词典 heracleum

The results show that the pollen forms of Ferula and Heracleum are prolate and perprolate, respectively, and there are 3 colporates with reticulate sculpture on the pollen exines of the both genuses.

阿魏属和独活属植物的极轴平均长度分别为29.67μ m和34.07μ m，秩和检验表明二者差异显著；赤道轴平均长度17.07μ m和15.65μ m，差异不显著；极轴长/赤道宽的平均值分别为1.76和2.19，差异显著。

ConclusionThe extraction rate of volatile oils from Heracleum hemsleyanum Diels by supercritical CO2extraction process is higher than that of water vapor distillation,and the optimized extraction conditions are:extraction pressure 25MPa,extraction temperature 45℃ and flow rate of CO2 20L/h, and the yield of volatile oils is 0.65%.

超临界CO2萃取牛尾独活挥发油的萃取率较水蒸气蒸馏法高，最佳萃取条件为萃取压力25MPa，萃取温度45℃，CO2流量20L/h，挥发油收率为0.65%。

ConclusionMicrowave extraction has the highest yield in the shortest time. But volatile oil in Heracleum hemsleyanum Diels extracted by supercritical CO2 extraction or steam distillation has better quality. Thus the supercritical CO2 extraction is the best way.

结论微波萃取挥发油得率最高，时间最短；超临界CO2和水蒸馏法萃取挥发油的质量最好，因此使用超临界CO2是萃取牛尾独活挥发油的最佳途径。

Internal transcribed sequences of ribosomal DNA of 36 species wereanalyzed to reconstruct the phologeny of Heracleum and its related genera using themaximum parsimony, neighboring-joint and maximum likelihood methods inPAUP4.0b10, respectively.

选取独活属7种植物测取核rDNA中的ITS基因序列，结合GenBank已有的本属5种和邻近属24种植物的ITS序列，用PAUP4.0b10软件中的最大简约法、邻接法和最大似然法分别进行分析，从而对独活属及其近属进行了系统发育重建。
