By using two-stage separations indicates that, the content of total ketones compound by one stage separation is 12.14%, far lower than 54.95% by two-stage separations, and the content of pulegone and menthone increases from 3.37% and 3.46% by one-stage separation to 19.34% and 22.95% by two-stage separations respectively. But the content of the long chain unsaturated fatty acid and its ester ingredient reduces from 41.58% and 18.88% by one stage separation method to 29.06% and 9.86% by two-stage separations method respectively, also the phenol compound by two-stage separations method can been separated completely.

对荆芥挥发油采用两级分离的研究表明：酮类化合物的总含量由二级分离的54.95%远高于一级分离的12.14%，其中胡薄荷酮和薄荷酮的含量分别由一级分离的3.37%和3.46%增加到二级分离的19.34%和22.95%，而长链不饱和脂肪酸及其酯类成分含量分别从一级分离法的41.58%和18.88%降低到二级分离法的29.06%和9.86%，且二级分离法已完全除去酚类化合物。

The current analysis also supports a monophyletic Deinonychosauria containing the Dromaeosauridae and Troodontidae, but this relationship is weakly supported.

本研究也支持恐爪龙类是由伤齿龙类和奔龙类组成的单系类群，但这一结论的支持强度较弱。

The Anthraquinone element in Morinda officinalis How aids in the proliferation of BMSCs regardless of the polarity of the compound. Though the other compounds of Morinda officinalis How has a certain impact on the proliferation of BMSCs as well, it is of no statistical values. However, the result will be better for the Anthraquinone in Butyl alcohol as the polarity is wider.

巴戟天中的蒽醌苷类成分对促进BMSCs的增殖有效，而其他成分对促进BMSCs的增殖有一定的影响，但无统计学意义；且巴戟天蒽醌苷类成分无论极性大小，对促进BMSCs的增殖都有效，而正丁醇中极性较大的蒽醌苷类成分效果更好一些。

The experiment showed: 1PER, EST and AMY were polymorphic, meanwhile the isozymic chromatograph could identify the cultivars in this study; 2Two multifoliolate cultivars had specific isozyme loci PER-4, and the level of PER activity of the internal cultivars was higher than the external cultivars; 3 Genetic similarity and euclidean coefficient between the cultivars were 0.826-0.952, 0.500-1.118, between the multifoliolate cultivars were 0.904, 0.500; 4 Multifoliolate cultivares were classified for one type, and others for two other types.

结果表明：1测定的5种同工酶中过氧化物酶、酯酶、淀粉酶具有多态性，综合此3种酶酶谱可以鉴定供试的7个品种；22个多叶型品种具有一共同特征酶带PER-4，国内品种的过氧化物酶活性明显高于国外品种；3品种间的遗传一致度为0.826～0.952，欧氏遗传距离为0.500～1.118，多叶型品种间遗传一致度为0.904，欧氏遗传距离为0.500；4等级聚类分析结果为，以欧氏遗传距离0.400为分界，供试品种分为3类，2个多叶型品种为一类，其余的5种三叶型品种分为另两类。

So to study the evolution of CHS genes, the ideal data set should include the sequences of CHS genes from musci and other systematic groups of higher rank.

依据类黄酮物质存在与否，可推测CHS基因最早出现在藓类，因此，为研究CHS基因的进化，取材最好包括藓类和更高等的分类群。
