| 2. | And the structure of flavonoids in h . crispate in different seasons is also different
不同结构种类的黄酮在植物体内的时间积累不同。 |
| 3. | In spring , the compounds in h . crispate were mainly flavanones , but in autumn , flavones were dominant
春季以二氢黄酮类为主，秋季则以黄酮类为主。 |
| 4. | In this paper , the constituents of h . crispate , including alkaloids , flavonoids , and triterpenes , were studied . huperzine a was first isolated from it
本项研究选择皱边石杉为材料，对其所含的生物碱类、黄酮类、三萜类等进行了系统研究。 |
| 5. | The result showed the content of hup . a in h . crispate was higher than that in h . serrata written in literature . the content of hup . a varied in different samples
皱边石杉中石杉碱甲在不同的季节内含量变化不大：石杉碱甲在皱边石杉中的含量以春季含量最高。 |
| 6. | The methods of determination of huperzine a , farrerol , and the total content of flavonoids in h . crispate were established . the relationships between the main constituents and the environment and seasons were studied
建立了皱边石杉中石杉碱甲、杜鹃素、总黄酮含量测定方法，并研究它们与环境及季节的关系。 |
| 7. | The researches on the determination method of main constituents and relationships between constituents and environment and seasons have also not been reported . h . crispate ching is a unique species of huperziaceae family in china
同时关于石杉属植物主要化学成分的含量测定方法、主要化学成分与生长环境及季节的关系等方面的研究都还处于空白状态。 |
| 8. | 3 relationship between main constituents and growth environment of h . crispate : the content of quick - acting potassium of the soil at the growing site was the positive correlating factor that correlates with the hup . a in the plant
0统计软件进行数据处理，结果显示： 1 ）皱边石杉中石杉碱甲含量与年平均温度呈负相关、与土壤中速效k的含量呈正相关。 |
| 9. | 3 ) the total content of flavonoids in h . crispate from different districts in different seasons were analyzed by spectrophotometryic method . the references were rutine and farrerol . the total content of flavonoids showed different numerical values in samples from different districts in different seasons
3 ）建立了采用分光光度法，分别以芦丁、杜鹃素为对照品，对不同产地、不同采集季节的皱边石杉中的总黄酮含量进行测定。 |
